Marlboro Internal Medicine

Our practice was founded in 1998 when Dr. Lalita Matta decided to become independent to better meet our patients’ needs. In 2010, our practice became complete with the addition of Nurse Practitioner Estrela Chaves, who brought with her over 20 years of experience. Our independent status means we are not managed by a hospital or other healthcare organizations.
