I had to go to Mercy Hospital, and specifically to Dr Diaz-Montes. She saved my life within a week. There was at least four doctors at my local Central PA Hospital who would not give me the life-saving surgery I needed. Not even when I was in the hospital begging for the surgery I needed. My body was shutting down and Dr Diaz-Montes saved me.

Dr.Teresa Diaz-Montes is hands down the best doctor I’ve ever had. She takes the time to explain what’s going on, your risks and what is quality of life to you. I can feel her compassion when she speaks to me. I’m a RN so I’ve been around many doctors over time, she truly is the best. I trust any suggestion she has when it comes to my care.

This is one of the best doctors ever. She got me through a very rough cancer scare and treatment at over age 60. I am fine now and greatly appreciate the skills, professionalism and personalness of this doctor.

If you have been diagnosed with a gynecologic cancer, Dr. Diaz-Montes is the person to see in Baltimore. I was very impressed by her knowledge, bed side manners and compassion. She kept me at ease during difficult times and help me navigate through the system.

Dr. Diaz Montes is a great doctor who fully explained my endometriosis. She is very knowledgable and kind :). I went through a surgery before her and they didn't accomplish anything and took three hours. Dr Diaz took my tumor out with salvaging everything and took an hour. Love her

I just want to say that you cannot find a better doctor than Dr. Diaz-Montes. She is very clear in her explanations, she has always seemed to have all the time I needed to talk to her, and her professionalism and caring are both top-notch. I am so glad I randomly chose her to be my oncologist.

If you have gynocological cancer, Johns Hopkins is where you want to be treated, and Dr. Diaz-Montes is the 'go-to' doc. I can't say enough positive things about JHH, the staff, and the doctors. And Dr. Montes is the best of the best, IMO. Seriously, she saved my life--thank you, JHH, Dr. Montes, and ALL the staff--you are the best.
