Patient Reviews

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.
September 29, 2021
Staff and practitioner were amazing. Very pleasant and professional. Dr. Mahmood is an awesome doctor.
September 28, 2021
I always do the online checkin and feel that having to wait and checkin again when I get to the lobby is absurd. Please change this additional checkin policy, I already have my medication list as it is contained in the FollowMyHealth App.
September 28, 2021
Very smart Doctor,helped me out tremendously, very happy!
September 23, 2021
Dr Mahmood is a great doctor. She has improved my health and Quality of life. Highly recommend her!!
September 22, 2021
Dr Mahmood cares for her patients well being. She has encouraged me to health and I am very grateful.
September 21, 2021
the doctor was very informative and answered my questions.
September 21, 2021
The only problem that I have is that when I call to make an appointment or anytime I want to get in contact with the office. It just takes forever. I'm always like the 7th caller in line and I'm on the hold for like 20 minutes and I still hang up because it takes forever for anybody to answer when I called to make an appointment.
September 21, 2021
Dr. Mahmood & her staff are always very kind & pleasant. They listen to my concerns.
September 21, 2021
Couldn't make an appointment because they weren't making appointments for 2022. Seemed odd I waited more than 10 minutes downstairs in the urgent care waiting area even though I had previously registered on line. It was crowded and did not like waiting in that area. What is the point of registration early?
September 20, 2021
Would have liked to have had my visit last longer to go over my treatment.
September 03, 2021
Waited 25mins to be called
September 01, 2021
Recommended medicine too expensive. Need to consider patients income. Most older persons on fixed income .
September 01, 2021
Dr Mahmood is the best endocrinologist I've seen so far and I've been seeing endocrinologists for the past 30 years.
August 26, 2021
They all ... this was my first time meeting her. But I liked her and she's very kind and considerate to me. I don't get that ... that often, so when I do have doctors that care, I care about what they say to me.
August 26, 2021
She is a awesome Doctor. She cares for all her patients and is very attentive to all her patients needs. She shows a lot of empathy for her patients needs. Her staff is also very caring.
August 26, 2021
Dr. Mahmood and all her staff are really great caring people. We are super happy with this office
August 25, 2021
This was my first time seeing this provider. Dr. Mahmood was patient and kind. She asked many questions and listened carefully to my answers. She was very thorough. Explained exactly what tests she was ordering and why. I like best that she went outside the realm of Endocrinology in her exam. She looked closely at my history and past lab and xray results and touched on some women's health issues that even providers I see frequently don't address!!! I would love to have her as a Primary Care Physician!! Her office staff was very efficient and friendly.
August 20, 2021
I went in nervous and came out so happy and thankful to the provide fir caring.
August 18, 2021
Dr. Mahmood is awesome! Unfortunately, I have more trouble trying to get through to her when I need her. Her staff guards her better than the White House guards do with their staff! PIH has really become about the money and not the patient care as it was before. She referred me to a specialist and I have to wait 2 whole months before they can see me! I'll be lucky to be alive in two months. I'll have to seek help elsewhere. Very disappointed.
August 11, 2021
The Dr. , and the stuff are very nice, and professional.
August 09, 2021
Dr. Mahmood gave me very detailed facts so that I now understand the gravity of my situation and will follow through with all related protocols.
July 29, 2021
I like the doctor but the wait time to see her from check in to actually seeing the doctor was ridiculous. Everyone's time is precious and for both appointments this year I had to wait for over 1 hour in the exam room before the doctor came in. How can this be acceptable? How can this be remedied???
July 27, 2021
Dr. Mahmood is very caring, respectful, thorough, timely, professional, and most important approachable.
July 26, 2021
Dr. Mahmood is an amazing physician. Her manner and care is exceptional. PIH needs to keep her forever. she is very thorough, doesn't miss a thing. It's obviously that she genuinely cares about my health and wellbeing. her follow through is great!
July 12, 2021
Hi. I am an African American women and constantly being told that my BMI exceeds where it should be. Speaking with others we know, we all feel that BMI was designed for a certain group and doesn't entail specifics to the African American community. So it'd be nice to have BMI better explained and from the standpoint of providing details on how it was developed and if African Americans were part of that study. Thanks.
June 28, 2021
I waited 2 hours before I was seen by the doctor. The doctor spent 6 mins. with me and yet you charge me the full office visit co-pay! this is unacceptable and needs to be addressed with your physicians staffing! Why would I recommend this to someone else??
June 28, 2021
The moment you walk in the building you are greeted.
June 22, 2021
I felt that my concerns were heard and a clear plan of action was made.
June 16, 2021
Dr. Mahmood spent a lot of time with me to go over every detail of the reports and I felt I had great service from her.
June 15, 2021
She was able to video conference with me due to a tight schedule on my part. I had an allergy shot later in the day so she accommodated me so there would be no conflict.
June 11, 2021
All was great except the waiting time in the exam room to be seen. Nearly 50 minutes after checking at lobby and having checked in online.
June 10, 2021
I had a telephone appointment and I was told I would be called back by a staff member to set up my next appointment, that never happened. I also can't pay when pre-registering the day before for my appointment which makes it a hassle when at the end I get billed. I rather pay beforehand
June 08, 2021
Great Experience as always every time.
June 07, 2021
Dr. Mahmood is an exceptional doctor. She is the best I've had it in any of the doctor expertise. I highly recommend her, and she is very knowledgeable. I love being her patient.
June 07, 2021
Doctor wasn't going to give my hurt wrist a physical examination until I told him to he was just going to refer me to ortho and send me out with nothing for the excruciating pain I had I'd never schedule with this doctor again
June 03, 2021
June 01, 2021
Dr. Mahmood is very thorough and explains everything well.
May 20, 2021
Hello. the lady, we have a good one and tournament down there at the Doctor's office, they had could help us in there. We did a good job. and I like the doctor and I'll call her employees and Had a good experience, and it's already working today.
May 18, 2021
I am more than satisfied with the help and treatment that PIH administered to me.
May 12, 2021
She is very concerned about my health and goes over everything. Very good Dr
May 12, 2021
Both the doctor and her office staff are extremely professional, courteous and treat you as a person.
May 04, 2021
there are great people working at that office.
May 04, 2021
Dr. Mahmood is very kind and courteous. She really listens to what I have to say and answers all questions.
April 30, 2021
THANK YOU, Dr Mahmood for A-L-L my progress!!
April 29, 2021
Dr. Mahmood was excellent! I am legally blind. My wife is very hard to please with Doctor's that have seen me because of the mistreatment from Kaiser Permanente. My wife was with me the entire time and continued to say, "Dr. Mahmood is excellent, polite and very attentive to your Medical history. She's GREAT!"
April 19, 2021
Staff communication seemed to be lacking. I waited over a half hour in the waiting room before I went and check on my status. Somehow, I had been lost in the system.
April 16, 2021
Love Dr. Mahmood! She is caring, patient and always listens to what you have to say. It's always a pleasure going to there doctor visits!
April 16, 2021
Dr. Mahmood is a true professional. She asked various questions to diagnose my thyroid issue, as well as, provided a thorough explanation of hyperthyroidism and my next steps. Dr. Mahmood Is a great asset to PIH Physicians. Thank you!
April 02, 2021
Very good experience. Dr.and staff took very good care of me and my concerns. Keep up the good work.
March 30, 2021
The wait time was completely unacceptable. My appt. was at 10:40. I arrived and checked in at 10:30. I waited in the waiting room until 11:15 and finally went to the desk to question why I hadn't been seen yet, although 3 people who arrived after me had already been called in. They looked at their computer and said I was in a room. Obviously, I was not. When I finally got in a room at 11:20, the nurse told me there were still 2 patients ahead of me, which meant another half hour of waiting. UNACCEPTABLE! A patient's time is as valuable as the doctor's time. Appointments should not be made so close together if doctors cannot keep up!
March 24, 2021
Wonderful physician
March 24, 2021
Yes. Seeing the doctor was excellent. I would recommend ER to anyone. She's very very good doctor. Excellent. Excellent. Thank you.
March 24, 2021
I would like that I could get through on the telephone and make an appointment. You have to wait a long time. It's not. I don't have that much time to just sit on the phone and wait for somebody to answer. So I I wish that they get more people there or something. Otherwise, it's okay. Thank you.
March 24, 2021
Dr. Mahmood has always given me the best of care. However, the last visit I had with her which was this this week. She was running behind and was somewhat rushed and I did not was not able. She is and enough time with me. I didn't know she wasn't coming back in the room and I didn't get to discuss some one troubling matter. If sir.
March 24, 2021
Staff staff and the doctor were great
March 24, 2021
Thank you nurse's, receptionists & doctors for all the sacrifice & work during this pandemic.
March 23, 2021
I trust Dr. Mahmood, however, this is the second virtual appointment I have had with her and my wait time has been over an hour on both occasions.
March 22, 2021
I would say the doctor was extremely helpful, kind, gave me all the information I needed and I would recommend doctor to my family and friends. I thank her for her service. Thank you.
March 18, 2021

Attentive, knowledgeable, caring & responsive. Doesn't miss a thing. Looks over everything and follows up accordingly. Dr Mahmood is one of the best Doctors I've ever dealt with. It's a pleasure to speak with her.
March 05, 2021
Very friendly informative what a great personality and caring doctor. She listened to me and explained the treatment in a way that I could understand. Love that she brought a laptop and sat with me to discuss my care.
March 05, 2021
Dr. Mahmood was extremely thorough, explained everything to its fullest, read through results I provided thoroughly, answered all of my questions, submitted all tests she thought were important, overall I completely trust her and looking forward to see her on next appointment.
March 04, 2021
Very rushed appt. had so many questions to ask but was derailed, too much of a watch and wait scenario, rushes through all clinical results.
March 03, 2021
Dr Mahmood is very attentive and encouraging. I have much confidence in her.
March 03, 2021
I feel very comfortable with Dr. Mamood handling my health care!
March 02, 2021
She is the best Endocrinologist ever I met who is most competent.
March 02, 2021
Great patient care
March 02, 2021
it was difficult to schedule an appointment I had to wait 3 months
March 02, 2021
I arrived 25 minutes early for my appointment so I had enough time to check in. I was asked to sign in and sit down because there was others in front of me. I saw two people at the check in counter and no one sitting in there waiting area. I signed in and waited 15 minutes for the desk staff to check me in but 7 other patients walked in and were able to check in before anyone moved to check the clipboard. I said back in line and they rudely asked me to sign in and I told them I did ahead and my appointment was in 5 minutes so I'd prefer to be checked in. Horrible service.
February 25, 2021
I love Doctor Mahmood! I'm so happy I stumbled upon her. She is very thorough and explains everything in terms you can understand.
February 25, 2021
This provider is amazing, I love how thorough and caring Dr. Mahmood is. However, calling the front desk to schedule or make modifications to your appointment is nearly impossible. I've called numerous times and the wait time is always more than 20 minutes for someone to answer your call. In my opinion, this is unacceptable.
February 24, 2021
Dr. Mahmood is a wonderful doctor. Very caring and thorough. I feel confident in her advice and recommendations. I highly recommend her to anyone.
February 24, 2021
She's very good and reassuring and you will feel that you're in the right hands. I would recommend her.
February 24, 2021
Always very clear in explanations of lab results. Explains whenchangingmeds or deleting meds. Takes lots of time to clarify questions/concerns.
February 19, 2021
Dr Mahmood is always very patient and goes through my medical history each time i am there. Makes changes that are needed and suggestions. She makes me feel comfortable and i trust her. Thank you Dr Mahmood
February 16, 2021
Dr. Mahmood, She is the best!
February 11, 2021
Had a video appointment for 8:40. Didn't speak with the doctor until after 9:00.
February 10, 2021
Very good doctor
February 10, 2021
I found Dr. Ghasak to be very on-point with her discovery questions in assessing my condition. She was knowledgeable with current treatments and initial dosages. I have full confidence in her ability to improve my condition.
February 10, 2021
Great doctor and her stuff. Treat me like their family member. I feel very supported and safe having such a knowledgeable doctor to count on any time when needed her assistance. Thank you ????
February 08, 2021
I love coming to this provider. She is a great doctor.
February 08, 2021
Dr. Mahmood has literally saved me from becoming an out of control diabetic. My A1C was 14+ when I first saw her. It is currently 6.6 and working on getting it lower. We've reduced my insulin and removed one from my meds. She is knowledgeable, explains everything that I need to do to get better. She is patient with me and takes all my other diagnoses into consideration.
February 04, 2021
Very happy with my doctor and staff.
January 26, 2021
I like to start by saying that I'm very happy with Dr. Mahmood in the few times that I've seen her since she was assigned to me. Unfortunately, I don't see her enough. I was turned over to see an assistant and I have very brief encounters with Dr. Mahmood. I saw her recently because I personally requested she's very hard to to get appointments with but she's a wonderful doctor. I am happy with her. I just wish there was more possibilities of meeting up with her as in a timely manner. Thank you.
January 22, 2021
She didn't seem to be quite interested in what I was saying. Just because I think I've got a very rare condition, and I'm not sure that she understood it. I will be seeing her again. She did order some tests to see where we were going. So I was appreciate of that. Thank you.
January 20, 2021
I switched doctor's because I didn't feel comfortable with my previous one Dr Mahmood is very professional thank you.
January 14, 2021
Dr Mahmood is always very kind, caring, informative and definitely treats her patients as though they are family. Very pleased with Dr Mahmood!
January 14, 2021
Dr. had a critical patient so that's why I had to wait so long and she was rushed. This is not the normal situation. I trust her completely with my care and I feel she listens to me. She knows me better than my primary doctor. I highly recommend her To manage my diabetes and thyroid condition as well as all my labs.
January 11, 2021
Easy and convenient
December 17, 2020
She's honest & gets straight to the point, says what you need to hear, because she wants your health to get better.
December 02, 2020

I would like to highly recommend the caring and efficient work provided by my doctor and facility.
November 16, 2020
She has the best approach, confident and knowledgeable is what she is! Her energy was everything! I went in afraid and hopeless and I came out of there confident and hopeful about the future.
November 10, 2020
Dr. Mahmood is very approachable. Best "bedside" manner.
