HumanizeMD Profile

I was born in Brooklyn, but came to Monmouth County with my family in 1957 when still a toddler. I’ve lived all my life here. All the time I was growing up, my father was an orthopedic surgeon in Monmouth County, and two of my uncles were also doctors. That’s how I came by my interest in medicine. Sometimes I would go to hospitals with my father, and so I was exposed to the surgical aspects of it, and other procedures like putting casts on people. I enjoyed watching, and learning. I also noticed how well my father would relate to people, and I came to realize that his patients were just as devoted to him. Not only did he help people with their illness, he made a connection with them on a personal level. I decided early on that I wanted to be a doctor – the same kind of doctor as my father. I wanted to practice medicine with all the scientific expertise and training that’s essential to do the job well, but also to put patients at ease, answer all their questions in plain language and allow them to participate in their own healthcare decisions.

I completed my Orthopedic training at UMDNJ/Newark, where I served as administrative chief resident at the Level One trauma center. This is one of the busiest trauma centers in the U.S., and there I was exposed to lots of traumatic injury and reconstructive procedures. In a way, it was a trial by fire, but it gave me really good surgical training. There’s not much that will face you in private practice that you haven’t seen in a program like that. It prepared me to deal with all kinds of chronic and acute pain due to hip, knee and shoulder injuries.

I opened my practice in 1988, so I’ve been practicing in Monmouth County for 29 years. I’ve always felt it was a beautiful, safe place to raise a family – a nice mix of suburban and rural, and not far from New York City and Philadelphia. Also, there’s the ocean, which gives me the opportunity to relax with my favorite hobby – fishing.

I come from a family of 8 children, and my wife and I have raised 5 of our own. One of my sons is graduating from medical school this spring, and he will begin training as an orthopedic surgeon in the University of Miami in June. He is looking forward to joining my practice when his training is complete – making the third generation of orthopedic surgeons in the family!

I love what I do, and I wouldn’t change a thing. I am a sole practitioner because I want to answer only to myself and my patients, not some group practice or bureaucratic organization. This allows me to set my own schedules and devote the time and attention that each patient deserves, to answer all their questions and for us to get to know each other. I don’t mind the extra work that this entails. Moreover, when I go to the doctor I hate having to sit in the waiting room for a long time. I value my patients’ time, and I don’t want them waiting for an hour in the office to see me.

When a patient comes in they know they will see me, not some other doctor, from diagnosis through recovery. I want to establish and maintain that unique personal doctor-patient relationship that I admired so much when watching my father. That’s why the motto of my practice is, ‘One Doctor, Your Doctor.’ I wouldn’t have it any other way.

Hear From Our Patients

I have been a tennis player my entire life and unfortunately it has taken a toll on my knees. I was going to another doctor who I felt was not giving me the proper care. One day I walked out of this other doctors office in pain and called a friend who told me about Dr. Allegra. Both my friend and her husband are patients of Dr. Allegra. I called the office and bc I was in pain they brought me in immediately. The office staff couldn't be nicer. I met Dr. Allegra and found him to be compassionate and caring. He listened to my concerns and gave me options. Two years ago he did meniscus surgery on one of my knee. His surgery after care and pain management is amazing. He really cares about his patients.

Dr. Allegra is the BEST! I separated my shoulder and was experiencing a lot of pain in my day to day life. After seeing Dr. Allegra, I could not be happier. He performed an arthroscopic procedure in less than an hour and repaired the damage to my shoulder. In less than a week I have full range of motion and already feel better. The most painful part of this entire experience was having an IV put in! He has an excellent demeanor and is great at what he does.

Dr. Allegra is my go to guy for anything that hurts. His office is a pleasure to visit with a professional, courteous staff and appointments are handled promptly. I am always seen within a reasonable time, if not immediately after showing up. His bed side manner is aggressive with no BS and he always knows exactly what is needed to be done. Treatment is scheduled quickly if not during the office visit when able to. My surgeries were treated promptly and recovery time was at a minimal. A++++++++


About Us

Dr. Marshall Allegra has been in continuous private practice in Monmouth County since 1988. He has a private practice in Hazlet and has affiliations with Riverview Medical Center, Bayshore Community Hospital, Shrewsbury Surgical Center, and Metropolitan Surgical Institute. Dr. Allegra is one of the few doctors who perform Hip Arthroscopy, a less invasive procedure than hip replacement. His practice specializes in performing them as a same day outpatient procedure, and as a result patients experience a faster recovery than with traditional open surgery. Dr. Allegra also performs partial and complete hip and knee replacement surgery, utilizing a minimal incision approach, in addition to knee and shoulder arthroscopy.
