I would not recommend this doctor to female breast cancer patients at all. He doesn’t care about them.

Dr Marek listens. He is approachable. Of course he is well qualified to answer most of your questions. So very thankful to be one of his patients.

I have had Dr. Marek as my doctor for over 20 years. I think he is excellent. He has allowed me to be an active member of the team treating my disease. He has provided me articles to read and taught me my options. II am impressed by his professionalism and expertise. I highly recommend him. I also really like his staff. They are efficient and personal.

Yes, I do recommend Dr. Marek to my family and friends. He saved my life and I trust him to continue to save it. He is always friendly and professional when I have an appointment with him. He is very efficient and takes the time to answer any questions I might have without trying to hurry me up.

My experience with Dr. Mareck and his staff have been awesome. They all are very helpful and friendly. He has taken care of my mom’s and sisters cancer treatments. He impressed me with his to the point attitude and directness.

Appointment was on time and service was very professional. Nurse that attended me was very knowledgeable about infusion being administered.

Wonderful understanding doctor. Takes time to explain results of all testing. I am moving north and will surely miss him and America. Two great medical people

My visit with Dr Marek was excellent. He is a very nice doctor. He has been my Dr for about seventeen years.

Everyone is very friendly, Dr Marek is always very pleasant, and makes me feel comfortable.

Dr. Marek is a very knowledgeable, up to date Dr. He is both friendly AND professional. I find him to be vey straightforward and caring. Have been his patient for 20 yrs. with complete trust. His waiting time is minimal, good staff.

At every check-up, Dr. Marek shows great concern for my condition and the way I feel. He goes over and beyond asking me questions about how I feel, checking my blood results, and thoroughly discussing them with me.

Dr. Marek and the staff at Texas Oncology in McAllen were terrific. Everyone was always very nice and friendly. My husband and I were scared when we learned I had breast cancer but after going to M.D. Anderson for a second opinion, I had previously gone to DHR and felt very ambivalent about getting treatment there, someone recommended Dr. Marek, when we met with Dr. Marek we both felt relieved and knew we had made the right decision. Which we did. Our visits with Dr. Marek and the treatment team all went very smoothly. They are all professionals.

Dr. Marek is great. Best run office I have ever been to

I always have a good experience with Dr. Marek. I hope it would never be needed, but if it were, I would most definitely recommend him to others.

Very good appointment with Dr Marek would recommend the doctor.

Dr Marek was highly recommended and exceeded my expectations in a physician. He is very knowledgeable and answers all my questions thoroughly. I'm very pleased with the care I've received. I'm a 2 year breast cancer survivor.

Exceptional Care and concern about the patient not a number, but a person. Excellent communicator and guide through trying times. A man who one wants to call friend.
