I had a severe sinus infection, which I get on occasion. I have been suffering from sinus issues since I was a child. When I called his office I was informed he had no appointment for several weeks, but they would put me on a waiting list. I was never called back. I recently received a reminder notice for my "annual checkup" made the appointment. When I mentioned this to Dr. Cohen he was quite dismissive and explained to me that he is only doing procedures and I should be calling my internist for these type of issues. I was quite taken back since he is an ENT and that is what ENT's typically deal with sinus issues. The next day I called the office manager to make sure that what he told me was correct and I did not misunderstand him. She then explained the same exact thing he told me. In other words I need to find another ENT that practices what a ENT does, help patients with chronic sinus issues. I was very fortunate to find another office that has been wonderful and caring. Their office is incredible and they also have the ability to do full sinus exrays and spent a great deal of time with me showing me why I have these issues and have scheduled me for a balloon procedure which was very obvious from the x rays. Dr. Cohen is a great Doctor, but his new office practice is quite unusual.

I don't usually leave reviews, but I feel strongly that people should be aware of this experience…read morebefore coming here. I went in with a locked jaw and significant pain on the lower left side, expecting to receive care that would at least begin to relieve my symptoms. I was seen by Dr. Farshid Ariz. I had previously come across negative reviews about him at another location, but when I booked at the Northridge office, I was not aware he would be the one conducting my exam. To be fair, the doctor appeared knowledgeable and performed a thorough consultation. However, that is where the patient care essentially stopped. The moment the treatment coordinator stepped in, the entire focus shifted away from treating my pain and toward selling a HIGH-COST treatment plan. After nearly two hours, instead of initiating any form of relief as discussed, I was presented with a treatment plan exceeding $5,500. When I clearly stated that I could not afford that and asked to begin with the oral appliance the doctor himself recommended, I was told they would not proceed unless I committed to the full plan. The price was slightly reduced by couple hundred dollars as a "gesture," EVEN after I mentioned I did not expect anything over $1000 to relieve some pain but the expectation remained the same--pay thousands upfront or receive nothing. For context, I have over 15 years of experience in the dental field, working in both general and specialty practices. I am fully aware that the lab cost for a night guard-type appliance is minimal, and that fees should reflect clinical care--not be used as leverage to force patients into bundled, long-term programs! I was also told that part of the treatment would involve seeing a "specialist" via Zoom from their office regarding a possible deviated septum--but only if I agreed to the entire plan. No detailed breakdown of the treatment was provided, despite the significant cost and me asking multiple times to get a breakdown. In reality, addressing a deviated septum through a licensed ENT specialist would likely be more direct and cost-effective than committing to a year-long program of weekly visits and vague "therapy" that may or may not help! A dentist's responsibility is to help relieve a patient's pain--not simply give an opinion and then hand the case off to a coordinator whose primary role is financial. The treatment coordinator showed no empathy for my condition and made it very clear that the priority was securing the full fee, not helping me manage my pain or offering reasonable, step-by-step care. Despite multiple requests to begin with the appliance to get some level of relief, they refused unless I agreed to the entire treatment plan. That directly contradicts what was initially promised and, in my opinion, is both unethical and misleading. Based on my experience, this office operates in a way that feels predatory. The priority is not patient care--it is enrolling patients into expensive, all-inclusive programs with no flexibility. I left feeling that this is not a practice focused on treatment, but one focused on maximizing revenue. I will include the picture below of the appliance the doctor recommended--a simple plastic mouth guard to wear for 10 weeks. They refused to let me start with just this, and the coordinator claimed most of the $5,000+ cost was tied to this appliance.. ha ha... Honestly felt like they expected me to believe this small piece of plastic justifies that price. I can tell it for 100% this costs less than $250 from the lab! I cannot recommend this office, as stated in other reviews, RUN don't WALK!

Slowly, over time, the pressure from the device moved my bottom teeth forward so much that I ended up with an underbite that I didn't have before. It completely deformed my teeth. I now have to use invisaline braces to try to restore my bite, but my teeth will never look the same. The mouth appliance was 4,000 dollars and the invisaline is 8,000 dollars. So I've paid around 12,000 dollars just to have my teeth deformed and to try to get them back to normal. If you have sleep apnea, use a cpap machine instead and get it from someone else! These people only care about selling as many of the mouth appliances as possible.
