Super positive experience! Zack equipped me with tools/framework for better understanding and analysing underlining drivers of my intentions and actions. He helped me to get more clarity with what I want in life and how to achieve that. Zack is smart, humble and absolutely amazing person to talk to!

Zack truly cares about creating a meaningful conversation and is a great listener that tried to push myself to see my behaviours and thoughts from a different prospective. Finally possible paths are explored.

Thanks for Zack’s Personal Coaching Experience. Soho House Berlin is a vey cozy place to have conversations. Zack surprised me with his theory, and I’ve had better understanding of myself and my relationships.
— Liang, Vantaa (September 2020)
Im so glad I booked this experience with Zack during my time in Berlin. I found tremendous value in this session and left feeling empowered, encouraged and very clear on the next actionable steps I’ll be taking. Zack is super knowledgeable, offers amazing insights and the session is really well structured to cover what’s needed. The venue choice is great as it was lovely to see Soho House, too. I highly recommend this session and Zack - thanks again!
— Lena, London (September 2020)
This is a wonderful experience. When I booked this session I had no idea what I expected from it, but when I finished the session I had much clear idea about my life, both for the past and for the future.

Zack is a great trainer, he listened carefully, the conversation flowed and I have reflected a lot and learned a lot from the session. For anyone who experiences bottleneck in his/her life, career, relationship, I would highly recommend it! It might open a completely new chapter for your life!
— Xi, Berlin (August 2020)
Zack is a great Coach, he’s undoubtedly an experienced and knowledgeable person. I enjoyed the session a lot and he helped me to unlock quite a few elements in my professional life that need more attention.

Zack himself is a great person, and I enjoyed this more than I expected. I will follow up with him for sure and work on more details to take the understanding of my behaviour to the next level!
— Steffen, Berlin (August 2020)
Zack’s personal coaching session was enlightening, engaging, and highly valuable. He made me feel comfortable to express what I needed but equally posed myriad questions to help me think more critically about what I’m looking for in life. The exercise was very personalised but structured and only a few hours later, I find myself applying his teachings to personal situations. Thanks again, Zack, for a fantastic two hours of new connection and clarity.
— Jasmine, Edinburgh (July 2020)
I met Zack two days ago finally after thinking of meeting him since last November. The timing was perfect, but if you’re on the fence about booking a session with him then I say dive in. Don’t wait. I came to Zack talking a fierce game about specifics and what I thought I knew about my weaknesses / shortcomings, but he helped me zoom out and get my eye back on the ball of the bigger picture: being a good human. Whatever it is you’re going through in your life right now that has led you to consider a coaching session with Zack - just do it. He is an extremely intelligent, kind, and considerate coach who has clearly gained a lot of experience in his field. I highly recommend you take this life changing chance and book him for a session!
— Sam, Montreal (February 2020)
Zak is a really amazing guy and cares a lot about his clients. I left with a much better clarity in my life and a new friend. Would definitely recommend!

Zack is an awesome and knowledgeable coach. He provides enough structure to support and guide you through the session while making it personalized by opening up the focus to what you want to work on. Afterwards he gives you tools and resources that you can work with after the experience. Overall, cool guy and nice venue. Definitely recommend, his sessions are a great value and investment in yourself!
— Christina, New York (January 2020)
I think, this is something everyone must do ! Evaluate your life... Ask you questions about yourself... How many of us do this ? Thank you for opening my eyes, Zack. This meeting was very important for me! I recommend this session with Zack to everyone, who wants to know what is important in life and how to get there. Just dare!
— Tom, Berlin (December 2019)
Book this session if you need help or are uncertain figuring out: what do I want? what are my ambitions/goals? how do I prioritize them? and how do I get started? If you need any help with these questions, do not hesitate: Zack will help you make unexpected progress. At the end of the session, I got more clarity, tools and encouragement than I ever got out of a two-hour conversation. A remarkable experience. Genuine breakthrough. Very powerful. Zack is an amazing listener and a fabulous coach.
— Tom, Amsterdam (December 2019)
This was such a unique and thoughtful experience. I highly recommend for anyone who is in Berlin and wants to get to know themselves a little better. Zack is very knowledgeable and thorough in his work. Plus the location is Great.
— Raana, San Francisco (November 2019)
Really good time to reflect and dig deeper into yourself. Zack will help you and guide you throughout this process. Good outcome and definitely good experience to have wether you’re lost in life or you need to polish a few thoughts.
— Hadi, Abidjan (October 2019)
True breakthrough Zack told me I wasn’t his usual type of client but I felt he personalised the experience so that I could get the breakthrough I needed when I felt stuck in my life. I am grateful for this experience.
— Chiara, Cardiff (October 2019)
If you are looking for a unique experience while in Berlin, Zack can help with that. From the location of our meeting to its content, Zack provided great value and thoughtful personalization to help me unravel and better understand myself. I was able to gain clarity on my modus operandi and walked away with solid strategies on improving myself and my business model to ensure my success. I even had specific action steps to implement once back home. I had a wonderful time soaking in Berlin, but the best use of my time in the city was easily spent with Zack discussing my future and gaining some confidence on managing the present. If you are struggling with what you are currently doing, are feeling stuck in your daily interactions, or simply want to better understand your blind spots, I highly recommend you spend some quality time with Zack. Your future self will thank you!
— Fatma, Washington (September 2019)
It was a great experience to meet Zack. I decided to book a session with him after reading all his positive reviews, and I cannot do anything more than confirm them now. This experience was really eye-opening, Zack helped me to look at my life/career from a different point of view and give me some clear inputs to define where I want to go and how to practically get there. Moreover, his coaching doesn’t really end after the session, Zack takes his time to make some follow ups and stay available in case of questions. I highly recommend this experience. Plus: the rooftop view in Soho was amazing, definitely worth to see it once.
— Fabiana, Luxembourg (September 2019)
I warmly recommend booking a coaching session with Zack! He made me feel very comfortable from the start, and we covered a lot of ground during the session. The varied activities and resources we used allowed me to see things from a different perspective, have a few important realisations and leave with new strategies to help me better reach my goals. Zack truly cares about his work and delivers great value. The venue (Soho House) was also very special and added to the experience. This was the most interesting thing I did in Berlin!
— Marie, France (September 2019)
Meeting Zack was a great experience and was incredibly helpful in this moment of my life. I would definitely recommend a coaching experience with him: he focuses 100% on you and guides you in the discussion about the topics you care the most in a very intelligent and “delicate” way, asking the right questions and offering his deep knowledge, at the same time leaving you the space to come to your own conclusions. He’s able to provide small advices that might help you in the daily life, as well as a list of resources that will help you continue reflecting on your own. THANK YOU ZACK!
— Paolo, Milan (August 2019)
This coaching session was just what I needed as I was nearing the end of a long trip and was in need of some reflection & prompts looking forward. Zack provided some really amazing resources for me- and recommendations for things to do in Berlin!
— Abby, Seattle (july 2019)
I loved this experience! I left feeling so much better about myself and moving forward from trauma. Zack is a great guide!

A must book for humans who want a serious change in their lives. If you are visiting a city where Zack is currently working and you are open minded for learning something new about yourself and let someone reflect your past accomplishments and current thoughts, you should meet Zack. He truly helps you out! We had a really nice session at 10.30 am in the morning. The conversation was so interesting, he even stretched the time for me. Zack is a really calm and nice guy. But furthermore, he is listening careful to your words and gives you a mature and logical help with a lot of confidential knowledge he gained over the years. He is highly recommendet from my side, and I am sure that his succes journey just began. Zack is worth the money and you have the possibility to contact him after your appointment if there are any questions.
— Dennis, Edewecht (October 2021)
I had a great experience doing the coaching session with Zack. I would recommend this experience to others and would also do it again myself.
— Artiom, Tel Aviv (September 2021)
I had no expectations coming into this, but speaking with Zack gave me more clarity on next steps in life and insights on myself, would recommend!
— Tony, San Francisco (August 2021)
The personal coaching with Zack was very special for me! I had no expectation, but was very curious and open. Zack has a remarkable sense of someones feelings and needs and knows how to activate all the ressources to work on them within two hours! I felt listened, taken seriously and understood to my problems and goals. I left the coaching with a list of To-Dos, confidence and new perspective! Thank you for two very powerful hours!
— Sultana, Berlin (August 2021)
It’s easy to lay your cards on the table with Zack in front of you. He has great knowledge in what he is doing and he helped me with my next steps in life.
If you have any doubts about what you are doing with your life, go to Zack as he knows how te clear things up!
Very recommended if you think you require some professional expertise.
— Vincent, Friesland (October 2020)
Sometimes, a stranger can have a better understanding of where one stands; offer an accurate, honest feedback; and an educated reality-check - un-polluted by the shield of appearances we wear daily. You half-jokingly book a meeting with a stranger, because, hey, what can happen? Serendipity. It sometimes happens.
— Radu, New York (August 2020)
Zack is an incredible professional—in the two hours session not only he helped me find insights about my personal life, but he also provided broad conceptual background information that helped me to understand the process and rationale behind it, while keeping it fun and light-hearted. Don’t miss it out!
— Ruy, Barcelona (August 2020)
I am so grateful to have taken the time and meet Zack. He was super personal and you can tell that he is passionate and knows what he is doing. No matter what stage in life you are at, I recommend this experience to everyone! Thanks Zack!
— Pary, Dusseldorf (July 2020)
This experience was highly fulfilling. Zack is very knowledgeable and attentive coach. What was the most important - I felt support and encouragement.
— Ganna, Berlin (March 2020)
Highly recommend a session with Zack for those who would like to learn about yourself and where you would like to be in life.

Zack is an excellent coach and he takes care of client needs very well (time management, my need for breakfast, my luggage as I was catching a plane afterwards). Bravo!
— Helen, Hong Kong (February 2020)
All in all, it was a fantastic experience! Zack is an expert in his domain and can really help you to focus on how to overcome your current career challenges!
— Fabian, Basel (December 2019)
Zack training and coaching helped me figured out where I am at and where I want to head to in already one session. He gaves me great insights into how I could implement more efficiency in my life, get much more out of my business, and also protect myself emotionally. His coaching is caring and insightful, yet doesn’t shy away from the real questions one must ask to progress further. I feel after this one session that he can assist me into reaching my full potential, which is the aim of great coaching. As a bonus I was delighted to discover Soho House Berlin. This session was an incredible value for money and I highly recommend it.
— Laurent, Berlin (December 2019)
If anyone feels the description of this activity is something they could use, even just a little, I highly recommend booking a session. Zack will cater to you individually and guide you through like a genuine and caring friend, while still keeping the session structured. So whether you feel directionless in life or just feeling too much mentally, go with an open mind and not hold onto any expectations, and I promise you’ll learn something about yourself. I hope you leave feeling motivated, more understood, with more purpose, or simply feeling a bit lighter overall.
— Julia, Chicago (November 2019)
I met with Zack on Halloween and I been trying to find the words to express how excellent this personal experience was for me. If you’re seeking to enhance your personal growth by learning more about yourself, then book this experience.
— Shurron, Los Angeles (October 2019)
Highly recommended! I didn’t know what to expect before meeting Zack and was a little nervous but as soon as we met he made me feel very welcome and it was a very comfortable conversation. The meeting place was perfect, quiet enough to have an in-depth conversation but also relaxed. I left the experience with more clarity and motivation, feeling empowered! Absolutely worth the money!
— Rosanna, Frankfurt (October 2019)
Zack will probably be one the most influential people you will ever meet in your life. He is patient, extremely knowledgeable and most importantly, he cares about you and what you are trying to accomplish in your life. Out of all the consultations or seminars I have attended, my sit down with Zack was absolutely the best- no question! I would write a longer review and give an extra star, but I think it’s best you discovered it for yourself. Cannot recommend meeting him enough, DO IT!
— Atheer, Orlando (September 2019
I wasn’t sure what to expect coming into this unusual experience and I was very pleasantly surprised. Zack is extremely empathetic and was able to quickly come up with valuable advice tailored to my situation. Unlike other coaching sessions that provide cookie-cutter exercises and solutions, Zack used his framework and expertise to customize exercises and discussions to my particular situation and questionings, which I really appreciated. By the end of the session, I had a clear road map to take action on personal development and saw my situation with a fresh, different perspective, which is exactly what I was looking for initially. Highly recommended!
— Aurélien, Washington (September 2019)
This experience is a must if you have the chance! I honestly had no idea what to expect but I came out of this session with a new sense of purpose and direction. Zack really helped me breakdown my life until now and most importantly, gave me the tools and confidence to work out what it is I want next. Thank you Zack for listening to me, asking thought-provoking questions and giving me the confidence to push things forward!
— Blake, Southampton (September 2019)
Time well spent to reflect on your personal life. Zack has a profund background and is asking the right questions. I would recommend this experience to everyone coming to Berlin, for me it´s part of self care and mental health. Next to a bit of work it is really fun and Zack a wonderful person worth getting to know.
— Katharina, Cologne (August 2019)
Zack’s experience is a “1 on 1” guided tour through your own mind and thoughts. Great opportunity to reflect on your conversation and find focus in your life. Zack also gives you a book to read over so you get to take away some of his knowledge with you. The meeting is set in the very trendy SoHo House and this in itself is an experience. The 2 hours passed by so fast so all I can recommend is to try have an idea of what you want out of it. Zack is very generous and I can highly recommend to make this experience part of your Berlin say if you are looking for something unique.
— Dieter, Johannesburg (August 2019)
I had a wonderful session with Zack. He helped me breakdown/evaluate my present life, imagine what a perfect life would be and then figure out what steps I could take to achieve it. I think this short session will have some long lasting impact in my life, it was just what I was looking for. Thank you Zack.
— German, Phoenix (July 2019)
Zack’s session provided me with valid, meaningful feedback/steps for pursuing my goals. I walked away feeling that we had addressed all of the varied ground that I felt was relevant to me. Zack is a warm, friendly, interesting guy that will make you feel at ease discussing difficult topics. On a more specific note, Zack suggested a book (purchased later that morning) that was incredibly pertinent; from this, I gathered that he has a solid depth of knowledge in his field. He also followed up with a thoughtful email summary, that highlighted the steps we discussed and provided a few additional thoughts.
