Mark Mansfield, MD

“When I was seven I studied the anatomy and the layers of the human body in the Encyclopedia Britannica; remember those clear pages?” At a young age, Dr. Mansfield fell in love with the sciences and developed a hunger for unbiased answers; “We call that evidence based, outcome oriented medicine in Family Medicine”, he explains.  “At age ten I thought my family doctor was amazing for fixing my sore throat. He was wearing a white coat, and I remember wanting to be like that; I wanted to be a professional. At age fifteen he set my broken hand in the ER which hurt so badly when he set it and then he placed me into a cast. I wanted to fix people who needed fixing.”

Dr. Mansfield is extremely detail oriented. He is expert at sitting down and going over all of his patient’s medications and health history to provide a more accurate and tighter controlled diagnosis. “Patients say I take their illness very personally, and it is true. I engage with the patients and their story and do my absolute best to help them.” Dr. Mansfield is also involved in local sports as a coach for wrestling and soccer. He admits his competitive nature carries over into his practice, “I can be pretty intense with my patients sometimes, like a coach.”

Dr. Mansfield is married and has three children. Originally from a small town in Nevada, Dr. Mansfield wanted to move to Idaho because of the family focused environment and his love for the outdoors. Because of this, he did his residency at Idaho State University. Dr. Mansfield is Board Certified in Family Medicine and has been on the medical staff at Portneuf Medical Center since 1997.  He is an Associate Faculty member at Idaho State University’s Family Practice Residency as well as the Physician Assistant Program. He holds an Associates in Math and Science from Lassen College, a Bachelors of Arts in Zoology from Arizona State University and a Medical Doctorate from the University of Nevada Reno.

Richard Maynard, DO, FAAFP

“A cowboy, an astronaut, or a doctor”- those were the careers Dr. Maynard was considering as a child. From the age of 3, Dr. Maynard was considering a career in medicine. Dr. Maynard has now been a Family Practice physician in Pocatello for over 2 decades and yet he is still always looking for ways to learn and find solutions to help his patients with their healthcare needs.

He feels everyone deserves quality care that is evidence based. Keeping up to date on the latest and most effective treatments and guidelines for patient health is a top priority for him. Even patients who see one of the experienced Physician Assistants or Nurse Practitioners at the office will get a chart review from Dr. Maynard. Even though it isn’t required, he feels every patient deserves a personal review of their care by their physician.

What guides Dr. Maynard is a strong sense of family, not just with his own wife and nine children, but with his staff and all his patients. Being family oriented gives him an empathy in his practice. He understands the concerns his patients may have and works to help them feel comfortable and encourages them to take an active part in their medical care.

Dr. Maynard believes in being proactive when it comes to treating his patients. He says medication isn’t always the answer and he believes strongly in encouraging his patients to seek a healthy lifestyle. “I help my patients set goals and when I see them reach those goals that is really rewarding.”

Dr. Maynard has a Bachelor of Science degree from Idaho State University and graduated from the University of Osteopathic Medicine and Health Sciences, College of Osteopathic Medicine and Surgery in Des Moines, IA. He completed a residency in Family Medicine at Oregon Health Sciences University in Portland, Oregon. He is Board Certified in Family Medicine. Dr. Maynard is a Fellow of the American Academy of Family Physicians.
