Veterinary Specialty Services

What Veterinary Specialty Services does

Veterinary Specialty Services (VSS) is a privately-owned, multi-specialty referral and 24-hour emergency veterinary hospital operating two locations in Missouri — its Manchester headquarters (1021 Howard George Drive, opened 1994) and VSS-West in O'Fallon (7770 Winghaven Boulevard, opened December 2017). Founded by Dr. Mary Jean Gorse, DVM, MS, DACVS, and joined by partner Dr. Mark Anderson in 1996, VSS serves pets referred by primary care veterinarians across the St. Louis metropolitan region and surrounding states. The practice runs board-certified specialty services across seven disciplines: cardiology, critical care, internal medicine, neurology, oncology, radiology, and surgery, with advanced interventional capabilities including pacemaker implantation, PDA correction, balloon valvuloplasty, and pulmonic valve stenting, plus orthopedic procedures such as TPLO and total hip replacement. Walk-in 24-hour emergency care is available at both locations without referral.

The underlying technology stack centers on advanced diagnostic imaging — a 1.5 Tesla MRI, a 16-slice CT scanner, digital fluoroscopy, two DR-system radiology suites, and ultrasound — interpreted by board-certified radiologists. Clinical operations are supported by a proprietary Veterinary Portal that gives referring DVMs online access to patient records, and by a co-located rehabilitation partner (Healing Paws Rehab) offering hydrotherapy, electrical stimulation, therapeutic ultrasound, and land treadmill services on-site at Manchester.

VSS generates revenue on a fee-for-service, transaction-based model: payment is due at the time of service for both emergency visits and specialty consultations, with deposits collected upon hospital admission based on estimated care costs. Accepted payment methods include cash, major credit cards, CareCredit, and Cherry buy-now-pay-later financing; no subscription or capitated pricing is offered. The go-to-market motion is referral-led — primary care veterinarians submit referrals through an online specialty service referral form, and department coordinators schedule appointments directly with pet owners. Marketing channels include a referral network, Facebook and Instagram presence, the vssstl.com website, and an annual DVM Continuing Education conference. VSS is the self-described largest privately-owned multi-specialty and 24-hour emergency hospital in Missouri, with no parent company, no venture funding, and no disclosed acquisition history.
