Lisa has helped us move much further ahead in our TOC journey. She's very engaging and explains things in a clear way. It's a joy to work with her!

Lisa's a really great listener and she asks fantastic questions to lead you down a path of your own discovery. She's extremely approachable, extremely accessible. Her style is very personal warm, with confidence.

I was fortunate to find “Jonah” when I assumed the role of Head of Commercial. Faced with thorny issues, I felt lost and bewildered for the first time. Where should I even begin? In just a few coaching sessions, Lisa taught me how to apply the TOC thinking process to identify the underlying conflicts and clarify key assumptions. She made TOC accessible and practical. With her guidance, I successfully applied the techniques, leading to immediate positive changes at work. This experience has been truly transformative, and I wholeheartedly endorse Lisa for any organization in search of a TOC expert and master educator.

I am a Jonah’s Jonah and have undergone rigorous training in Thinking Processes, but I find your program worth every penny. I plan to use it immediately to teach my Oral & Maxillofacial Surgery and dental residents while making clinical and practice management decisions. Evidence-based medicine provides some validity to our assumptions, but it doesn't establish causality. By challenging assumptions, we can unearth several confounding factors in establishing cause and effect.

I took the Assumption Hacking Essentials course and found it extremely helpful! I loved the content and the frameworks, as well as all of the examples from various business and life situations. I've been testing the teams I work with on surfacing the assumptions that are going into our own daily conversations. It's been a really powerful tool especially when we discover disagreement about the assumption being made!

Testimonial for Lisa My name is Anil Jain from India , I am a TOC practitioner and learnt a lot from Lisa in last 7 years. Recently I had the privilege of having a long session with Lisa, a world- renowned TOC expert. The session with Lisa was wonderful and insightful. It provided me with many new perspectives on the real essence of the Theory of Constraints (TOC). One of the most valuable lessons I learned was the importance of identifying and invalidating wrong assumptions. Lisa taught me how to ask the right questions to guide people in the right direction, leading to effective and sustainable solutions. The best thing about this session is Lisa's ability to break down complex concepts and present them in an easily understandable manner. Her approach not only clarified my understanding of how to make potential clients buy into TOC services but also equipped me with practical tools to achieve the best results. I am truly grateful to Lisa for her mentorship and the profound impact she has had on my professional growth. Thank you, Lisa, for your exceptional guidance and support. Warm regards, Anil Jain

Hi - May name is Jeff Galas, I am a sales person, a consultant and a student (well over 30 years as a student). I have participated in many of Lisa's programs and love them. They are straight forward, approachable and easy to grasp. However, all of that is nonsense compared to a simple fact. Lisa has helped me implement the training in real time on real situations. The clarity of thought is refreshing while being a bit frustrating I wasn't there already. It never seems big - which is the power of the thought she provides.

I attended to the Mistery conference on 4/1/2024. The need to promote the use of logical thinking is critical in order to leave a better world behind our actions. And to check the assumptions that connect needs and actions has been the top surgeon management challenge. Thanks Lisa for providing and promoting this TOC thinking processes.

Even just Lisa's short and free 'Mystery Analysis Webinar' helped me understand a tool I look forward to using during implementation, as a systematic and pragmatic way of understanding why results differ from expectations. I've otherwise come across few writings on the experimenting or prototyping stage in the ToC world, and the Mystery Analysis tool has plugged a huge gap in my head. I also highly highly recommend Lisa's chapter 25 in the Theory of Constraints Handbook, and her talk on the Strategy and Tactics Trees. Thank you, Lisa!

I loved your assumption hacking essentials course! Thank you for creating it. 😁 I've been struggling with understanding and practising TOC thinking processes for a while. Your assumption hacking essentials course manages to provide a strong scaffolding and yet gently introduces one to the basics of modelling the TOC-TP way. I'm looking forward to putting what I've learned into practice, collaborating and teaching. Also, I can't wait for your future courses to be released.

I just finished Assumption Hacking course. I am a big fan and practitioner of Thinking Tools, but this is exactly what I was missing - the necessary foundation. Thank you!

Your testimony is excellent, moving and instructive...thank you!! I will share it with my partner who has experienced difficult times associated with deaths of relatives...
