Tasha King

Medical Assistant

Tasha was adopted from Russia as an infant by her outstandingly caring family, and they moved to Colorado in her early years. After high school, she moved to Grand Junction, CO and graduated from Colorado Mesa University (CMU) with a Bachelor of Science in Exercise Science in 2018. While finishing her studies, she received her Phlebotomy Certification, from the American Society of Clinical Pathology through CMU.

During her days at CMU, she spent her free time hiking the mesas with her Australian Shepherd, volunteering, and spending time with her friends and family.

After college Tasha worked in a Physical Therapy clinic where she was constantly in contact with insurance companies. Through her work, she realized the need for Direct Primary Care (DPC) models, such as Mint Health Clinics Lone Tree, to simplify the unnecessarily complicated system and ease the financial pressure that goes hand-in-hand with healthcare. She believes that healthcare should be effective, efficient, and accessible to all and is excited to be a part of a clinic that shares the sentiment.

Shawn Stephens

Business Director

Shawn grew up in Grand Junction, CO, and graduated from Colorado State University with a B.S. in Business Administration. After college, he moved to Seattle, looking for an adventure. During the nearly 10 years he lived there, Shawn loved exploring the water and mountains (where it actually sometimes rained while he skied), worked as a technical consultant for Microsoft, met his wonderful wife Amy, and had his first son. In 2005, Shawn and Amy moved to Colorado to be closer to their families. Soon thereafter they had their second son, and have called Colorado home ever since.

Like most of us, Shawn’s family has experienced the hassles and frustrations of dealing with the traditional fee-for-service healthcare model. The problem is, they just dealt with it, because that’s “just the way things are”. But after spending several years caring for his father and trying to navigate the unnecessarily complex healthcare system, he knew there had to be a better way. There had to be a way to make healthcare more efficient and effective for both physicians and patients. He landed on direct primary care healthcare, and knew immediately it would be the game-changing model that would provide a superior healthcare experience.

Robert Boyer, MD

Chief Medical Officer

Dr. Boyer received his Medical Doctorate at the David Geffen School of Medicine at UCLA. Dr. Boyer has a passion for improving healthcare in America. After a short time practicing for a hospital system, based in the fee-for-service insurance model, Dr. Boyer knew there had to be a better way. With a passion for removing as many barriers between physicians and patients,  he made the financial leap into membership-based healthcare. Dr. Boyer has found owning his own business to be challenging and extremely gratifying. He and his fellow physicians love practicing medicine, their way, and now they find themselves trying to keep up with the patient growth from families, businesses, and governmental entities who love the affordable cost and the access to care.
