What Function Physical Therapy does
Function Physical Therapy is a single-location, founder-owned private physical therapy practice based in Brentwood, Los Angeles, California. Founded and operated by Dr. Jonathan Casler, PT, DPT, OCS — a board-certified orthopedic specialist with 20-plus years of clinical experience — the practice delivers manual orthopedic and sports physical therapy to patients across the West Los Angeles submarkets of Brentwood, Santa Monica, Westwood, and West Los Angeles. It serves three primary patient cohorts: competitive and recreational athletes requiring sport-specific rehabilitation, post-operative orthopedic patients recovering from procedures such as rotator cuff repair, ACL reconstruction, and joint replacement, and individuals with general musculoskeletal conditions including sprains, strains, bursitis, and spinal disorders.
The clinical model rests on one-on-one private treatment sessions with the same physical therapist across the care episode. Treatment combines hands-on manual therapy with rehabilitation equipment including Vectra Genisys modality systems, FreeMotion resistive equipment, and frame-by-frame video analysis for biomechanical assessment. Adjacent offerings include custom-cast foot orthotics based on gait and running analysis, preventative spinal care, and educational resources (downloadable injury-specific PDFs hosted on the website). All services are delivered in-person at the Comerica Bank Building location, with extended weekday hours of 7 a.m. to 7:30 p.m.
Revenue is generated on a fee-for-service professional services basis. The practice is in-network with 80+ PPO insurance plans, accepts Medicare Part B and Workers' Compensation cases, and bills insurers directly; out-of-pocket or cash-pay arrangements also exist. Patient acquisition flows through the website, word-of-mouth, physician referrals, and orthopedic surgical group referrals, with brand presence limited to a content-driven website, Facebook, and Twitter. The firm has no external investors, no funding history, no patents, and no strategic partnerships disclosed in the source materials.
