Since he was a child, Dr. Fitchmun wanted to be a doctor. Now that he has been in practice for 14 years, he still looks forward to every new work day. Dr. Fitchmun believes that to diagnose and treat patients effectively, a doctor must not only have excellent examination skills but must also take time to listen compassionately and attentively. The best outcomes happen when patients actively participate in maintaining their good health, preventing illness, and controlling disease. To do that, he provides patients with solid medical information and treatment plans that are aligned with their needs and goals so they can make the best possible health care choices.
In 1993, Dr. Fitchmun graduated from UC Berkeley with honors and then attended UC Davis School of Medicine with a Regents Scholarship. After completing his residency in 2002, he joined Arroyo Medical Group and currently serves as medical director. He maintains board certification in Family Medicine, and is an active member of The American Academy of Family Physicians and the California Academy of Family Physicians. His areas of expertise include:

Originally from Spokane, Washington, he grew up in Santa Clara, California. He attended Stanford University, earning a Bachelor of Science degree in 1979. With a number of career choices before him, and with the influences of the lives of important mentors in his life, he chose to pursue a career in Medicine. He was admitted to the California College of Medicine at UC Irvine, and graduated in 1984. The many experiences in medical school, covering all medical specialties, prompted him to choose to enter Family Medicine. He entered the Family Practice residency at UC Davis Medical Center in Sacramento in 1984.
With the guidance of some remarkable physicians over these years, he developed a deep commitment to the concept of ongoing doctor-patient relationship, with emphasis on preventive medicine, and personalized care in promoting wellness, as well as in treating disease.
He and his wife, Debbie, have been married for over 30 years, and count their two grown sons as their greatest blessings. They both had the privilege of growing up in this town and attending Cal Poly in their chosen fields of software engineering and graphic communications.
Now, after almost three decades of the practice of Family Medicine, he has the privilege of living and working in this beautiful part of California, with a group of physicians and staff that share the same strong desire to give every one of his patients the attentive and highly competent care that he would want for his own loved ones. It is the daily aim of everyone at Arroyo Medical Group to reach that goal.
