History of Our Practice

Since opening our first office in 1987, the commitment of The Doctor Is In has remained the same:  providing the most convenient and cost effective quality medical care possible.

Founded by Randy Klein, MD, Medical Director and practicing physician at The Doctor Is In, the Clinton office has been serving the community for over 25 years.  Staffed by Board Certified Physicians and Certified Physicians Assistants, the Clinton office is open 8 AM to 10 PM 365 days a year. 

As the population of Hunterdon and Warren Counties has grown,  so too has The Doctor Is In.  To meet the needs of families and employers in the surrounding communities The Doctor Is In expanded by opening the Flemington office in 1996 and the Phillipsburg office in 2001. 

What distinguishes us from other walk in centers is that we are not just urgent care.  We 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.   We take pride in the fact that we are currently caring for the grandchildren of some of our first patients.
