I have called this office 4 times. In addition, I have also attempted to schedule online. My wife also tried calling and making an appointment. This office is incredibly and lacks the human decency to call back and schedule an appointment for someone in need.

Our son has been driving from Houston to see Dr. Martinez. Today I saw why. He and his staff are the most kind, compassionate and dedicated medical professionals I have ever seen. He and his staff moved mountains to make sure the proper tests were performed for a diagnosis. I’ve worked in health care 30 years and NEVER seen any Dr’s or nurses that take such extraordinary care and efforts for a patient!

Dr Nicholas Martinez is my daughter’s gastro dr and the best she’s ever had! He’s knowledgeable, kind and compassionate. He takes his time with his patients, listens to their concerns and does his best to help them in any way possible. I highly recommend him. Unfortunately this office will no longer be taking our insurance and it will be impossible to find another Dr as good as him.

Dr. Martinez is the gold standard of what an every physician should be. He took the time to listen to my concerns and created a specific care plan for my medical needs. Every individual that I encountered this office was extremely caring and professional.

Dr. Martinez is one of the best doctors I’ve ever had! He is so personable and cares deeply for patients. He recently helped me resolve a serious health situation that almost landed me in the hospital. I recommend him to all my family and friends! I’m so thankful to have found such a qualified, caring doctor.

His nurse Amanda works so hard cares for every patient goes out of the way to get things done for Dr Martinez The staff works hard and they are very attentive as well with great communication thank you Dr Martinez and staff .

I would love to have a job like Myriam the scheduler. It seems she is never doing anything since even after calling 9 times in a day, she is always away from her desk. The one time I do get to speak with her, I'm placed on hold and the call is magically dropped. On top of that they give us a schedule for 1 week out and then magically change it to 1 month out. I guess my family member can hold her pain for an extra thirty days. Thanks, Myriam.

Takes the time to listen to ,y wife's health issues and explains the issues with such patience. She doesn't feel rushed with him like she has in the past with other doctors. Also his nurse is awesome.
