What PortmanDentex does

PortmanDentex is a privately held dental care group formed in 2022 through the merger of Portman Dental Care and Dentex Health. It operates 370+ dental practices across the United Kingdom and the Republic of Ireland, employing 1,200+ full-time staff alongside 2,000+ self-employed dental consultants and specialists. The group serves over one million patients annually, delivering general dentistry, cosmetic procedures, orthodontics, dental implants, and specialist treatments through a combination of owned and partner-led practices. Headquartered in Cheltenham, Gloucestershire, the company is led by Group CEO Paul Marshall and Founder & Chairman Sam Waley-Cohen, with a central support function ("The Port") handling Finance, People, Marketing, Business Development, Commercial Contracts, Estates, Compliance, Learning, and Strategic Operations across UK subsidiaries (Portman Healthcare Limited, Dentex Healthcare Group Limited, Dentex Clinical Limited, Dentex Assets Limited) and Irish entities (Portman Healthcare Holdings (Ireland) Limited, Portman Healthcare Midco (Ireland) Limited, Portman Healthcare (Ireland) Limited).

The company's product surface combines patient-facing care with a clinician-facing partnership platform. Patient offerings include tiered consultation fees (free with refundable deposit up to £75), pay-as-you-go treatment pricing, and third-party patient financing through Product Partnerships, Secure Trust Bank, and V12. For dental clinicians and independent practice owners, the group runs four structured partnership tracks: Selling Your Practice, Joint Venture Partnership, Shared Ownership Programme, and Succession planning. Internally, two network-wide products anchor cross-practice value: the Clear Aligner Programme, which standardizes clinical governance for aligner treatments, and The Referral Hub, an internal platform enabling clinicians to refer patients to specialists across the network. Clinical training and Practice Clinical Lead roles support ongoing workforce development.

Revenue is generated primarily from private dental care services delivered through the practice network, with the dual customer base — individual patients and clinician/practice partners — creating two distinct go-to-market motions. Geographic clustering is notable in London (38 practices) and Manchester (9 practices), with additional footprint across the UK and Ireland. The December 2024 Leadership Conference introduced a "Better Not Bigger" strategic vision alongside a reported 9% group growth figure, signaling a shift in emphasis from pure practice-count expansion toward operational depth and clinical quality. The company holds no public ticker and does not disclose revenue.
