Do not come here if you need intermittent fmla......such a stressful experience....
in Las Vegas, NV |
I have never had a bad experience with Dr. Ma or her office. I would recommend her to anyone that needs a GI doctor. Her staff has always been nice and helpful. Dr. Ma takes the time to go over all results and does not rush your appointment, she takes the time that is needed....
Las Vegas, NV |
I have been a patient of Dr. Ma's for 10 years. She has shown herself to be a thorough, knowledgeable and caring doctor. She is able to explain her diagnosis in understandable terms; and she has been willing to take the necessary time to answer my questions, both pre and post-op.

I would never recommend this doctor. Not only is her beside manner questionable but her staff is horrible. When you aren't feeling good, you are looking for an office that lends support, not one that badgers you. This is definitely not the place to go if you are looking for help.

Please beware if you're making you 1st appt. Their staff takes all the insurance information but will not tell you if they accept it or not until you are done with 1st appointment and in process of scheduling your followup. This is when they tell you that they don't accept your insurance but you have to pay for your visit. Now you have to look for another Dr. and go through the same process. What upsets me is they don't really care if they wasted your time long as they get paid.

My husband called to schedule an appointment and a very rude receptionist Karen answered the phone. She rushed him off the phone and hung up on him when he was asking questions regarding a potential appointment. I then called back and proceeded to ask questions, she gave answers that made no sense and could not explain thoroughly the doctors policy regarding the acceptance of new patients. Karen needs to re-evaluate her attitude and demeanor on the phone as it is a reflection of the doctor.

Dr. Ma is great and I felt very comfortable with her. I agree with other reviewers - her staff do not seem to be interested in helping you. I can't decide it if just because they are you and most likely inexperienced or need better training or really don't care. It could definitely be a detriment to Dr. Ma's practice.

I would never recommend this doctor, they will not see you as a patient if you have ever seen another Gasto doctor. According to Jessica in the office, this is their policy and if we wanted to see Dr Ma then we should have contacted her first. I asked to speak to the office manager and she had just left and I was not allowed to leave a message. The office staff was very rude and they could care less about a patient with an issue.. This was very disappointing, doctors are suppose to care...

Did not have a chance to meet Dr. Ma. I was just calling in for a colonoscopy consultation earlier this month and the staff that answered my call is such a rude person to talk to. That is why I ended up looking for another doctor.
in Las Vegas, NV |
Dr. Ma is wonderful at listening and explaining her plan of treatment. I have had 2 colonoscopies and 3 endoscopies performed by Dr. Ma. She was wonderful, kind, and caring.
in Las Vegas, NV |
Dr. Ma was the physician I used for my colonoscopy. From start to finish, it was smooth sailing. Dr. Ma is very professional and knowledgeable. The procedure was done at Southern Hills Hospital. Very short wait time from when I got there until I had the colonoscopy done. Hospital staff was very friendly as well.
