Her drive and devotion is to enhance her patients’ quality of life for decades to come. Drawing from her own personal experience with health challenges, and her confidence that treating each patient as a unique person that is striving for optimal health, instead of addressing just their medical diagnoses and symptoms, is a far better approach to health care.

She then studied medicine and received her Osteopathic Medical Degree at Midwestern University in Glendale, Arizona in 2006.

Dr. Forbes is also a member of Adaptive Cancer Care Essentials Program which is a highly esteemed, prolific and dynamic integrative cancer care training program.
Dr. Tarin Forbes believes that the best doctors are not only teachers and mentors, but are also leaders that are willing to walk the walk to health and not just advise others to do so. Everything we do is geared towards inspiring patients to live a vibrant life and restoring health using a very personalized medical approach. Her special medical interests lie in optimizing cognitive function and memory, cardiovascular health and fitness, bio-identical hormones and sexual health, and integrative cancer support and prevention.

“I’m extremely happy with Dr. Kyle. He made me feel comfortable talking with him about any of my questions or health concerns, including female concerns. I’m very pleased with the amount of time spent going through bloodwork and any other questions I had.
He’s extremely knowledgeable, professional, and explains everything thoroughly in terms I can understand. Very happy to have found a new doctor that I can trust!”
