Adrian is proud to call Canada home – he did most of his early training in Calgary – in family and sports med. While working with a multidisciplinary rehab team, he added further training in chronic pain management, but his interests went beyond medications and steroid injections.
In 2002, he learned about and started trying Prolotherapy, and both he and his patients were impressed with the results!
He learned so much from wonderful teachers, as well as his patients. Later he added Ultrasound guidance to more clearly and safely pinpoint the targets for injection.
Over the years he has found Prolotherapy to be one of the most valuable tools in pain and rehab, if done well.
Adrian enjoys cycling and skiing, travel and photography.
In addition to teaching and learning, it is an ongoing pleasure to be contributing to a standardized way of teaching effective Prolotherapy.
