Dr. Hans Ewertz earned his DVM from the University of California, Davis in 1976 and has practiced his entire 49-year career at the same 3767 Voltaire Street hospital, making him the longest-tenured veterinarian in the Point Loma-OB corridor. His caseload leans toward the generational OB families whose parents and grandparents brought pets to the same exam rooms, producing long-relationship preventive medicine with a deep baseline on each patient, and senior-pet Rx diets and long-term medications are filled at Point Loma Pet Pantry when clients prefer to pick up outside the hospital. Services include physical exams, vaccinations, spay and neuter, dental care, soft-tissue surgery, digital radiography, and in-house laboratory work for cats and dogs of all life stages. Dr. Ewertz is a surfer and gardener in his off-hours, practical context for the chronic-pain, arthritis, and coastal-allergen cases that come through his door. For terminal-diagnosis patients whose families want the final visit to happen at home rather than in an exam room, referrals move to Dr. Dawn Ziegler at Home Sweet Home Veterinary Housecalls. The most complex work Dr. Ewertz handles is multi-decade geriatric management — the same cat or dog seen from eight-week puppy visit through senior-wellness monitoring, renal staging, cognitive decline, and end-of-life decision-making with an owner he has known since before the pet was born.
