Hello, how are you? My name is (unreadable). I am completely fine. The nurse and the people who helped, to all, thank you, thank you very much.

I think the cashier that checked me in was very kind. When I waited in the waiting room, it was very short amount of time. The nurse that took me in was very kind and my doctor was very nice and sat with me and talked with me for a while since it was our first time meeting. It was very nice meeting. Thank you.

When I first expressed concerns about my symptoms of my disease via healthcare app text messaging system, the doctor just deferred me to other specialized doctors such as a psychologist because technically my results were within normal range and she said there isn't anything else she can do for me. But at the next follow up appointment, she was more responsive to my concerns and explained my situation better. She ordered a different test to verify my concerns. I feel more validated and supported by my doctor today.

Hi, Dr. Mahmood is a wonderful doctor. She's always very patient and takes as much time as we need. And we really enjoyed coming to her and she's really helping my husband with his diabetes management. My only complaint and it's not about her. It's about the phone situation. It is not uncommon for me to have to wait on the line for 15 to 20 minutes. For somebody to help me to make schedule an appointment. Thank you.

The doctor seemed to get upset when i told her my personal choices about taking a specific medication. After that, the doctor continued on with an attitude towards me and was talking over me every time after that. She wasn't listening to what i was trying to explain to her and continued talking over me. By the end of the consultation, her voice was raised very loud and she was very upset. She didn't seem to care about my opinion or what i had to say. She made me stay longer because she wanted my blood pressure to come down but, she only made it worse by yelling at me and making me feel very uncomfortable. I was not happy with the experience i had. I don't go to her to get yelled at and not have her care about my opinions on medication that will affect me. When i got there i was feeling fine, but when i left i had a very bad headache and felt very anxious.

I've always been satisfied with the service at PIH. And Dr. Mahmood office. She's an extraordinary position. I trust her. She's very thorough. She takes her con to explain and takes times with her patient and never feel rushed and I just admire her so much and I have recommended her to other friends and family.

I just want to say that I changed to Dr. Mahmood. This is the third time I've seen her. I saw the other lady, she's not there anymore, but I did fill out a complaint when I was with her. But Dr. Mahmood made me feel very comfortable, made me feel like I was not being rushed. She answered all my questions. She gave great feedback. I felt like she really understood me and wanted to help me. The other one that I complained about made me cry, and so I just want to say thank you to Dr. Mahmood truly. I really appreciate her care. Thank you.

Friendly staff all around
May 18, 2022
Both Dr. Mahmood and Resident (name removed) were great. I felt heard and optimistic that my thyroid condition will be closely monitored. Thank you to the both of them!
May 17, 2022
I was disappointed with the outcome because she said she didn't treat the condition I have, even though my primary care doctor referred me for that condition, and two other endocrinologists did accept that condition, did treat me for them. So I was a little puzzled about why she said she didn't treat my condition. But just (INAUDIBLE) very competent doctor, just apeared like she didn't want to work with me and maybe I just didn't catch it. That's all I have to say.
May 16, 2022
Very pleasant, informative & positive
May 11, 2022
Dr. Mahmood is very thorough and wants the best care for me. I appreciate her advice and desire to provide me the best options.

May 10, 2022

May 06, 2022
She was very courteous and helpful, trying to help me find out what's wrong with my body. And very concerned, and went over things that I couldn't understand. So she was really okay. So I want to take and just say thank you. I'm done. Okay. Bye.

Excellent doctor and staff. Couldn't ask for anything better. Love this doctor.
April 07, 2022
If I am more than 15 mins late to an appt at your office, you not only cancel my appt, you also charge me a missed appt fee. However, I originally had this video appt scheduled on March 17 and after 55 mins of waiting I had to leave so I rescheduled for April 5. At that appt, again I waited about 50 mins and I couldn't keep waiting. Finally, on the 7th, after again waiting about 40 mins, finally, I was seen. I am expected to sign into a video chat 10 mins before my appointed time and then made to wait as if my time was not valuable. I don't think it's unreasonable to expect the same level of courtesy that you demand of your patients and penalize your patients with fees for violating. Stop giving the doctors such high quotas that we feel like $ signs instead of patients.
April 06, 2022
She was very nice and understanding. Very pleasant and answers all my concerns about my condition.

I just like to say that Dr. Mahmood is an excellent physician, extremely caring, and understanding, and top notch. I have not met a doctor with such a high level of care and understanding and actually, for all of the questions she should be given the top mark, as being excellent and doing an exceptionally good job. I appreciate the good service that she provided and all of the people at the facility. Thank you very much. Good day.

I felt like she motivated me to continue on trying to lose weight on my own first. But also is willing to run labs and go the extra mile to know more. I really felt she cares not only for me but for her patients.

I hope PIH decides to bring back Cigna insurance, otherwise I will not be able to go to PIH network.
October 26, 2021
This with endocrinology and it's extremely crowded, and It's really hard. When I originally called, they were going to give me a get me in until March, and then I texted my doctor my GP, and she eventually got me in obviously a lot sooner but, you know, the wait time to get in and do regularly is crazy. And so, something needs to be done. They need to get more endocrinologists or something because I they got all those diabetes people that have to be seen.
October 20, 2021
great Doctor
October 14, 2021
I made a mistake on rating, the staff. I would give them a 1 and I already expressed my concern to the people involved.
October 14, 2021
She is one of my favorite doctors! Very patient, kind, understanding and a great listener. It's a pleasure & honor to be one of her patients!! I'm very lucky!!

Yes, I highly recommend Dr. Mahmood. She's a... I feel she's an excellent doctor and helping me to, you know, providing me the correct medication and all and advice, and she has a best interest in me and my health. Thank you.
October 07, 2021
No one told me I had to register downstairs before going to see the Dr. I was in the waiting room over an hour before I found out I had to register downstairs.
October 06, 2021
Dr. M is honest, straight forward. She listens. Always supportive and encouraging.
October 04, 2021
To improve I would try to answer the call more faster because when you call, sometimes you're on the phone for 45 minutes, waiting for them to answer.
October 04, 2021
She is everything I hoped for - caring, competent and attentive.
