Dr. Mark Percival is our Chief Executive Officer. Mark has extensive and unique experience in the healthcare field and is considered by many health professionals to be the industry leader in the development of systematic approaches to systemic healthcare. He is the original founder of Health Coach® and has pioneered the development of better health assessment and education tools for the past two decades. Dr. Mark’s passion is to contribute to the development of the tools and systems that empower people to become more health-responsible and to champion their personal health and vitality.
As one of Complimentary and Alternative Medicines most respected advocates, his international audiences have included thousands of health practitioners and members of the public throughout Canada, United States and Australia. For the past eight years, he has been dedicated to the development of the web-based systems and virtual community that enable healthcare consumers to understand their personal needs more clearly and to meet these needs simply and directly.
Dr. Percival is dual licensed as a doctor of Naturopathic Medicine and a doctor of Chiropractic and continues to run an active practice one 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 valuable health promoting resources. His unique experience gleaned from three decades of clinical experience, with thousands of patients, forms the foundation of our highly regarded e-course: Real Freedom, The Mind-Body-Stress Connection.
To quote Dr. Percival: “Direct Access eHealth represents a new phase in health care delivery, one which moves well beyond our earlier work at Health Coach® and incorporates new technology that enables all to benefit directly from the age-old truism: We are smarter and more capable then Me.”

Dr. Gregory Kelly leads our Research and Development Department. A growing number of health professionals consider Gregory to be the preeminent thinker in the field of integrative healthcare and in the understanding of functional human physiology. His seminal work on the emerging field of shape intelligence is the best example of his progressive understandings. Gregory teamed up with Dr. Percival and Dr. Richard Perryman to build better healthcare systems almost 10 years ago. After contributing to the development of several iterations of IT platforms, intended to solve for some of the more significant gaps in our conventional healthcare systems, they decided to team up with Dr. David Haase and co-develop their own system at Direct Access eHealth.
Gregory 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 contributed three chapters to the Textbook of Natural Medicine, 2nd edition, by Murray and Pizzorno (published by Churchill Livingstone, 1999).
Dr. Kelly is a doctor of Naturopathic Medicine and has taught courses on Advanced Nutrition, Doctor/Patient Relationships and Counselling at the University of Bridgeport, College of Naturopathic Medicine, and Sports Nutrition at Southwest College of Naturopathic Medicine and Health Sciences.
With his strong research background, Dr. Kelly ensures that Direct Access eHealth incorporates the most effective, science-based, health assessment and education systems available to improve the healthcare decisions of our customers.

Dr. Richard Perryman joined Dr. Percival and the Health Coach® team in 1994. He immediately saw the need to bring their evolving assessment and education applications to the corporate wellness marketplace and created the Health Coach Corporate Wellness Center of Phoenix. The center became a proving ground for the many technologies being developed at Health Coach®. The practical experience gained, led to a growing awareness of what was required to stem the tide of escalating chronic illness and associated costs. This led to Dr. Rick’s co-founding of a new company, LifeStrive, in 2005, followed by Direct Access Labs in 2007, and Direct Access eHealth in 2008. The focus of each company (working in tandem) is to enable the delivery of key services to corporate America, and assist their employees in becoming more health-responsible and reaping the many benefits.
Dr. Perryman and the entire Direct Access eHealth team believe shifting to a more collaborative, health promoting, education focused and self-responsible healthcare model, is not only logical, but is now driven by market forces that make it inevitable. Corporate America is clearly the single largest stakeholder in healthcare today.
