Serotonin

What Serotonin does

Serotonin Centers (legal entity Serotonin Enterprises LLC, dba Serotonin Anti-Aging Centers) is a Florida-domiciled, privately held franchise system that operates physician-led longevity and medical wellness clinics across the United States. The company was founded in 2021 (per firmographic data) and is led by CEO Eric Casaburi. The offering is organized around four service pillars: hormone optimization (including bioidentical hormone replacement therapy, testosterone therapy, and female HRT), medical weight management (including GLP-1 prescription protocols, CoolSculpting, and EMSCULPT NEO), aesthetic enhancement (BOTOX, dermal fillers, HydraFacial, microneedling, hair restoration, Sculptra, and body contouring), and wellness therapies (IV therapy, hyperbaric oxygen, red light, NAD+, and peptide therapy). Underpinning the service menu is SeroVitals360, a branded diagnostics platform that combines hormone testing, metabolic analysis, and InBody body composition scanning to drive personalized treatment plans, plus the Serotonin Coach App (built on Trainerize) and Serotonin Booking App (built on Zenoti), and a proprietary Serotonin Nutraceuticals supplement line.

The company generates revenue through three streams: (1) franchise development fees and ongoing royalties from individual and multi-unit franchise owners, with a stated target of 100+ locations within three years; (2) clinical services revenue captured at franchise-operated locations on a membership-style recurring treatment model; and (3) a Serotonin Partner Program launched in March 2026 that installs 200-500 square foot turnkey longevity suites inside third-party fitness facilities, where Serotonin handles clinical operations, compliance, and care delivery while gym operators provide physical space. Franchisee development is anchored by physician-led multi-unit groups, most notably LifeHub Center LLC (up to 18 units across Miami-Dade, Broward, and Palm Beach Counties) and AgeWell Longevity LLC (five units across Dallas and Collin County). As of early-to-mid 2026 the company has 15 or more operating locations across Florida, New Jersey, Tennessee, Missouri, South Carolina, Connecticut, Texas, and Illinois, with stated coverage across the Southeast, Southwest, Midwest, and Northeast U.S. Operating support is delivered through a proprietary 5-Day Live Training Program that combines classroom didactic training with two "Confidence Days" at a live operating center, designed to enforce consistency across the franchise network. Recognition includes Entrepreneur Magazine's Franchise 500 and Top New & Emerging Franchises lists for 2025 and BeautyMatter profiling among the fastest-growing medspa franchises. Capital structure includes a $6.5M funding round from Anti-Aging Holdings Orlando in June 2022; no venture, growth equity, or institutional investor disclosures are present in the input data.
