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!

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!

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!

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

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 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

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 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 ????

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.
