Tarek

My time being coached by Tarek was truly fulfilling. From our very first meeting, we built a strong and trusting relationship that allowed us to have deep and meaningful conversations. He challenged me when necessary, encouraging me to think beyond my limits, while also providing steady support as I worked toward my own goals and outcomes. His balanced approach helped me gain clarity, confidence, and real progress. I’m very grateful for the experience and would highly recommend him as a coach.

I completed a brief coaching journey…

I completed a brief coaching journey with Tarek and found it incredibly helpful. Although we only had a few sessions, Tarek successfully shared practical concepts that I could apply immediately. This has given me greater self-awareness and, consequently, made my approach with my team and peers more effective.

Great experience

I had the pleasure of participating in a short coaching journey with Tarek, consisting of three sessions. From the very beginning, Tarek demonstrated exceptional professionalism, deep expertise, and a genuine ability to listen and guide. His approach helped me gain clarity on several key aspects of my role as a manager of a small team, and I came away from each session with valuable insights and actionable strategies.

Tarek created a safe and constructive space for reflection, and his questions were always thoughtful and impactful. Thanks to his support, I was able to focus on areas that needed attention and feel more confident in my leadership.

I recommend Tarek to anyone seeking a coach who combines deep expertise with a genuine passion for helping others grow. His thoughtful guidance and ability to create meaningful conversations make a real difference — working with him was not only insightful, but also truly energizing.

A very Pleasure

I had the pleasure of participating in a one-on-one leadership coaching program with Tarek. It was an extremely enriching experience, both professionally and personally.

Tarek proved to be highly professional, competent, and at the same time empathetic and human. Thanks to his support, I was able to reflect deeply on my working methods, my limitations, and how to address and overcome them concretely and effectively.

This program helped me grow, strengthen my awareness, and develop new perspectives on my leadership. I highly recommend this experience to anyone who wants to invest in themselves and improve their leadership and management skills.

I really enjoyed Vanessa’s presentation yesterday. Her storytelling was amazing, it drew me in and made it so easy to visualise myself in the situations she described.

Just completed an incredible leadership coaching

Most valuable part of the process was gaining the ability to reflect on my leadership style and adapt it to meet the unique needs of each individual on my team. One of the biggest breakthroughs for me was learning to differentiate agreement from alignment.

We also explored the 4C model of leadership, and two pillars that really resonated with me were Clarity and Consistency.

Tarek, I’ve very grateful for the insights, challenges, and growth. Learning to lead with more clarity, confidence, and purpose has been wonderful.

Professional & Analytical

I was fortunate to have had 3 months of professional coaching w. Dr. Tarek. Though it was a short period, it definitely was enough to spotlight some of the areas that I could develop in my day-to-day actions in a professional setting. Tarek is very good at asking the right questions to dig deeper and to get to the root cause of the matter. Would highly recommend for sure - and thanks Tarek!

A powerful Step in My leadership Growth

I had the opportunity to complete the 360 assessment with Synthosys, and it was truly a game-changer for my career. It allowed me to evaluate my leadership and management skills, providing valuable insights into my leadership style—particularly in areas like teaching and delegating tasks within my team. More importantly, it made me realize that while I often doubted myself and my abilities, my team and colleagues recognized the value of my contributions.

This assessment has significantly improved my management skills, helped me identify my weaknesses, and given me the tools to work on them. I am incredibly grateful to Synthosys for this insightful and valuable experience, and I highly recommend it!

Coaching bienveillant

J'ai eu la chance de bénéficier de l'accompagnement de Tarek dans le cadre d'un programme de coaching de mon entreprise.
Nos séances étaient des moments privilégiés qui me permettaient recul, mise en perspective mais aussi responsabilisation.
Je tiens à le remercier pour sa bienveillance.
Je pense que ces conseils m'accompagneront sur mes prochains challenges.

I was lucky to benefit from Tarek's support as part of a coaching program for my company.
Our sessions were special moments that allowed me to step back, put things into perspective and take responsibility.
I'd like to thank him for his kindness.
I think this advice will help me in my next challenges.

An awesome leadership experience

I worked with Tarek for 6 months after I'd worked as a design manager for a year. The 6 months were pivotal for me and very eye opening. Tarek was able to provide me with actionable steps I started utilising on day-to-day basis with my own team. The topic ranged from improving performance of my team, accountability and building more diverse teams. I cannot recommend Tarek and Synthosys enough, whether you are a seasoned leader in your field or just starting up, I'm sure you'll benefit from this type of coaching

He led me in a smart way, understanding my background, providing advices when needed and questioning when required. I would recommend his support and services without hesitation and I would work with him again without any doubt! Thanks a lot!

Therapy Promoted Emotional Well-Being

I have been seeing Vanessa Pozzali through our company's therapy program, and her empathy, professionalism, and insightful guidance have profoundly helped my mental health well-being.

During my time with her I gained valuable coping strategies and a renewed sense of clarity and confidence in myself. I highly recommend her to anyone in need of compassionate and effective therapy, sometimes you don't know that you need help until you seek it.

Really helpful mentoring experience!

Jomaa was very approachable, practical and knowledgable at all time during our sessions. He was also very empathetic and flexible to adapt to my changing needs. He helped me hone down a good toolbox to help in my decision making process as I was navigating career changes and a reshuffle of my personal priorities.

Multifaceted, Action-oriented & Supportive

I’ve had the opportunity to get coaching sessions with Dr. Tarek over the span of three months as part of a global ambassadorship program.

By prioritizing providing a safe space to his clients, Dr. Tarek helped me explore different aspects of my life related to the program and beyond. He challenged some of my thoughts and supported me throughout the process. He gave me tools that I can use to overcome my personal and career challenges.

The session was not just a conversation. We always had actions to take or questions to reflect on after each session. It was more about taking action than talking. He told me once that "coaching happens between the sessions" and I totally agree with him.

I highly recommend Dr. Tarek. His experience, wisdom, and knowledge are inspiring and make him a wonderful mentor and coach.

Great Sessions, Amazing Discoveries

Tarik is a true professional in the realm of psychology and development, what I found extremely unique was his robust analytical background, Tarik runs his sessions in a very relaxed and open manner , you feel naturally at ease to discuss any idea or matter that you'd like to delve into it and then he possess the skill to dig deeper and find a true cause, reasoning or merely ask an open ended question that shifts your world view on a problem you've been tackling for a while and once that shift happens you understand the true value of his expertise in pinpointing that "mental knot".

(Context)
I met Tarik through a prestigious diplomacy bootcamp that I was enrolled in where he was a mentor on the program, all throughout the various sessions he managed to propel my psyche and allowed me to uncover lots of discoveries along the way.

Highly recommend, il be meeting Tarik again on a seasonal basis.
