Brendan Cerk MD is a rheumatologist who chose his field after growing up watching his mother suffer from the debilitating impact of rheumatoid arthritis. He completed his fellowship training in rheumatology at LA County USC medical Center, where he gained experience treating patients with the most severe and complex rheumatologic conditions. Dr. Cerk believes that the smallest detail may be the key to making the correct diagnosis, so he takes time to listen to everything his patients tell him and gets to know them so he can make them feel better.

Dr. Cerk has traveled to Ecuador for a medical mission and enjoys playing beach volleyball.

Relaxed and pleasant doctors visit
September 07, 2022
Very professional and thorough.

This is not actually regarding the doctor himself, it is actually more about the x-ray technician I was sent to go see right after. The technician was very arrogant and he got upset when I asked him to go ahead and give me a, I guess, whatever, the covering for the x-ray. 'Cause he just wanted to give me a small one. And I said, no, I wanted a large covering and he became upset, and he even questioned if I've ever had an x-ray before, where did I get it? Why would... why would I ask for something like that? So I had to ask him multiple times to give me the covering to protect myself from the rays of covering. Very arrogant, that male that helped me that day.

I just want to say a great big thank you to Dr. Cerk for taking the time to explain my mom's care. Grateful for his sincerity and kindness towards us. There should be more doctors like him. They can learn a lot from him when it comes to patient care.

I came to see Dr Cerk after seeing a different Rheumatologist for over 4 years. I really appreciate Dr Cerk's patience with me and broader approach to treatment options.

Thank you,...the doctor's office was superb, a prospective patient could not ask for more. But, when it comes to PIH Health software entanglements when trying to conquer the task of completing the online pre-registration forms, you may want to reach out to that 3rd party web developer and ask them to put in an edit feature for pertinent information if not all questions. Secondly, it would seem that in any doctor's office when it comes to the MR staff when a patient was just seen yesterday and calls the office the next day, and he reminds the MR that the doctor mentioned a NSAID, and would like the doctor to call it in, why would it take maybe until the close of business >>> 2 days before that request is honored while the patient is in pain, rather than the MR going over to the doctor's box, dropping the request in, or catch them on the fly and mention the request to them,...simple.

Dr. Cerk asked a lot of questions which I liked. He listened to me. He made a lot of good suggestions. He did good testing. Overall, he was excellent. I've never had a doctor like this that was very concerned with my health and wanted to take care of me. The X-ray person was oh my God, she was so funny. I enjoyed your staff. Thank you.

The entire staff there was very nice. From each place I went to for this visit I was treated well. At check in / weight in / dr office / x-ray/ blood test.
May 27, 2022
Dr. Cerk was absolutely fantastic. He took the time to really listen to what I had to say, asked appropriate clarifying questions, answered all questions I had, and created a detailed plan for my care the included referrals to appropriate specialists, as well as follow up with him. I feel that he is truly trying to work towards an accurate diagnosis and plan of care, and I look forward to continuing to work with him.

April 26, 2022
Very helpful explained everything
April 21, 2022
As it was my first visit, I will reserve referral to family or friends until I've know Dr Cerk for a while longer. But I was very favorably impressed this first time.
April 20, 2022
My appointment was handled in a timely manner
April 14, 2022
I really appreciated Dr. Cerk's attention and (INAUDIBLE) on my labs. He is a very good doctor. We did experience some difficulties with the landlines at the office. However, when we tried our best to be connected, sometimes difficult.

Dr. Cerk explained the different medicines available for osteoporosis in detail very clearly. He also gave me articles to read on the different medications/ treatments that are in the market. He is new, but I am sure he will be an asset to PIH.
April 07, 2022
Was a bit uncomfortable my usual doctor is off on maternity leave be Happy when she is back. He went into my file saw some issues did not explain clearly just said enzymes were up slightly needed chest x rays,CT scan and blood test which scared me quite a bit
April 06, 2022
It was a tremendous, wonderful experience being seen by Dr. Cerk. He took his time, he answered all my questions. He did not speed up the visit, the exam. He took his time to explain everything to me, and I just wish that more doctors would do the same, but as (namre removed) is, they're both wonderful. Thank you.
April 05, 2022
My number two question, I fumbled my phone and pressed the wrong button. I don't even remember what the question was, but I was very happy with Dr. Cerk, and all his abilities to listen to investigate what might be the issue. Thank you very much.
March 31, 2022
Hey, spoke to me like a doctor and I was very impressed with him. He answered the questions I asked. Thank you.
March 29, 2022
You know, when I finished up I had kind of- I wasn't feeling too well. I had low blood pressure and (name removed), the PA asked me to make an appointment for two weeks from now and 30 days from that date. And I said, I wasn't really feeling well and I couldn't do it. And she said it would be better if I would do it before I left. And I said, I couldn't. And I just thought that, you know, she should offered to do it for me. I wasn't feeling very well and I had a, I was lightheaded. She had taken my blood pressure. It was low and I just, you know, I wanted to see Dr. Cerk in two weeks to get two injections, one in each knee. But I just, I just felt so low. I couldn't do it and I asked him if I could see him and he said, yeah, you know, let's get- I'll get an appointment

March 21, 2022
the doctor spent ever little time with me. he didn't even check my heart beat. never examed me just asked question and checked my blood work. he left the room and then came back and said I guess I should check you hands at lease. I could of done this visit over the phone. i was charged $60.00 for this visit it was a waist of my time and money. after the doctor left the room I waited 15 minutes before assistant came back to let me go. service was not good at all.
March 21, 2022
Dr. Cerk and the assistant were knowledgeable and most importantly caring.
March 09, 2022
First visit with Dr Cerk who was filling in for my doctor who is out on maternity leave. I was impressed that Dr Cerk was totally aware of reason for my visit. He was friendly & helpful. I do wish the Rheumatology Orthopedic Dept had better phone service - very hard to get through on phone to make or change appts - long waits or no answer at all - offer to leave # for callback is useless - doctor, staff great - phone service terrible
March 09, 2022
He was excellent. Alright, I'll have this thing on this. I have my cellphone is calling from the doctor's office. Okay. No, I couldn't get a hold of him. Alright. Bye.
