My visit with Dr. Marshall was less than satisfactory. My wait time was over an hour. I had not seen Dr. Marshall in two years and after this visit felt like it was time for him to retire. His demeanor was dismissive and condescending. His suggestions for my concerns were to get a gun, and walk my dog in the desert like he does after a 10 hour day. Oh yes, and to take a baby aspire. He spent more time on what type of gun I should buy than on my health concerns.

I saw Dr. Marshall foe about 10 years and he told me that I have no hearth condition. He said that I have a valve leak, but it is so small that does not need any intervention. He watched it all this time, took tests every 6 months, and the answers were all the same. When I could'n't walk 10 feet without stopping to catch my breath, I went to another Dr. just to discover that I was dying. I had immediate surgery, and I am OK now, but I lost a lot. Do yourself a favor ans have a second opinion.

Saw Dr Marshal numerous times from 2001-2002. Had three stents placed and folks I am still here. He is the best along with Dr Singh, Dr Taussig, and Dr Ruben original Docs and Dr Jorge Saucedo who place the last two stents in Oklahoma. would recommend to anyone wanting excellent heart care

I'm a health care provider and I brought one of my patients to Dr Marshall's office today. Upon walking in the waiting room was full and the staff was overwhelmed. Top to things off the doctor let's his dog roam free in the clinic. I have severe dog allergies and started having problems breathing and my eyes begin to swell shut. I asked to have the dog moved to the back or for my patient and I to be. I was told that there were five other patients to be seen first. I ended up in ER!

My family had been with Dr. Marshal for over 20 years. My parents were his patients first and then I in 1997. When he attended to my parents and myself he was amazing. Compassionate, caring and very competent. In recent years he has changed. Probably he has spread himself too thin. At my last appointments I found him to be harsh, uncaring and cold. He seemed overwhelmed. I have moved on to another cardiologist

My husband came to Dr. Marshall for a 2nd opinion and chose to stay with him . Dr. Marshall told my husband that the first cardiologist had misdiagnosed him . After almost one year with Dr. Marshall, he went to Mayo Clinic and has seen two cardiologists- a cardiac generalist and a cardiac interventionist. Both said Dr. Marshall's diagnosis was wrong. It turns out the initial cardiologist was correct. The interventionist said my husband's cardiac care, by Dr. Marshall, was poorly managed.

Dr. Marshall is personable, takes the time to explain any results or tests and is very good at what he does! The best cardiologist in Tucson. A nice guy and so great having dogs in the office! Great for calming down any nerves I have.

Dr M's patient since 1998. Find him caring, professional and easy to talk with. His staff has been excellent--since I have to drive from Sierra Vista would not see him if I did not have complete confidence in him. OT--the dogs are a nice touch!!

I am young, and I look healthy, but I am not. Dr. Marshall told me that I didn't have diseases that are outside his area of specialty, and the worst part is that he did not even ask me the established diagnostic questions to determine this. Dr. Marshall may suffice for you if you have a straightforward case, but if you are an unusual case, then you may leave the office feeling demoralized (and you'll pay $100 for it too). I don't trust that my cardiovascular system will be well assessed here.

Dr. Marshal and his tech were insensitive and unhelpful. The tech was uncaring and unknowledgeable and caused bruises. I would be happy to supply photos.
