About
At Pasteur Medical Associates, seven board-certified internal medicine physicians deliver comprehensive, coordinated care to adults in San Antonio, Texas. Dr. Bradley Kayser founded the practice in 1993 and grew it over three decades into a seven-doctor team. PMA recently marked 30 years as an independently owned organization. The practice operates a hybrid model, pairing traditional insurance-based care with a concierge membership tier. Every patient at PMA sees a board-certified internist. The practice never uses midlevel providers. Its in-house laboratory holds COLA and CLIA accreditation dating to 1992 and has earned the COLA Laboratory Excellence Award multiple times. The practice also operates a GE Lunar Prodigy Advance DEXA scanner with Trabecular Bone Scan capability, in-house digital X-ray, and advanced cardiovascular screening including carotid intimal media artery thickness exams. Each physician works in a dedicated section of the office, giving patients privacy and efficient care. The team coordinates closely with the Methodist Healthcare System and manages specialty referrals for patients who see multiple providers.
