Whole-Person Care for Every Stage of Life

Board-affiliated family medicine in Hewitt, NJ, open seven days a week for children through seniors.

About Us

At Suite 303 on Union Valley Road, Dr. George Guariglia has built a family medicine practice around a simple conviction: a doctor should treat the person sitting in front of him, not just the chart on the screen. Patients who have followed him for years describe the same experience, that he slows down, listens carefully, and addresses worries head-on before they leave the room. That kind of attention is increasingly rare, and it shows in a 4.2-star rating earned across nearly 200 reviews.

Dr. Guariglia is a Doctor of Osteopathic Medicine affiliated with Hackensack Meridian Medical Group, which means his training goes beyond conventional primary care to include a whole-body framework for understanding how structure, function, and lifestyle connect. He cares for patients at every life stage, from pediatric visits to geriatric check-ins, all under one roof in western Passaic County.

The practice runs Monday through Friday from 7 AM to 7 PM, with Saturday and Sunday hours as well, so working families and weekend-only patients can find a time that actually fits their lives.

What We Offer

Family Medicine is the foundation here, covering preventive care, chronic disease management, and acute illness visits for children, teens, adults, and seniors. Because Dr. Guariglia holds a D.O. credential, he also offers Osteopathic Manipulative Treatment (OMT), a hands-on technique that addresses musculoskeletal restrictions and supports the body's natural ability to heal. Few primary care offices in the area combine both under one provider.

For patients who cannot make it to the office, Virtual Visits are available, letting you connect with Dr. Guariglia's team from home for appropriate concerns. Booking is handled through the Hackensack Meridian Health patient portal, giving you access to a broader network of specialists and records if a referral ever becomes necessary.

Whether you are establishing care for a new child, managing a long-term condition, or simply overdue for an annual physical, the extended daily hours mean you are not choosing between your health and your schedule.

"The personal connection, even in its bases form, is being lost in this office. Reaching the office is impossible as a call center now answers calls and promises call backs at a later date. The physicians/practitioners/nursing staff don't reach out to people, they let you find out results through Mychart or by getting calls from Labcorp, Radiologist, or specialists requesting you make an appointment. Surprise, somethings wrong but your doctor never told you, some stranger did. I'm sure it's not just this office but its disappointing after being a patient and bringing my family there for well over 10 years that there is a serious lack of compassion and understanding of how to treat people that trust you to have their best interests at heart. I called to make fhis same claim to someone and was told well, we sent you the details online. Tone deaf response. Do better."

"Dr Guariglia has, over a number of years, been a trusted health professional to both me and my deceased husband. He got us through Covid when others were unable to do so.. He is caring and thorough in his assessments, and appreciates his patients’ needs and daily life occurrences. I highly recommend him as a PCP to anyone seeking an experienced, caring healthcare professional."
