Urgent Care & Primary Care Services in Hunterdon & Warren County NJ Since 1987 we have been rendering high quality cost-effective medical care to our community. Long before the urgent care center explosion, The Doctor Is In offered a broad scope of services, extended hours, on-site lab and X-ray, and no appointment necessary. What distinguishes us from other walk-in centers is that we are not just urgent care. We can be your Primary Care Provider (PCP). Our Board Certified Physicians and Certified Physician Assistants provide primary care to patients of all ages, participate in many insurance plans, schedule appointments at our patients' convenience and manage chronic conditions as a Patient Centered Medical Home.
