The Maas Clinic is a private facial plastic and aesthetic surgery practice founded by Dr. Corey S. Maas and headquartered on Clay Street in San Francisco. The clinic offers a full spectrum of surgical facial procedures (facelifts, rhinoplasty, eyelid surgery, brow lifts, facial fat transfer), breast procedures (augmentation, lift, reduction, reconstruction), body contouring (liposuction, tummy tucks, mommy makeovers, arm and thigh lifts), hair restoration (NeoGraft FUE, PRP, exosome therapy), and a broad non-surgical offering that includes neuromodulators (Botox, Dysport, Xeomin, Jeuveau, Daxxify), dermal fillers, lasers, microneedling, RF treatments, Ultherapy, Sofwave, and body sculpting technologies (CoolSculpting, CoolTone, UltraShape, VelaShape, Cellfina, Aveli, Renuvion, miraDry).

The practice operates through an integrated three-facility campus: the main clinic at 2400 Clay Street, the Appearance Care Center medical day spa at 2408 Clay Street, and the San Francisco Rejuvenation Center, a fully accredited ambulatory outpatient surgery center at 2402 Clay Street, with advanced anesthesia capability (TIVA and MDSA). It maintains an in-house Research Center that conducts FDA and non-FDA clinical trials on emerging aesthetic technologies, a tele-consultation platform with digital morphing for remote patient evaluation, and concierge recovery services including Clay Street and Tiburon Oasis apartments for traveling patients.

Revenue is generated through consultation-based pricing on surgical procedures, recurring or one-time non-surgical treatments, a monthly subscription GLP-1 weight loss program, proprietary skincare product sales via e-commerce and in-clinic, and post-surgical concierge services. The customer base consists of affluent individual consumers seeking premium aesthetic care, including national and international traveling patients, with pricing not publicly disclosed and financing options available. The firm is privately held by Dr. Maas with no external investment, parent company, or M&A activity evidenced.

Broad incumbents

• Sono Bello: Largest US body-contouring and cosmetic surgery chain with national clinic footprint. Overlap with Maas Clinic's body contouring, liposuction, and tummy tuck offerings, but operates a high-volume, standardized model compared to Maas's bespoke surgeon-led offering.
• SkinSpirit: Bay Area-headquartered luxury medical spa chain offering injectables, lasers, and body treatments under medical direction. Direct regional competitor to The Appearance Care Center for non-surgical aesthetic services across the Bay Area.
• Ideal Image: Largest US medspa chain focused on laser hair removal, injectables, and body contouring. Overlaps with Maas Clinic's non-surgical injectables, CoolSculpting/CoolTone, and laser offerings but competes on access and financing rather than surgeon-led personalization.
• Schweiger Dermatology Group: Multi-location dermatology group in the Northeast US with extensive medical and cosmetic dermatology including injectables, lasers, and body treatments. Comparable integrated clinical-and-cosmetic offerings against a multi-site operating model.

Emerging players

• LaserAway: Fast-growing medspa chain focused on laser hair removal, body contouring, and aesthetic treatments, primarily in California. Overlaps with Maas Clinic's laser hair removal, CoolSculpting, and non-surgical services, positioned as a high-access, marketing-heavy alternative.
• Skin Laundry: Rapidly expanding membership-based medspa chain known for laser facials and skin treatments. Adjacent to The Appearance Care Center's laser and skin rejuvenation offerings on price and accessibility rather than surgeon-led service.
