I was there for knee pain and all he did was read over my previous doctor's notes (now retired) and we agreed upon my continuation of the Euflexxa injections for my knee. I was shocked that he never even examined my knee durning my first office visit with him. This appointment was over six weeks ago and I am still waiting on an approval for my Euflexxa injection which usually takes 1 to 1 1/2 weeks for the approval. I have spoken with Cecily at the office for help on two occasions. The first occasion, she said the there is a delay with Optum and could take up to 4 weeks for approval. Please keep in mind that I am in knee pain. When I called again on August 10, 2026, Cecily said that she cannot tell me the status of my medication and would leave a message for the person who could help me. This person who Cecily promised would help me, never called me back. Wednesday of last week, I called my insurance provider in order to help me find out the status of my medicine and we spoke with Karen. Karen promised that we would have the medication by last Friday. Once again, Karen nor any other person called me back from Dr. Nadel's office. As of yesterday, I filed a complaint with my insurance provider and the lack of help with Dr. Nadel and the office staff. How can the office staff here ignore someone who's in pain and not work on getting the medication that I have been using to relieve the pain now for a couple of years. This is unconscionable.

I cannot say enough wonderful about Dr. Raven. I came to him after three years of dealing with a…read morepainful trigger finger. He shared with me that he could get this better with an in-office procedure (amazing!). His caring assistants, Alexa and Kristine, supported me as I scheduled my appointment. Throughout the entire process, Dr. Raven was extremely kind and caring. I was able to go home afterward, and use my hand for many tasks immediately. Dr. Raven was very supportive in answering my post-procedure e-mail questions, and I am now looking forward to living a hugely improved quality of life, due to the amazing skill of this very special physician. It is a privilege to be a patient of Dr. Raven!

The support staff was fine, but Dr Raven has a very condescending attitude.

He was excellent and explained what to do and not do. Dr. Lian is who I met with about my frozen shoulder/calcification on my left shoulder. After PT did not help we decided to do surgery.

Some folks on here talked about the wait time which I expect at most doctor's offices. They are busy and if they accept insurance, I expect them to be busy. They always apologize if/when it happens but mostly it has been short wait times.

This doctor did a lumbar fusion on me back in 2009 and I have spent the last 16 years dealing with the pain and fall out from his incompetence. The mistakes that he made required multiple corrective surgeries and has seriously impacted my quality of life. Every spine doctor I have seen after Sperling has stated that he botched the procedure. There was a slippage that was not corrected in the nine hour surgery. Therefore, I've suffered severe nerve compression and pain as a result. He was clearly not skilled or experienced enough to do this type of surgery and I paid a heavy price. When he couldn't handle the post op issues anymore, he referred me to another doctor to correct his mistakes. Very unprofessional doctor and office. I cannot emphasize enough how sorry I am that I used this person. I didn't get multiple opinions and ended with disabling symptoms that will last a lifetime. To make matters worse, the staff was incredibly incompetent and rude. Don't make the mistake I made - do yourself a favor and go to someone else. I paid too big of a price trusting this person who didn't know what he was doing.

He and his staff have been at the top of my "favorite doctors to recommend" list ever since! They consistently provided my friends and family with premium care and the best outcomes. In fact, he's treating me now and although he explained my diagnosis to me thoroughly and could fix the issue with surgery, instead he advised me to consult two other doctors before even considering surgery with him. I'm sharing this because it helps show who he is. A brilliant, thorough, patient-oriented doctor who takes the time to lay out every angle and offer his expertise, while acknowledging when other doctors should be consulted to create a complete picture. Btw, I also trusted him with my daughter's injury and she has made a full recovery to earn MVP on her varsity tennis team! I know few people "Yelp" when all goes so well, but I am "Yelping" to let you know that Dr. Ouzounian is the GO TO doctor for those who choose the best care for themselves and their family.

When I called to schedule an appointment, I was connected with a staff member named Craig at the front desk. His behavior was shockingly unprofessional -- he was rude, dismissive, and clearly rushed to get me off the phone. He asked inappropriate and confusing questions, showed zero patience, and made me feel like an inconvenience rather than a patient. If this is how new patients are treated before they even walk through the door, I have serious concerns about the overall quality of care at this office. Craig seems to genuinely dislike working with people, which raises the question -- why is he answering phones at a medical practice? Front desk staff are the first point of contact and represent the entire practice. Craig's behavior is damaging to Dr. Brookinghalt's reputation. I strongly recommend the management review how patients are being treated by this individual.
