    Northfield's staff also was patient as we dealt with two insurance companies playing real games trying to not pay.

    I had multi level lumbar fusion surgery with Dr. Su in December. I was in horrific pain and he…read moremoved a surgery to be able to get me in! The staff has been consistent and responsive - well beyond most Dr. Offices. Previously, I had cervical fusion/decompression surgery and lumbar decompression at UCSF. Every day I wish with all my heart that I'd gone with Dr. Su for those. It's hard not to blame myself because I'm convinced if I'd gone with Dr Su initially I wouldn't be left with cervical chronic pain. Dr Su's approach is to do the most minimal surgery because you can always do more, but can't correct surgery that shouldn't have happened. In my case, this lumbar fusion and reconstruction Dr Su did on November was to correct the first aggressive lumbar decompression at UCSF. I'm now 6 weeks post surgery and feel like I'm getting my life back! Nerve recovery has been difficult and painful, and the staff has been incredible at addressing it. For the first time I feel like I'm part of a team working to heal me. Shout out to PA's Connor and Julie, and Anna and Bruno for back office support. One more thing to consider...the practice consists of several high quality doctors that offer supporting procedures adjacent to surgery.

    Review for Dr. Naidu and Dr. Su…read more Apologies for the delay in writing this review--but my gratitude has only grown with time. Thank you, Dr. Naidu, for truly changing my life. One of the things I appreciated most was how honest and transparent both you and Dr. Su were with my prognosis. Your directness allowed me to make informed decisions without false hope, while still feeling heard and respected. You didn't just prescribe a path--you listened to my concerns and worked with my choices. The main reason I chose to fly from Los Angeles--despite the costly flights and hotel stays--was because you believe in starting with conservative care before jumping to surgery. That meant everything to me. Although Dr. Su thought my lower back MRI showed serious issues, he still agreed to try epidural injections first. Thankfully, I only needed two. Those injections gave me my life back. Before meeting you both, I had been off work for six months. Every provider I saw in L.A. pushed for surgery. As a nurse, I've seen patients come back years later with even more pain after surgery. I know surgical techniques have evolved, but I wasn't ready to take that step without a team I could trust--and I trust you both. Just three weeks after my first injection, I returned to work. I'm on my feet 12 hours a day, and I was finally able to do it again. Thank you--truly. My husband got his wife back. My kids got their mother back. Before treatment, I looked and felt ten years older. Now, I feel like myself again. I had been managing well with just Tylenol and ibuprofen for the occasional mild pain. But I made the mistake of seeing a chiropractor recently, and everything changed. My MD ordered a new MRI, and now both my neck and lower back are flaring up again. So--my next visit with you is already booked for August, flights and hotel included. I'm hopeful once again. Lastly, Dr. Naidu--thank you for fitting me in on my first consultation. When I look back, we laugh now about how I begged you to give me that first injection right away. You told me to be there at 8 a.m. because you had a small gap in your schedule--but what you didn't know is that I was already parked outside your building by 7 a.m. I wasn't going to miss that appointment. Best decision I ever made. THANK YOU, THANK YOU!!! Dr. Su--I'll never forget when you looked at my MRI and said, "Oh no... your back is messed up. The epidural won't give much benefit." You had such a straight face that I thought to myself, Oh no... if he can't help me, I'm in deep sh--. But despite that, you still advocated for me. You spoke to Dr. Naidu, and he gave me a life-changing injection. THANK YOU. Just two injections--and I've been doing well ever since! Please, don't give me that look again when you see my MRI this time. Words alone can't express how grateful I am. Thank you.

    Dr. Harf has been my orthopedist for over 25 years. When I…read morefirst met him I couldn't walk, I was in intractable pain for a herniated disk which had been going on for about 8 years. Especially back then everybody said "oh no, don't get back surgery, you get the surgery, you're done.My uncle . . . my friend . . . scary" Finally it was pressing on the sciatic nerve so badly I couldn't walk. I thought my life was over. Since I was "done" anyway, I had the surgery. That was in 1989 I think. After recuperating and getting my muscles in shape I've been completely pain free. I was able to coach my kids baseball and soccer teams, be a soccer referee, running up and down the soccer field with a bunch of 16 year old "cheaters" was unthinkable before I met Dr. Harf. The guy knows his craft. Don't worry about the people here that don't get him. After getting to know him as his patient all these years, and having broken my body several times and having him fix me up every time, I love the guy. He's is a very decent human being and a fine Doctor, he's from New York and I know some Californians don't get New Yorkers, so that . . .. As another poster observed, you want "warm and fuzzy" get a dog, you need a good orthopedic Doctor? Don't be a pain in the a**, let Dr. Harf help you.

    Unprofessional, Dismissive, Poor Manners…read more He did surgery on my father's knee. When he went through PT, he complained of pain and his leg was still excessively swollen. Dr Harf's reply was, "I don't have anything to do with that, you have to talk to your doctor". Now, here we are 7 months later and my dad has to go in for another surgery because Dr Harf neglected to repair all of the knee correctly. He is dismissive, judgmental, rude, and not thorough. He should be seriously assessed for his medical license. Save yourself trouble and get a referral to someone else.
