PhysicianOne Urgent Care Groton

The Premier Urgent Care Center Serving Groton, CT & Surrounding Communities

If you’re in need of walk-in urgent care in the Groton, Connecticut, area, turn to PhysicianOne Urgent Care. We were founded by a team of physicians in 2008, and we’ve been serving local patients at our Groton office since 2014. We were Connecticut’s first urgent care center to be certified by the Urgent Care Association (UCA), and we’re proud to be an affiliate of the esteemed Yale New Haven Health System.

Our Walk-In Urgent Care Services

At PhysicianOne Urgent Care, we pride ourselves on offering a wide range of urgent care services, including:

  • Treatment for non-life threatening illnesses and injuries
  • X-ray imaging
  • Lab work
  • Occupational medicine
  • Physicals for school, sports, camp, and work
  • Vaccinations

We’re open 365 days per year with extended hours, and we never require appointments. Instead of waiting to schedule an appointment for these services with your primary care provider, you can stop into our Groton location at a time that is convenient for you. To minimize wait times, we offer a convenient online check-in system. You’ll also be glad to know that we accept most major health insurance plans and offer affordable self-pay rates.

Stop By Our Local Urgent Care Center

Our Groton office — conveniently located at 220 Route 12, near I-95 — is a great choice for residents and visitors in Mystic, New London, Pequot, Waterford, and other nearby communities. We’re just a short drive from attractions such as Connecticut College, the Mystic Aquarium, the Mystic Seaport Museum, the Naval Submarine Base New London, and the U.S. Coast Guard Academy. And, we’re very close to a number of local hotels — including Best Western Olympic Inn, Groton Inn and Suites, Hilton Garden Inn Mystic/Groton, and Super 8 Groton — making us an excellent option for travelers in need of urgent care treatment. Look for us in the Groton Square Shopping Center.
