All good

Dr Herald is thorough, professional and caring. He treats the whole person.
January 23, 2026
I was unhappy that I was not able to book my appointment earlier because I was told that my original doctor was no longer my doctor because I hadn't seen him in awhile.
January 13, 2026
Dr. Herald was very professional, knowledgeable, good listener, explained every subject very clearly. Good manners , friendly approach. Highly recommended.

The staff providers are great. Great interaction
December 30, 2025
Okay, I was, I have some difficulty taking my blood pressure and I also have some difficulty with the instructions because the medicine is specific to my heart. But I understand what he told us and I'm just doing my very best to follow that. Thank you.

Hi, Dr. (name removed), he was really, really great, really listened to me. I would recommend him to my family and friends. And thank you so very much, doctor. Bye.
December 01, 2025
This was my first time meeting Dr Herald. I immediately liked him as my new cardiologist. He was very thorough and efficient. He recommended that I have an echocardiogram done since he heard my murmur and it had been a few years since my original one . He wasn't overly concerned; but taking precaution.I appreciated his concern and his staff took care of scheduling it for me. The staff in that office is great; friendly and willing to assist. Thank you!
November 21, 2025
I'm very pleased with the way Dr. Herald listens to me when I come in. I am impressed with his knowledge and he was very helpful in giving me some additional things that I could do along with affirmation of things that I had been doing. I very much appreciate Dr. Herald and am looking forward to the continuing relationship with him.

November 04, 2025
Very good attention.
November 04, 2025
This and all appointments at PIH is definitely hard to make, get into. If I really needed to see a doctor due to illness, I'd have to go to urgent care. However if I was planning my yearly checkups or follow ups scheduling 3 months ahead of appointment is OK
October 27, 2025
Pih doctors are great
October 23, 2025
It's the first time I had an appointment with Dr Herald. I was pleased with his demeanor and the appointment was brief. I enjoyed his confidence in my judgment. A first time, I think should be like a consult with in depth medical review. I look forward to our subsequent meetings.
October 23, 2025
From beginning to end First Class all the way.
October 20, 2025
Hello, my name is (PHI removed). Regarding Dr. Herold's office, I would definitely give everyone a 10, from the front desk to the doctor himself. They are all very professional people, and I have received wonderful care. Thank you, Dr. Herold. Bye.
October 20, 2025
I try to be proactive when it comes to my health and I felt I was listened to and had a good consultation. I feel very good with recommendation and moving forward.

October 13, 2025
Thank You. To the staff and Dr. Herald.
October 07, 2025
Dr Herald, (name removed) (his nurse) and (name removed) (front office) were all exceptional.
October 06, 2025
The nurse that took my vitals could have been a little more friendly and not be in such a rush.
September 30, 2025
I was very nervous going there and the nurse that I had was awesome. He is a very, very nice, very reassuring nurse. The doctor was awesome and I was happy. Thank you, you guys. That's it.

Met Dr. Herald for the first time. He was very professional and answered all my questions.

August 19, 2025
I appreciated that the doctor was very kind and understanding for my needs to move things forward sooner to help me with the procedure that I need to get done.
August 05, 2025
Lupita was great, she was very friendly and tentative, Dr Herald was great and listened to my concerns and he gave me what I was looking for as far as imaging and I do think he has my best interest when it comes to my health. Only complaint if any was how long it took to get my appointment, but I understand now because the service is great.
August 05, 2025
Dr Herald and the nurses in the office were all professional and very kind. I feel like I was heard, and I'm comfortable with the assessments he wants, as well as with the follow ups suggested. I feel like he treats the person without bias, and that's still pretty rare in medicine.
August 01, 2025
They read all my pre-prepared notes and questions, and answered each one. They were patient and understanding and its very appreciated!
July 29, 2025
Yes, I was very satisfied with Dr. Harald's visit I had with him. I went into the office on July 29th and I had palpitations and he was able to diagnose and even had to send me to the ER to get some medication and he acted quickly and promptly. He was very understanding, listened to your needs, The office staff was great, came to see me when I was in the hospital for the two days or three days, and I would definitely keep going back and recommend him.
July 29, 2025
Dr. Herald has been wonderful and I am so grateful and blessed to have his as my cardiologist. I tell all my family and friends about him and highly recommend him to all
July 24, 2025
They were very compassionate and kind.
July 17, 2025
They went over my medical records that I had at PIH but my past medical records from other hospital that have deferent IPA's other then PIH are incomplete. Do you need me to help you out with getting medical records from other hospitals or doctors offices or do you need just the names of hospitals or doctors and dates that have treated me in the past ?

Dr. Herald is a brilliant young surgeon with a big heart and magic hands. He is my hero because I believe that he has improved my longevity and the quality of my life and I'm deeply, deeply, deeply happy and hopeful that I will be able to live in peace and be able to share with my family all these blessings. I definitely recommend Dr. Herald and for me it will be an ongoing process, a work in progress but with his help I think that I have a bright future. Thank you so much.

April 28, 2025
Great experience professional service from check in all the way thru with people who took care of me.
April 24, 2025
The first nurse that attended me was very nice and took good care of me
April 24, 2025
I had a good experience at the office. They were able to help me. They were very nice. I think it would just have been nice to have the ultrasound on the same time instead of having to come back at the same day when it looks like they ordered it, even though my first CAT scans were normal. But, yes, that's it. Thank you.
April 22, 2025
got in and out within 1 hour no waiting
April 17, 2025
Kindness, punctuality in serving me
April 15, 2025
Although I had an early appointment, the office was on time and very courteous and efficient. Dr. Herald was easy to speak with and very focused on what was needed for my upcoming surgery. I highly recommend.
April 11, 2025
I'm just saying that it's the language that I don't speak English and that's all that Spanish I would like to improve for Spanish.
April 11, 2025
Dr. Herald was very kind very patient with our questions very knowledgeable and going the extra mile
March 31, 2025
Nurse (name removed) was very thorough and patient taking my vitals and EKG.
March 27, 2025
Hello, this is (PHI removed). You had called me and I was putting 222 because I thought that said yes. Then I actually listened to the whole recording and I wanted to press all fours, all very good. Every question you asked were fours. And then the 10 at the end, that was great. And so sorry about that. There's a bunch of twos in there, but I actually meant fours. Okay, bye. And you did a wonderful job. Thank you.
March 25, 2025
Good but very fast
March 21, 2025
He's a specialty doctor and it's the first time I met him. So I was good with him, but I would like to take another evaluation maybe the next time I see him, see how things work out. And I was very happy with him, that's all I can say. Thank you.
March 17, 2025
I liked having the doctor explain things to me and that went well. I don't like having to wait a month or more than a month to be fitted with a monitor to check why my heart is beating erratically. I think you should do something about the wait time for the heart monitors that you wear. Thank you.
March 13, 2025
easy safe parking
March 13, 2025
I was able to get an appointment easily. Dr Herald listens really well. My case is unique, and at first, I was worried that I would not be received as well, but he made me feel comfortable and heard. He seems to really care about his patients. I would highly recommend him.
March 10, 2025
