Team - Medical Directors, Executive Team and Directors

Dr. Mark Percival is our CEO, Chairman and co-medical director. Mark has extensive and unique experience in the healthcare field. For the last two decades, Mark has co-led the development of systematic approaches to systemic healthcare. As the original founder of Health Coach^®, Mark was advocating and enabling “health coaching” long before the need for this emerging area of healthcare caught the attention of national media. His international audiences have included thousands of health practitioners and members of the public throughout Canada, United States and Australia. However the past 10 years have been dedicated almost exclusively to the development of web-based assessment and education systems.

Dr. Percival is dual licensed as a doctor of Naturopathic Medicine and Chiropractic and continues to run an active practice 1 week a month, which he refers to as his “real world laboratory”. His patient successes continue to inspire him, and those around him, to co-create the systems that enable broader access to the resources he has found so valuable.

With Health Coach^® and its sister companies within The LifeStrive Group, Dr. Percival continues his role in co-developing and teaching systematic approaches to systemic healthcare.

He has been a consultant to the nutritional supplement industry for the past decade and has more than 18 published articles (indexed on Medline) on various aspects of natural medicine, nutrition, and metabolism. He is a recognized author, having contributed three chapters to the Textbook of Natural Medicine, 2nd edition, by Murray and Pizzorno (published by Churchill Livingstone, 1999), and is soon to release the first book in a new Health Scene Investigation series he is co-authoring with Dr. Percival with input from fellow Health Coaches.

Dr. Kelly is a naturopathic physician (N.D.) and has taught courses on Advanced Nutrition, Doctor/Patient Relationships, Counseling at the University of Bridgeport, College of Naturopathic Medicine, and Sports Nutrition at Southwest College of Naturopathic Medicine and Health Sciences.

Dr. Richard Perryman originally joined Health Coach^® in 1994. It was immediately evident that he had a level of enthusiasm and foresight that was extraordinary. Since that time he has been leading the development of Health Coach^® Corporate Wellness Initiatives. In 2005 this led to his co-founding of our LifeStrive^®-Health Coach^® programs and what many believe to be the practical and innovative corporate wellness solutions that are required to transform the growing healthcare crisis in America.

It is Dr. Perryman's belief, and indeed the belief of our teams at Health Coach^® and The LifeStrive Group, that a shift to a more collaborative, health promotion and education focused, self-responsible health care model is not only logical, but is now driven by market forces that make it inevitable. The early adopters of this model will be corporations as the single largest stakeholders in healthcare.
