not much except he is there when I need him.
September 09, 2022
I've been having bad experience with appointments. I had a phone appointment scheduled at 10am they rescheduled it without notifying me.
September 06, 2022
I want my (name removed) back. I want her back. I'm tired of this new doctor. Bye.
August 31, 2022
I was very pleased with Dr Kung, very soft spoken, patient not in a hurry to leave the room went over everything with me I'm very happy with him
August 26, 2022
The nurses who are in charge of drawing blood are very slow, I waited an hour for them to attend to me, I think that there in that office they need to improve.
August 25, 2022
He did not hear me out about my concerns. I asked if I can get testing done to measure my hormone (Testosterone, DHEA, Androstenedione, estrogen, progesterone, luteinising hormone, follicle-stimulating hormone, and cortisol) levels because the topical treatments that dermatologists have recommended over the past year have not worked after trying each treatment for 1-2 months. He proceeded to tell me "Well hormone levels usually aren't checked for acne. Let's just refer a dermatologist". In that moment, he could h ave just said he doesn't know much about the correlation so a dermatologist could possibly authorize hormone screenings. I was insistent on wanting testing done because topical treatments and birth control did not help my acne despite giving it time to do so, yet within the 2 minutes that he spent with me with barely any eye contact, he did not hear me out at all. He made me feel like I was a waste of his time for how short the interaction was.
August 22, 2022
The wait time for the lab was 45 minutes. That is unacceptable. The nurses drawing blood seemed inexperienced. I had to have both of my arms pricked, because the first attempt failed. Could have been my vein that was the problem but how they went about it was awkward. They weren't communicating, which made me a little nervous. Furthermore, I shouldn't be forced to put on a mask upon entering the building. If I was sick in any way, I would just reschedule my appointment. Enough people are vaccinated, we've reached herd immunity, it's been over 2 years, people have moved on. Masks make my anxiety worse and I shouldn't have to explain my personal reasons to a security guard or receptionist!

I tested positive for Covid-19 on a home rapid test. I called the office on Monday & got an appointment the very next day. Dr. Kung called me about an hour ahead before my appointment. He understood my condition & prescribed the right medications that I need it. I feel better & appreciate he's quick, caring, & professional response to my needs. Thank you! To all PIH staff that help to achieve my quick recovery.

Very professional staffs
March 17, 2022
I am always pleased with the care I receive, doctor Kung and his nurse (name removed) are great
March 02, 2022
Felt very rushed. Talked to the doctor for what felt like was less than 10 minutes. Felt rushed and like he was in a hurry and was very dismissive of what I had to say and at a point scoffed at my request for a referral.
March 01, 2022
I didn't have the doctors full attention on me. He didn't give me a fully thorough physical check. He also didn't check me for Hernias or offer a Colonascapy check. I don't think I'll be returning to this Doctors office with it being my first time here.
March 01, 2022
Hi. I talked to Dr. Kung and I told him I had a fever, my eyes are all pink, I have pink eye, and a sore throat. And I thought maybe he'd call in antibiotic. So 2 days later he called in ... well he called in that day. He was good about that. He called in something bout arthritis. I still have a fever. I still have a sore throat and I'm feeling like crap. I just wish he would've listen to the ... what I was saying a little bit better and called in an antibiotic for me because I'm still sick. Thanks. Bye.
February 23, 2022
It was just over the phone for my physical results The lab results I wish I would have a paper copy I know in the past years they've sent the results and I wish they would still do that
February 16, 2022
I am always seen in a timely manner. And the staff is very friendly and helpful. Dr. Kung always listen to what you have to say, very professional and compassionate.
February 16, 2022
Been a patient of Dr. Charles Kung for, at least 15 years. And have been very satisfied with his care. He's an excellent doctor. Thank you.
February 16, 2022
No problems, great visit
February 07, 2022
You're doing pretty well. The only problem we have is the cost of the medication. It's just getting out of control. I'm on a fix income and it is getting hard to pay for all this stuff. So, I don't know if it's possible to do anything with that, but you need to try. My name is (PHI removed).
February 02, 2022

Very satisfying feel much better
January 25, 2022
So far great experience. Thank you.
January 21, 2022
It would be nice that if they say the lab is going to be open from Monday to Friday, from 7:30 to 3:30 or 3:00. It would be nice if they maybe send a message. If they know there's Labs pending for patients, if it's really Irritating. When you have to take time off from work, and the lab is closed and they don't tell you until, like, 10 minutes while you wait. That's it. Other than that. I love my doctor.
January 19, 2022
Is not my regular PCP therefore as I was added to probably a full schedule, that would explain why he seemed harried.
January 18, 2022
I was not given any instructions as how to treat my injuries, I had to ask if I can get some medicine for the pain, doctor had me taken many X rays but did not ask me back to give me a diagnosis, I went back to his office to which the nurse said, "your prescription has been sent to the pharmacy"; it was then I asked if I was going to have a diagnosis, if I had a concussion, or what? 25 minutes later I had to reminded her that I was still waiting for an answer, I was told "you're okay, come Friday for a follow up" I slipped on an ice surface, hit the back of my head and back very badly, my neck hurts a lot, also where I hit my head, been 48 hours since the accidental fall, and not feeling any better.

I started with Pioneer Medical Group then it switch to PIH and the doctors from Pioneer Medical Group, I haven't really been happy with any of them thank you.
January 10, 2022
Good attention and follow-up
December 01, 2021
Hello, my feedback is that Dr. Kung was very interested in my well being and following up on my diabetes and giving me some good fresh tips... For my... diabetes 2. And he sounds concerned about two things I have to say. And also... The other appointment with Patel was awful. Dr. Patel had no concern about what I have to say. He said it was just a bruised tendon, when I've had that ball on my foot for 2 years. So, yeah, Dr. Kung is an excellent doctor and he's a good listener and I like the way that he pretty much concerned about what we have to say about our health.
November 22, 2021
Well, first of all, I would like to say that it took me several calls to finally be able to get a message through to the doctor. to be able to finally get an appointment as far as my medication, and my services I finally got an appointment. When I got there for my appointment. They didn't call me in for 20 minutes after my appointment time. It was in the morning 8:30 8:40, something around there. I wasn't pleased about that. The doctor came in he check me out a little bit asked me a few questions but as usual, they be on schedule he didn't spend no more than 10 15 minutes with me, but I guess that's all was necessary, you know, but I mean I was with Pioneer Medical and now I'm with PIH so it's a little different. I've been a patient for over 20 years. So I'm still you know, trying to get the services together if not, I'm going to look elsewhere for my Care. Thank you.
