Dr. Gerald Muthu MD of Casa Grande, AZ is my personal doctor for around 18 years. He is an excellent doctor and his staff gives me great service. I will be sending him my records from my summer home in Iowa and I will be seeing him on Oct. 21 at 9:30 AM and he will give me all the answers I need.

Horrible front office personnel. Mrs. Muthu, who runs the office, has a mean and nasty disposition. "Do no harm" is the last thing on their mind. They did me terrible emotional harm.

Excellent. He is the only doctor who found my tumor and aggressively chose the path for me that saved my vision and my life! I am forever grateful to him. Also, the front office staff is friendly and so helpful. There have been a few times I am waiting past my appointment time. I know that this time lapse is because Dr. Muthu is carefully attending to a patient just as he does every time he see's me. My Uncle once told me that "a good patient has to have patience."

We had to change insurance to the Marketplace and needed to change doctors. After asking friends and CG Chat (I know) we chose Dr Muthu since everyone seemed to be pleased with him. The staff was courteous but business oriented which kept things on time. Dr. Muthu was friendly, pulled up records quickly from recent tests, and gave an overview of a plan of care. Referrals and prescriptions were done within 48 hours. I will update this review after my next appointment but I am pleased with the care.

I am a Type-1 diabetic, and Dr. Muthu has been my physician for about 25 years. He is the finest and most caring doctor whom I have ever known. He always patiently listens and cheerfully responds to my sometimes numerous questions and concerns. In addition, Dr. Hudak, Mrs. Muthu, and the nursing and front office staff are outstanding.

Dr. Muthu has been my & my husband's physician for 4 years since I moved to Casa Grande in 2015. He's personable, easy to talk to and listens to what I have to say. Over the years I've had minor health issues that he competently addressed. The other issue required a referral and he was not hesitant to refer me when necessary. For regular health monitoring and age-related care he's been great.I've never had a bad experience in his office and find his staff courteous and helpful. I've referred friends to him and they've been very happy with his practice.

My husband had a "new patient" appointment. Dr. Muthu actually read all of the paper work we filled out. He asked smart questions. He was knowledgeable regarding my husband's health issues. He spent enough time with us to access my husband's health needs. We feel blessed to have connected with this professional.

Was on hold 11 minutes just to be disconnected, no apologies, just an attitude, 'if that's a problem , maybe we aren't the dr for you.' Absolutely. Never will recommend due to front office attitude.

I like Dr. Muthu very much, but his wife runs him and his staff. I am in Colorado for the summer in our RV to visit family. I needed my prescription refilled, and Mrs. Muthu said I would have to come in. I explained to her that I wouldn't be back to Arizona till October (it's August now). Too bad, you have to come in she said. I have never had an office treat me so horribly, or a doctor that I couldn't talk to. I really need my medication - it is life threatening!

very caring and compassionate doctor I have been to nearly all the others in town and have finally found this doctor who actually cares and is very very well read in all areas of medicine. Its disturbing to see comments from people who mention old staff etc etc and about the doctor. I would recommend him highly. He takes of a lot of my other family members as well.

I had two appointments with Dr Muthu, and both appointments, I waited 2 hours to be seen. At one point his staff asked me, so I commented about this - I said, I really like the doctor, but the wait is too long - I work. Then I had to cancel an appointment. When I returned to the office for a scheduled appt, the staff actually seemed to take great pleasure in firing me (loudly) from their practice in front of a waiting room of at least 10 people. I had to ask for my $250 deposit back after
