I have been a patient of Dr. Ha for years. He performed my nose surgery and I also see him twice a year at his clinic; I have always had an excellent experience!! He always takes the time to listen to my concerns, answers my questions and doesn't make me feel rushed. I appreciate his consults, his level of care and highly recommend him for both surgery procedures and office visits. I believe Dr. Ha is a top-notch physician and surgeon. The staff is always welcoming and friendly. read more

I've seen a lot of doctors (not bragging), and Dr. Ha is easily the best ENT physician/surgeon I had the pleasure of interacting with. He is extremely intelligent, confident, highly skilled, and caring. His office staff members have been nothing but professional as well. I would recommend making an appointment with him as soon as possible if you're serious about getting quality treatment; because we all know how fast California is filling up with people, so the wait might be extended, but definitely worth it. read more

Dr. Ha is an ENT. If you can get in to see him, he is the ENT you want. I have been to dozens of doctors from previous industrial and automotive injuries. So I have a fair amount of experience with doctors. Dr. Ha is in the top 3 doctors I have seen. Okay, I'm a little biased because my daughter is included in my top 3 as well. Dr. Ha listens and considers what you have to say. He is thorough and thoughtful. He really did make a difference in my health. The office staff is fantastic as well. They are very kind and patient. read more

Castellanos Family Practice

Available by appointment

I used to see Dr. Castellanos when I was a kid with my mom, roughly between the ages of…read more12-15(2004-2007). Now as an adult I've realized how horrendous of a doctor he was. Our family eventually stopped seeing him after 3 years of being under his care. We went to him because it was hard to find doctors who spoke Spanish in our area at the time. I'll start with the worst. My mom used to be really concerned for her health. Over time we realized her concerns were signs of what she's now developed, diverticulitis and other digestive issues. She often came in with pain and explained her concerns. Dr. Castellanos would tell my mom that she was fine and to take ibuprofen. Any time she came in it was the same thing even though her symptoms progressed - continue to take ibuprofen. Eventually she told my mom she was too worried and was a bother. We finally stopped going to see him when she used the restroom and found blood in her stool. She developed ulcers in her throat and stomach that were very painful when eating. After we stopped going to see him we found out all of her symptoms were the beginning of diverticulitis. In 2009 she ended up going to the ER because she was heavily bleeding when she used the bathroom. A diverticula had burst open and it was discovered she has 3 total that had developed. She was taken to emergency surgery. She's suffered through diverticulitis ever since with multiple ER visits. Dr. Castellanos was negligent as a doctor when presented with symptoms. He could have referred her to a gastroenterologist but never did. We had HMO at the time and eventually switched to PPO but it was after dealing with him. For my own case, I developed gastro issues around 12 and realized I had sensitivity to certain foods that lead to a lot of gas and odd noises in my intestines. I felt shy about it as a kid but was worried because I didn't want to sit in class having those noises come from my intestines because well... it was awkward. My side of the classroom could hear my gas issues and I didn't understand what was causing it. When I told him he blew me off and told me to eat more fiber. I didn't bother more about it or ask because I was too ashamed to ask more. Years later I realized I had food sensitivities and that I need to be careful to avoid dairy. All of this to say - I would absolutely NEVER recommend anyone to see Dr Castallanos. My mom could have sued him for negligence but decided not to. Seeing him still in practice now and talking to family about health made me 20 years later have to go back to write this.

I've been a patient at this office for years, and this was by far the most disappointing experience…read moreI've had. I received a call from the front desk today 4/8/2026 after I left my office visit regarding an additional charge for my consult I had paid $120 because I chose to visit their office while my new insurance kicks in, and the way it was handled was completely unprofessional. Instead of clearly explaining the reason for the extra $80 cost, the staff member came across as demanding and dismissive--as if I was supposed to already know their internal policies. At no point during my visit was I informed that discussing my symptoms could turn the appointment into a higher-cost consult. What made matters worse was the tone of the conversation. It felt like I was being blamed for the appointment running longer, which is unfair. Patients rely on medical staff to guide the visit appropriately--it's not our responsibility to manage time or determine billing classifications. There also seems to be a lack of internal communication and organization. If expectations, pricing, and visit structure were clearly communicated upfront, situations like this could easily be avoided. I asked to speak to the office manager because, yes, I had every right to be upset. Instead of taking accountability , apologizing, I was met with defensiveness--and then banned. Banned for speaking up after being treated poorly, advocating for myself. That tells you everything you need to know about how this office handles concerns. There is a serious lack of communication, organization, and basic respect here. If expectations and pricing were explained upfront like they should be, none of this would have happened.

He suggested an ablation procedure in my case, which we completed over 2 outpatient procedures in his office. It has been about a year since that procedure and I'm so happy with the results.
