I had trouble finding a care provider who can help with my PCOS but she sent me to get lab work and ran some tests. I'm truly happy with the results and felt taken care of!

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.

Dr. Gin is a great Doctor who is professional and takes time to listen to his patients. I am also a…read moreclinician and can appreciate when a medical team has good bedside manner. I had to change my PCP from OC to LA county and happened upon Dr. Gin's office in my neighborhood. He has helped me jump through a couple of hoops to find which medications my insurance will cover and even submitted a pre-authorization the same day that I was in contact with him. Kevin was also great, I'm usually a hard stick and he got my blood drawn in one try! I always appreciate when they don't have to fish around for my vein. I highly recommend Dr. Gin and his medical team. Thanks for the support Doc!!

Truly an inept medical facility. Had scheduled an appointment and waited 50 mins past that time…read more Was finally let in and waited an additional 30 mins in one of the rooms all for a basic physical I effectively never received. I stuck my head out and asked if I could just get my blood drawn and they finally called me out 10 mins after that and then I left. This is the second time I have had to wait far past my appointment to be seen and given minimal attention. Now I need to call two weeks after the appointment for the results of the blood test (they were supposed to call within a week of getting results) and I can't get through to anyone. Remarkably ineffective and truly frustrating. I would not recommend this practice to anyone in its current form.

The care you will receive here is above and beyond. The quality care you will get as well worth the wait in the waiting room. They take the time with each patient to make sure that all issues of your appointments are resolved. Maximum stars are 5 but they're definitely a 10 star rating ‍ ‍ Wendy W

Update: I received a letter in the mail from the office stating that they've tried to reach me…read moremultiple times to discuss an urgent matter regarding my blood work. I have not received a single phone call, happy to show my phone record for proof. And if it was such an urgent matter, even if they did call, you'd think that they would leave a voicemail. But nope. No calls no voicemails. I tried calling today at 12:30 PM and was sent to a recording that says they are now closed for their lunch hour which is 1 to 230. The voice recording says it, the letter says their lunch hour as 1-2:30. So why am I getting their automatic record recording if it's 1230 when I'm calling?! Regarding my blood work, I first called them once my results were posted and said what happens next? Because the sole purpose I went to this doctor was for them to help me understand what was going on with my blood work. The receptionist said and I quote "if you didn't receive a call from us that means there's nothing for concern with your blood work and I don't see any notes in your profile" so you're gonna tell me that they were just going to never reach out to me for a follow up if my blood work looked fine? That doesn't mean my concerns and my health issues are resolved! So now months later, and I'm getting a letter in the mail saying that they've been trying to reach me. And they haven't! And every time I try to call them and ask WTF this is, I get an automatic recording during their actual office hours, saying that they are closed and you can't even leave a voicemail. I hope they see this and call me ASAP because they are supposedly keeping vital medical information from me.

I had the privilege of working alongside Dr. Jurdi during my rotation at Advocate Family Medicine…read moreClinic, and I truly cannot say enough good things about him. As a third-year resident at San Dimas Community Hospital, Dr. Jurdi embodies everything you would hope for in a physician and mentor. He is incredibly warm, approachable, knowledgeable, and genuinely invested in the people around him. He created an environment where questions were welcomed and learning was encouraged. He never made me feel judged for not knowing something; instead, he challenged me to think critically, dig deeper, and become more confident in my clinical reasoning. What stood out most was how much he cared about his patients. Every interaction reflected his compassion, patience, and commitment to providing the best possible care. He took the time to listen, build trust, and make patients feel comfortable and heard. It's easy to see why his patients think so highly of him. As a mentor, Dr. Jurdi consistently pushed me outside of my comfort zone in the best way possible. He encouraged me to take initiative, expand my knowledge, and develop skills that will benefit me throughout my medical career. His teaching style is supportive, engaging, and inspiring, and he has had a lasting impact on my growth and training as a future physician. I would also like to recognize the entire team at Advocate Family Medicine Clinic. The clinic has an incredibly welcoming atmosphere, and every staff member and physician I interacted with was professional, kind, and dedicated to patient care. It is clear that the culture of teamwork and excellence extends throughout the entire practice. Thank you,Dr. Jurdi and the Advocate Family Medicine team, for such a positive and memorable experience. Any patient would be fortunate to have Dr. Jurdi as their physician, and any medical student would be lucky to learn from him.
