Proctos Kliniek

What Proctos Kliniek does

Proctos Kliniek (legal entity: Stichting Proctos Klinieken) is a Dutch private specialist medical clinic founded in 2010 by Charlotte Molenaar, treating proctological and pelvic floor disorders in adults aged 18 and older. The clinic operates three consultation and minor-procedure locations (Bilthoven, Amsterdam, Rotterdam) plus two surgical operation facilities (Vlaardingen, Bosch en Duin), with a multidisciplinary team of surgeons, pelvic floor physiotherapists, medical psychologists, dermatologists, and continence nurses totaling 45+ staff. Core clinical capabilities include endo-anal ultrasound, transperineal ultrasound, 3D high-resolution anorectal manometry, and defecography, supported by digital infrastructure including a new Electronic Patient Record (December 2025), a Personal Health Environment integration via Quli, the AI chatbot Charlie, and Zivver secure communications.

The clinic generates revenue through Dutch DBC (Diagnose-Behandel Combinatie) billing under contracts with all Dutch health insurers; patients pay only the mandatory deductible (€385 for 2023–2025). Uninsured patients access services at published passantentarieven. Go-to-market is referral-driven via the ZorgDomein electronic referral system used by general practitioners and specialists in gynecology, urology, and gastroenterology, complemented by a community-led professional outreach program through Proctos Academy (accredited courses, workshops, ultrasound training with GE Healthcare and BK Medical, and a podcast). Supporting commercial activities include the Empowered Relief pain program (2024), medical psychology consultations, pelvic floor physiotherapy, continence nursing, and awareness campaigns such as 'Praat Poep Met Me' in partnership with Coloplast.

The clinic holds the ZKN-kwaliteitskeurmerk since October 2012, is a member of the Defecatie Expertise Centrum (DEC) network, and maintains an active scientific research program with 15+ peer-reviewed publications per year, three completed PhD dissertations (2023–2025), and ZonMw-funded multicenter trials (ATLAS, LA POPA, CRAFT, THROS). Patient-reported satisfaction stands at 9.1/10 across 1,012 ZorgkaartNederland ratings. The clinic is privately held with no external investors or parent company, operating as a self-governing Stichting under founder Charlotte Molenaar's direction.

Scale indicators7 records

Recent moves10 records

Expansion highlights5 records

Broad incumbents

• Stichting Spaarne Gasthuis: Large Dutch hospital with a coloproctology department offering proctological services as part of a broader general hospital portfolio. Competes for proctology referrals but as part of a much wider service mix rather than a specialized niche.
• Amsterdam UMC: Academic medical center with a Department of Surgery (Prof. Bemelman supervises Proctos PhDs) and colorectal services. Functions as a research partner but also as a competitor for complex colorectal referrals in the greater Amsterdam region.
• Cleveland Clinic: Global leader in colorectal surgery with dedicated subspecialty expertise, multidisciplinary teams, and a strong research footprint. Comparable in the depth of its proctology/colorectal offering and academic output, though as part of a much broader health system.
• St. Mark's Hospital (London North West University Healthcare): Historic UK specialist centre for coloproctology and intestinal disease, offering a benchmark for what a deeply specialized proctology institution looks like at international scale. Comparable in clinical focus but operates within the NHS.

Direct peers

• Equipe Zorgbedrijven: Dutch operator of independent specialist clinics (orthopedics, ophthalmology, dermatology, etc.) with insurer contracts across the Netherlands. Closely comparable business model and regulatory environment to Proctos.
• Bergman Clinics: Major Dutch chain of independent specialist clinics offering focused outpatient and surgical care across multiple specialties (including Vrouwenzorg/urogynaecology referenced as a Proctos partner). Most directly comparable as a Dutch independent clinic operator with insurer contracts and a multi-site footprint.
• DC Klinieken: Dutch network of independent treatment clinics (Diagnostisch Centrum) offering focused specialty care with health insurer contracts. Operates under the same ZKN quality framework as Proctos and competes for the same Dutch independent-clinic patient pool.

Others

• Hollister Incorporated: Continence care and ostomy device manufacturer serving anorectal patient populations. Adjacent to Proctos through shared patient demographic rather than direct service competition.
• Convatec: Medical products company serving patients with chronic conditions including continence care and ostomy. Adjacent ecosystem player to Proctos' patient population rather than a direct clinical competitor.
• Coloplast: Global medical device company focused on ostomy, continence, and wound care. Partnered with Proctos on the 'Praat Poep Met Me' awareness campaign and serves many of the same patient populations through ostomy and continence products.
