About
Station Plaza Veterinary Group
More Than a Neighborhood Clinic—A Complete Care Partner
Founded in 2007 by Drs. Kristen Sullivan and Cathy Roncskevitz, Station Plaza Veterinary Group has become a trusted favorite for pet families across Nassau County and Long Island’s North Shore. Known for our personalized service, experienced team, and compassionate care, we’ve even been recognized as Best of Long Island by the Long Island Press.
In 2025, we proudly joined the West Hills Family of Veterinary Practices—a network of leading hospitals and specialists dedicated to advancing the health and happiness of pets across the region.
When you visit our practice, you’ll most often see Dr. Sullivan, Dr. Lotus Altholtz, or Dr. Roncskevitz. They are our primary doctors and work closely together, staying familiar with all of the cases in our hospital to provide a personalized experience for you and your pet. At times, you may also meet one of our trusted veterinarians from the West Hills network who help provide additional coverage and continuity of care.
The West Hills Family of Practices
Comprehensive Care for Every Stage of Life
As part of the West Hills Family, Station Plaza now offers more than just exceptional primary care—we’re your pet’s full-service care team. Whether it’s a routine checkup or an unexpected emergency, we have direct access to a network of six sister practices that provide:
- Advanced diagnostics
- Specialty services (including cardiology, oncology, surgery, and more)
- 24/7 emergency and critical care
Through this collaboration, your pet’s medical records travel securely with them across all locations, so there’s no need to retell your story or duplicate tests. That means faster answers, smoother transitions, and complete continuity of care—whenever and wherever your pet needs it.
With Station Plaza and the West Hills network by your side, your pet is never far from expert, compassionate care.
Personalized Service, Big Picture Support
At Station Plaza, we remain the same friendly, familiar team you know and trust—but now with more ways to support your pet’s health, comfort, and longevity. Whether you’re visiting for vaccines or need a trusted referral, you’re backed by the strength of a connected, compassionate network.
