who we are.

Our mission is to help people use cannabis in the most effective way possible. By guiding patients to track their own cannabis intake, we will help to refine and improve treatment. It is our aim to advance the scientific understanding of cannabis and its legitimization as a therapy.

Stephanie Karasick

Founder & Chief Strategy Officer

Stephanie was born and raised in the suburbs of Montreal, and left shortly after getting her degree in Graphic Design. She moved to Toronto, working as a copywriter at Leo Burnett, Saatchi & Saatchi, JWT, Taxi, and MacLaren McCann over a span of 15 years. Somewhere in that time, she began studying photography, left the corporate world to work as an editorial and family photographer, and a mom. The idea for Strainprint came to her after her first few months of using medical cannabis, when she was noticing how little information and scientific validation there was on various treatments.

Alexander Repetski

Chief Communications Officer

Alexander Repetski is an entrepreneur, media production artist and communications strategist. He is not a scientist, but did minor in science in film school. Years ago, he began researching cannabis as an analgesic to control his own arthritis pain.

This interest became increasingly important in 2012 when his daughter Gwenevere was diagnosed with intractable epilepsy. He came across cannabis while researching various areas of neuroscience in an effort to understand treatment options. After repeated failures of traditional therapies, he has successfully treated Gwenevere’s seizures with specialized cannabis cultivars, extractions and formulations. As a result of his research and media appearances he is regularly asked to speak about his experiences and findings to audiences both within the cannabis patient community and within the academic world.

He enjoys hugs from his children and new ideas.
