I go to Dr. James Gallagher @ Associates in Birth & Gynecology ###-###-####. His office is in the Morton Plant Outpatient Center on the corner of Tampa Rd & McMullen Booth. I had a high risk and complicated pregnancy and he and his office staff were FANTASTIC. He is a single practitioner office, which I loved because then I knew for sure who would be there for my delivery and was comfortable that he was up to date on my care because he was always the doctor that did my visits. He is very dedicated to his patients, he saw me in the hospital many times after hours and on weekends (I was in the hospital multiple times prior to delivery). He has office hours until 7pm Mon-Thurs and has office hours occasionally on Saturday. I know of multiple people who have gone to both of the doctors/offices you mentioned. All of the people that I know have had bad experiences with Dr. Marks. I have a good friend who had a horrible experience with his office and actually switched to Dr. Gallagher and is very happy there. I don't know of anything specific on the other doctor, just that they are a multi-doctor clinic, which means that you may not always see the same person and whoever is on call will be there for your delivery, not necessarily the doctor that you have the relationship with. I did see a few other people recommend other places, I have personal experience with Dr. Zbella's office. He is very nice, but, I wish I could say the same about his staff. I went there for fertility treatments and would wait days for phone calls to be returned and had a lot of problem with their billing. After a little while I realized that they were all about the money and if you didn't know better, they seemed to trick you into paying for things. They got me to pay out of pocket for a number of things that my insurance also paid for. I had to request multiple refunds from them and threaten with a complaint to the insurance commissioner! Please let me know if I can be of any other assistance. I did have a c-section with Dr. Gallagher and he is a wonderful and maticulous surgeon, if that is something that you are concerned about! I know of a physician's assistant who has worked in the OR with him and says that he is a perfectionist when it comes to his surgery, one of the reasons I chose him!
