Chisholm John DPM holds California podiatry license E3431 and has practiced in Chula Vista since co-founding South Bay Foot & Ankle Specialists on F Street in 1990, now operating within the Upperline Health podiatry network with hospital privileges at Scripps Mercy Hospital San Diego and Sharp Coronado Hospital. The practice's biomechanical evaluation protocols for gait abnormalities and lower-extremity alignment complement the spinal and postural assessments performed at Wachs Chiropractic Health Center, addressing the kinetic chain from lumbar spine through foot strike for patients with compensatory movement patterns. Surgical and conservative podiatric services span bunionectomy, hammertoe correction, plantar fasciitis release, diabetic wound debridement, and custom orthotic fabrication from plaster-cast molds taken at the F Street office. Chronic foot pain management draws on complementary modalities including the needle-based approaches at South Bay Family Acupuncture for patients with peripheral neuropathy or recalcitrant plantar heel syndrome. The facility specializes in Lapiplasty 3D bunion correction and minimally invasive percutaneous Achilles tendon repair using the Arthrex PARS jig system to restore tendon continuity through a sub-centimeter incision.
