Since 1956, the practice has provided comprehensive family healthcare, including routine exams, vaccinations, wellness visits, physicals, screenings, and treatment for everyday medical needs.

Services span cardiology, gastroenterology, nephrology, physical medicine, podiatry, general surgery, behavioral health, and more, with extended hours and telemedicine options available seven days a week.

Founded in 1956 by Dr. Joel Mayer in Avenel, the practice began as a solo general medicine practice before merging with Dr. Robert Maurer’s Iselin-based practice in 1975 to form Avenel-Iselin Medical Group. The Mayer family continued the tradition, with Dr. Marc Mayer joining in 1985 and his brother Dr. Mitch following in the years that followed. Over decades, the group has remained rooted in the community, evolving into a multi-specialty provider while maintaining a personal, patient-centered approach. The practice emphasizes continuity of care, offering services such as Medicare visits, mobility assessments, and on-call support, and has long been recognized for its accessibility and comprehensive care model.

Nearby landmarks include the Goddard School in Woodbridge, less than a quarter mile north, and the South Branch Rahway River to the west.

With a strong foundation built over more than six decades and supported by a large base of customer reviews, Avenel-Iselin Medical Group is known for its longstanding commitment to accessible, family-oriented care.
