Dr. Oang knew he wanted to pursue medicine growing up in his native Cambodia. “I was sick a lot during grade school, even missing vacations with my family. So, I decided to be a physician to take care of myself,” he says, adding that “Internal medicine offers a broad base of knowledge, which enables me to take care of patients with all different medical problems.”

Dr. Oang survived Cambodia’s brutal dictator Pol Pot and the Khmer Rouge regime, responsible for killing more than a million people in the 1970s. Today he likes to vacation with his family.

July 08, 2022
Dr. Oang is a caring and respectful person of his word; following through on some issues and calling personally with test results.
July 07, 2022
The phone appointment system is horrific!! I have had to wait up to over an hour or call back several times just to get an appointment to see my providers. I have even been hung up on several times. Even after waiting 45 minutes once last week with 12 minutes left to wait I was hung up on. I have tried the call back system and have not received call backs. I have tried the nurse contacts to no avail. Sometimes I just don't do the necessary follow-up appointments because I know I will have to wait too long on the phone, or they won't call me back. I have tried to find out the best days and times to call and have nothing. I have referred my relatives to these excellent providers but a few have sought care elsewhere, due primarily, for not being able to get through for an appointment or to get an appointment for several months. Something needs to be done about it. I changed from other HMO's because I thought they were bad but PIH is by far the worse.
July 07, 2022
Policy and protocols are to be a guideline and never to be used in a penalizing manner. I had a situation of going to the wrong location for the visit and as soon as I recognized it, called the office out of courtesy to alert them that I was in route and should be there within 15 minutes (called 5 minutes passed appt time). Two conversations later as I was enroute I was told I would need to reschedule because of policy for a wellness visit. I informed them that I was one minute away, and I would come in. Bear in mind that I waited months to have this appointment and I told them that if I didn't have the wellness exam, that would be fine, but I needed to have my bloodwork done or it could become an issue of liability due to lack of care. When I arrived, it was obvious that the front office staff had been briefed. I was told repeatedly that the policy of 20 minutes late was strictly enforced (check in time was 3:21 p.m. and I called them at 3:05 p.m. on my way from Putnam location). The receptionist stated twice that as a courtesy to me they would see me this time. Her demeanor was punitive, not considerate or understanding, unwilling to hear or accept what I had to say. As soon as I was signing in, before being called in, back office was calling my name. So, I guess they emailed her as soon as I got to the counter anticipating that there would be some type of confrontation. I have a history of working in the medical industry as a front office supervisor and am well aware of protocols, policy and excellent customer care. The goal is to serve the patient and deescalate situations not to be unbending and proof your point. Sometimes things happen and there needs to be compromise! A wellness exam is greater than twenty minutes, so even if there was a review of the records and lab work ordered I would be accepting of that. However, because Dr. Oang is understanding and considerate and we have a good rapport, he did the full exam, caught up, and he reminded me that whenever there is a concern to email him directly. His response kept me from pursing another medical office and doctor. Thank you for exercising your care for patients you serve. My prayer is that staff is reminded that the health industry is one that focuses on serving, which requires kindness, patience, compassion, knowledge, and skill.
July 06, 2022
This office is very, very busy and the only way that I did give them an 9 or 10 satisfaction is some type of a problem to get appointment easy enough. This time, I was lucky. Thank you.

I don't want another doctor that is just awesome. He is good. He treats you with respect. And he listens to you. And like I say, he is hard a good doctor's hard to find. So we just love him and he takes care of my family as well. Thank you. Bye. Oh, maybe appointment scheduling. I know, he's kind of busy. That's why. But, but He's awesome. Thank you. Bye.

I'm so happy that Dr. Oang is my physician. I have faith in what he says...even if I don't want to hear it!
