An excellent first visit to this clinic, I must say. All departments offered warm introductions, courteous interaction and professions care. The clinic was well staffed, well equipped and showed like new cleanliness. My doctor explained my condition in understandable detail, asked relevant questions and performed procedures with step-by-step detailed explanation. I felt she new her job but most of all really cared about my well-being. This seems to be a nice clinic to be treated in and has good, warm-hearted professionals tending to the services. I like the Endocrine Center.

Dr. Ortiz was so very informative and professional. She explained everything to me in a very clear manner. She explained the difference between a normal and abnormal thyroid using actually ultrasound images before she did my own ultrasound. I would highly recommend her. Thank God for Dr. Ortiz!

Dr Cantu is amazing. She takes time to talk to you during your appointment and is thorough when reviewing your information as well as providing it. Portal allows for communication if needed between visits. Also was able to squeeze in an appointment when I wasn't feeling well without having to wait a million years.

Dr. Gloria Ortiz is professional , organize , competent and very nice! She wanted to have her own opinion about my case before reading up my history with other doctors, thats how confident she is own herself! I am going to start a treatment with her to recover hair loss over a thyroid medication that Ive been taken in a wrong way. I cant wait to start!
