    Probably the best chiropractor i have had ever. If I go regularly my neck would be completely healed.

    I have a torn rotator cuff and probably frozen shoulder. The surgery recommended is absurd -…read moreoutpatient but eight months of oppressive recovery. Pass. PT was my only hope. When I started at Nova, I couldn't even put a shirt on without crying and swearing, and sleep was poor. My headspace was bad. So I needed both effective physical care and supportive emotional care. I got both at Nova. Dr. Kev, Izzy, and Autumn were my main care team. I adore these people. Kev constantly assessed and amended my routine to aid recovery, and encouraged me to keep working at home. But when I got wonky, he also provided gentle but authoritative nudges to get me back on track. Additionally, he's a real good guy and a hoot to talk with. Izzy and Autumn keep the busy practice running smoothly, pay good attention to everyone, and are absolutely delightful people. While the other team members weren't as involved with my care specifically, it was obvious every time I was there that it's a wise, collaborative, happy crew. Today was my last session. I can cough without crying, get dressed without screaming, put on a seat belt normally, and am getting back into working out. The extent to which Nova helped me can't be exaggerated; it is substantial. And I am extremely grateful. Less important but good to know: parking is good in the lot and on the street, and there's a Randy's Donuts right there (blueberry glazed is a good post-sesh reward). If you're in pain, you'll be in great hands at Nova Physical Therapy.

    The team at Nova are a professional, and welcoming. I have a frozen shoulder with a couple of tears…read moreand they worked with me these past few months to regain my strength and mobility of my arm. Thank you Nova! I definitely recommend them.

    I came to Performance care specialist for their physical therapy because I had two displaced ribs…read morewhich was painful and I was in constant discomfort. After working with Kevin Zhang, doctor of physical therapy and Jojo Cruz, it has literally changed my life. Kevin and Jojo immediately started to build muscle around my rib cage to keep my ribs in place. What I love most is the personal care and attention I receive. I totally trust their expertise. They are dedicated to helping me improve my motor skills and they are truly professionals. I must say too, the professionalism doesn't stop at Kevin and JoJo as the front desk has always been so accommodating making sure there's always room for me to get therapy 2 times per week. Performance Care is the icon for 10 star service you can trust and rely on.

    You won't find better. The doctor there is concerned only about your well-being not about how much…read moremoney to make off of you. He recommended I get an MRI and directed me to the correct treatment. He could've told me I needed 20 treatments at his place and I would've done it 100% but instead he directed me to the correct thing to get my problem solved and charged me nothing. The doctor (Golan Nissim) is a real nice guy who cares about you and this is reflected through all his staff. They provide numerous types of treatment and whatever your needs are. I highly recommend Performance Care.

    This review is not for the doctor it's more for staff and how the office is run. After waiting over…read more1 hour to speak to someone regarding my authorization I get transferred to a voice recording stating they will be closed for Juneteenth. It's April 1st . Clearly that was an old recording. It's very frustrating to be on hold for over one hour a d not be able to get a hold of anyone. Very disappointing and unacceptable. Thank god I snapped a pic to send to my sister how ridiculous it was I was on hold for so long. If I didn't have a screenshot they would've probably denied it.

    The Doctor is brilliant! After two knee replacements and months of superb physical therapy via OSS…read moreI had nothing but positive things to say until.... This last Monday I saw the doctor as my left knee is hurting, the doctor prescribes an ointment to apply a couple times a day and I am to follow up in 30!days. My issue here and reason for a negative review is with the doctors staff, some of them cannot or are not able to do their job. Since Monday afternoon I've been waiting for my prescription.... I called Wednesday, two days after my appointment and after 38 minutes on the phone I was told it'll be sent to my pharmacy by end of day. Today is Thursday and four days since I saw the doctor and I still don't have my prescription. No one there at oss can seem to send over my prescription to Walgreens. How hard is this task I ask? Apparently some of the doctors new staff are incapable of performing simple duties such as sending over a prescription in a timely manner. No other doctors office takes this long.... Normally any prescription is sent electronically by the end of that day or even within hours of you leaving their office. Why are the doctors staff at oss unable to complete a simple task? We have called the office now twice since my Monday appointment. It should not require even a call to ask him um did you send in my prescription? Each phone call it was a game of not my fault and we are busy and have lots of patients.... None of these excuses hold any weight! It's your job to follow through and make sure simple tasks as this are completed. Clearly some of the newer staff are in over their heads. The staff used to be so efficient, polite and professional, yet now today that has sadly changed. Again, the doctor is one of the best in his field yet some of his newer staff simply are not up for the jobs they now hold and should be replaced by those who are more on top of their game. I am so dissatisfied and disappointed by how such a simple task as sending in a prescription that was written Monday has yet to be sent electronically to my pharmacy. It's almost comical but I am not laughing. Lastly, there are no excuses for incompetence nor for ignorance and unwillingness to just do your job, I'm sure these newer employees could use a Starbucks or Alfred's coffee card to wake up and perform their daily tasks with more proficiency and pride which is lacking at the moment. If that does not solve the issue then maybe let them go and hire those who can and will do the job faithfully. Lastly, and a second complaint if you will. Two months ago I needed to reschedule a procedure. I called and left two messages with dr. Jeters (another incredible doctor there at OSS, like Dr Yacoubian, on top of their game and profession!) scheduler and have yet to get a return call to reschedule. After two months waiting I went elsewhere It must be so busy there that one must call more frequently or simply walk in and ask to speak with the scheduler or whoever in person. Far more labor intensive than it should be in all sincerity. Appreciate and admire the doctors there, love most the staff and all the physical therapists upstairs are dedicated and caring, yet these newer staff members really need a good taking to and just do your job please with no excuses or anything but just do your job do your job!:)
