I have been a patient of Dr. Lonner's since 1999 when he took over the practice from Dr. Stanley Hoppenfeld, who was my original scoliosis doctor. Dr. Lonner performed my second spinal fusion surgery when I was 16, and a few years later operated on my father twice. To us, he is like family and he treats us like family. He is incredible and saved my life. If your child was recently diagnosed with scoliosis, or you have scoliosis or another complex spinal disorder, go see him. He is the best! World-class care.

"Straight" to the point....His patience and knowledge are second to none AND he's likable too! :). He was not the first doctor I went to after my daughters scoliosis diagnosis but he was the last, After our initial meeting I felt a sense of calm and I knew he would be the surgeon that I would trust with my daughters surgeries.. Looking back at her before and after xrays, I am simply blown away and forever grateful. I must also commend his entire staff both past and present. Thank you!!

Our family has been so blessed to have met Dr. Lonner and his wonderful staff. Dr. Lonner performed surgery on our 12 year old (baseball player) on August 1, 2017 and 3 months later he was fully released to play baseball again thanks to Dr. Lonner. I would recomend Dr. Lonner to anyone that is considerings spinal surgery for their child, he truly is the best. He cares very deeply about the parents concerns and wishes for their children health.

I would never recommend this doctor. I took my daughter to Dr. Lonner for scoliosis. He made me feel an urgency to rush into surgery when there was no need for that. Not only did he perform spinal fusion with instrumentation, but he did this surgery incorrectly so my daughter had to get a second surgery a year later. That was the worst experience of my daughter’s life. Dr. Lonner botched that surgery, incorrectly put in the screws, and has left my daughter with daily pain. NEVER see him.

I was in severe pain almost at the point of not being able to walk and facing a major surgery. A Laminectomy and decompression of multiple discs from the thoracic section of my spine to the lumbar section including rods and screws. Dr. Lonner was thorough in explaining every aspect of the surgery. He is the epitome of professionalism. I wouldn't have done it if I didn't feel as comfortable as he made me feel. Because of him I have my life back. He took care of like no other surgeon could

Dr. Lonner is very professional. I put my trust in him 100%. Having 3 spine surgeries I have been treated with the utmost of care and respect. My family feels very comfortable also in Dr. Lonner's decisions about my treatments. I highly recommend Dr. Lonner to any one searching for a scoliosis Dr.

Dr Lonner performed my surgery in October 2016. I had some concerns and I was given an appointment really quickly. Dr Lonner spent time talking through my images and reassuring me. He really is one of the kindest, most supportive surgeons I have encountered (that's in 35 years of having spinal surgery!). His surgical skills are second to none but his bedside manner and the care he shows his patients is truly heart warming. I cannot recommend him highly enough!

Should have been the scariest time in the lives of my daughter and my family. Instead it was a kind, caring, loving, reassuring and blessed experience. Six weeks out and ready for school.. Thanks Dr Lonner, Michele and rest of the outfit/team.

My daugher had a pretty severe case of scoliosis and wore a Boston Brace for 2 years only having to find out that it would have never corrected her curve or even truly make much of a difference. After her orthopedic dr. retired, I then reached out to Dr. Lonner who performed my daughter's surgery. He is brilliant, kind and is great with the kids and parents. My daughter loves him and he was there by her bedside right after surgery. I highly recommend Dr. Lonner.
