Dr. David Gordon, M.D.

Dr. David Gordon has spent his entire career helping patients create health. Early on, he realized that blindly following his conventional training and using prescription medication was not making patients feel better or become healthier. From that point on, he has dedicated himself to understanding what creates optimal health and finding the safest, and most effects methods to achieve that goal. He owned, operated, and managed a private primary care clinic for 15 years passing that knowledge on to patients as their educator, mentor and guide. During his time in practice, he witnessed the safety and effectiveness that medical cannabis offered to patients and is excited to be on the forefront of cannabis medicine, bringing that knowledge to patients.

Dr. Gordon received his Medical Doctorate and Residency training at the University of Colorado. He is board-certified in Internal and Integrative Medicine and is a Certified Functional Medicine Practitioner through the Institute for Functional Medicine.

4 key pillars — food, movement, relaxation and community — are the cornerstones to achieving optimal health. Dr. Gordon believes that learning about and incorporating these pillars are the path to control your own destiny, understand the root causes of your illness, and distance yourself from a dysfunctional system that stresses drugs and procedures at the expense of true health. When not working to achieve optimal health in others, Dr. Gordon brings those same philosophies to his personal life alongside his wife, two teenagers, and his dog Dexter. He has an active meditation practice and believes that is crucial for balancing the onslaught on information, toxins, and technology to which we are exposed. On days off, you’ll find him playing tennis, riding his bike, or getting out into nature. Cooking and traveling are also things he and his family enjoy.
