Growing older brings wisdom, perspective, and a lifetime of stories. It can also bring new health questions: a growing list of medications, a diagnosis or two to keep track of, a fall that shook your confidence, or a memory lapse that left you or someone you love wondering, “Is this normal?”
Those questions deserve a doctor who specializes in answering them. That is why San Antonio Regional Hospital created the Geriatrics Clinic at our new Lewis Center of Aging in Rancho Cucamonga, a place designed from the ground up for older adults and the families who care for them.
Meet Dr. Ecler Jaqua
Ecler E. Jaqua, MD, MBA, FAAFP, AGSF, FACLM, DABOM, AAHIVS, serves as Medical Director of the SARH Lewis Center of Aging. She is an Associate Professor of Family and Geriatric Medicine and Program Director of the OPTI-West SARH Family Medicine Residency, where she trains the next generation of physicians.
Dr. Jaqua’s path to geriatrics began early. Originally from Brazil, she entered medical school at seventeen at The Lutheran University of Brazil, drawn by a lifelong passion for caring for people at every stage of life. She completed her Family Medicine residency at Loma Linda University Health, serving as Chief Resident in her final year, and then completed a fellowship in Geriatric Medicine at the University of California, Los Angeles (UCLA).
She is board certified in four specialties: Family Medicine, Geriatric Medicine, Lifestyle Medicine, and Obesity Medicine. She also holds a Master of Business Administration in Strategic Leadership, is a certified Lifestyle Medicine Intensivist, and is a credentialed HIV Specialist. Her Fellow designations from the American Academy of Family Physicians (FAAFP), the American Geriatrics Society (AGSF), and the American College of Lifestyle Medicine (FACLM) reflect recognition by her peers across each of these fields.
What patients notice first, though, is her energy. Dr. Jaqua is known around campus for her warmth and enthusiasm, and, on most days, for singing along to her favorite music as she drives between buildings. Outside the clinic she enjoys reading, hiking, traveling, and playing volleyball with her husband and their daughter, Celine.
Her passion is healthy aging: helping older adults stay active, independent, and connected to the people and activities they love, and building “age-friendly” care in every setting, from the exam room to the wider community.
A Leader in Her Field
Dr. Jaqua is frequently invited to teach other physicians. In 2026 alone she was a featured speaker for the Riverside-San Bernardino Chapter of the California Academy of Family Physicians, co-presented on blood-based biomarkers for Alzheimer’s diagnosis at the American College of Osteopathic Family Physicians of California’s 50th Annual Convention, and presented on evidence-based obesity care at the CAFP Population Health & Obesity Conference. The same expertise she shares with colleagues statewide is available to patients right here in Rancho Cucamonga.
