CLS Health

What CLS Health does

CLS Health is a physician-owned and physician-led multi-specialty healthcare group headquartered in Webster, Texas, serving patients throughout the Greater Houston market. The organization operates 45+ clinic locations and is staffed by 300+ providers across 40+ medical specialties, delivering primary care together with specialty services including Pediatrics, OB/GYN, Cardiology, Eye Care, Podiatry, Urology, Sleep Medicine, Nephrology, Plastic Surgery, Dermatology, Bariatric Surgery, and Colon and Rectal Surgery. Flagship facilities such as the Clear Lake site co-locate imaging, laboratory, infusion, optical, pharmacy, and surgical services, supporting a one-stop-shop care model. The group reports serving 100,000+ Houstonians annually and accepts 80+ health insurance plans including Aetna, Blue Cross Blue Shield, Cigna, and UnitedHealthcare. The company was founded in 2005 by Mohammad J. Baba, MD and Mahmood Dweik, MD as Clear Lake Pulmonary, transitioned through Clear Lake Specialties, and rebranded to CLS Health, celebrating its 20th anniversary in 2025.

The underlying technology layer centers on the third-party Healow Patient Portal (eClinicalWeb), which provides 24/7 access to records, online appointment scheduling, secure messaging with the care team, and test-result delivery. CLS Health supplements the portal with a provider search tool, a content-driven health blog with provider-authored articles, an email newsletter, and a centralized Contact Center. The group's go-to-market is direct-to-consumer across the Greater Houston region, with patients accessing care via scheduled appointments (online or by phone), same-day slots, or walk-ins, complemented by physician referrals and community-based healthcare networking. The revenue model is fee-for-service patient care billed through insurance claims and patient payments, with deductibles, co-pays, and coinsurance determined by each patient's plan; specific service pricing is set at the point of care and cost estimates are provided on request.

In July 2024 CLS Health executed a merger with Campbell Family Practice and Ghebranious Internal Medicine Associates, lifting the network above 35 locations and adding 35+ primary care providers, and has continued opening clinics in Katy, Conroe, and Pearland through 2024. Leadership includes CEO Megan Owen, MBA (since 2023), COO Misty Berger, MBA, and founders Dr. Baba (President) and Dr. Dweik (Vice President). Ownership is described as physician-partnership with equity, voting rights, and a defined share-buyout exit; no external private-equity or institutional investor ownership is indicated. The company remains private and has no disclosed funding rounds.
