Tracey L. Norton, DO – Family Medicine Residency - Program Director

Dr. Norton was born in Ventura, California the eldest of 5 children and raised in a family that moved every two years as her engineer father followed the petroleum industry around the world. She spent years in Lima, Peru and Buenos Aires, Argentina, returning to the United States as a bilingual bicultural teen.

Dr. Norton received her Doctor of Osteopathic Medicine from Kirksville College of Osteopathic Medicine and completed a transitional internship year in Columbus, Ohio. Having financed medical school with a Uniformed Services Health Professions Scholarship from the US Public Health Service (US PHS), she decided to complete her service obligation as a general medical officer in the Indian Health Service.

Dr. Norton moved to rural Northeast Arizona for four years and provided full scope primary care medical services to people and families from the Navajo Nation and Hopi Tribe. At one point the US PHS sent her to Fort Smith, Arkansas on temporary duty assignment with other Spanish-speaking personnel to provide medical services to Cuban refugees during the Mariel Boatlift.

From Arizona she returned to Southern California to complete family medicine training at the USC/California Hospital Family Medicine Residency Program where she was chief resident. After residency she worked a summer in Nome, Alaska caring for Alaska Natives – the Inupiat.

Back in Los Angeles Dr. Norton worked as core family medicine residency faculty in area programs for nine years. She attended a faculty development fellowship at USC and focused on development and implementation of Women’s Health and Maternity curricula. She and a colleague provided medical services to one of the early residential Hospices in Hollywood. She made presentations to the medical staff on the vertical transmission of HIV in the early years of the HIV epidemic.

During the next decade, Dr. Norton started and directed a university-sponsored family medicine residency program at USC Keck School of Medicine. Ten classes completed training over the next 12 years.

Dr. Norton departed academic medicine to return to her rural medicine roots, working with two other family physicians and a nurse practitioner in a rural health center and critical access hospital on Catalina Island.

She returns to graduate medical education through the visionary commitment of Citrus Valley Health Partners and East Valley Community Health Center to collaborate and build a residency where physicians are inspired to develop expertise in family medicine and to dedicate themselves to the care of individuals, families, and communities especially those who are underserved.

Chinhnam Hathuc, DO – East Valley Community Health Center – Chief Medical Officer

Chinhnam Hathuc, D.O. was born and raised in Southern California where he lived with his family in the Inland Valley. At the age of 16, he received a scholarship and left home to attend Simon’s Rock College of Bard in Great Barrington, Massachusetts. He graduated college at 19 years old and took a research position at the University of Minnesota, Twin Cities. After two years of Neuroscience research, and a good amount of soul-searching, he decided to pursue a career in medicine and attended Touro University in Northern California.

Dr. Hathuc had the opportunity to share his medical school experience with his brother, as they were housemates and schoolmates. When not studying for exams, they both spent their summers volunteering for Camp Footprints – a non-profit organization that serves physically, mentally, and/or socially economically challenged children. Volunteering at Camp Footprints is still a passion for both of them to this day.

After graduating medical school, Dr. Hathuc returned home to Southern California and completed his Family Medicine residency at Pacific Hospital in Long Beach, California. During his residency program, he developed a passion for community medicine as he worked in a medically underserved area. He wanted to put his efforts into community medicine because he saw a great need for quality health care for those patients that are most vulnerable.

Upon completion of his residency program and board certification in Family Medicine, Dr. Hathuc joined East Valley Community Health Center- a federally qualified health center that serves the San Gabriel and Pomona Valleys. He works there as a Lead Physician and the Chief Medical Officer for their four community clinics. He is also an Attending Physician and the Osteopathic Medicine Director for the Family Medicine residency program at College Hospital in Long Beach, California.

Through the partnership between East Valley Community Health Centers and Citrus Valley Health Partners, Dr. Hathuc hopes to give back to the communities that helped shape his career and inspire future Family Medicine physicians to go into community medicine.
