There is no question: if we have complex numerical analysis needs, Berkowitz and Associates is the only place we turn. Over many years, Dr. Jonathan Berkowitz has consistently proven himself to be deeply skilled, insightful, creative, timely and, of course, accurate.

Jonathan further distinguishes himself through his marked communication abilities. He quickly puts clients at ease with his great sense of humour, his interpersonal warmth, and his rare ability to make complex ideas simple – both in person and in writing. 

We offer Berkowitz and Associates our highest level of recommendation, and know we will continue to work together for years to come.

Jonathan Berkowitz is the most user-friendly statistician I ever met, able to make complex concepts accessible and easy to grasp. He is a superb teacher who helped many UBC Family Practice residents and faculty design and complete research projects and also become more numerate in the process. He is very effective both as a presenter in seminars and as an individual consultant.

I have worked with Berkowitz & Associates extensively over many years. This has included the design, implementation, collating, and interpretation of complex statistical results subsequently published in several medical journals. They demonstrated attention to detail and were able to condense findings into a manuscript friendly format while ensuring a medical audience could easily assess the quality of study findings. Berkowitz & Associates combine academic expertise with common sense application. Highly recommended.

My colleagues and I have worked with Dr. Jonathan Berkowitz as an expert witness for several years on multiple different legal cases. He is a pleasure to work with. His expert reports include clear analysis and explanations. He makes statistical concepts easy to understand.

I came to Jonathan convinced I was not a statistics person. I left each session more capable than I thought possible. He has a gift for meeting you where you are, whether that means going back to first principles, rebuilding your confidence, or just explaining the same thing five different ways until it clicks. That foundation carried me through my PhD and into a career as a health services researcher. I once told him he was ‘the wind beneath my statistical wings.’ That still holds.

As the lead investigator for a multidisciplinary Ophthalmology team, I rely on trusted partners to support complex statistical work. Berkowitz and Associates have consistently delivered rigorous, insightful analysis that strengthens both my research and my team's output. Their professionalism and collaboration make them an invaluable extension of our work.
