Dr. Castaenda takes the time to explain any question or situation I may ask about. She cares very much for her patients. i feel very comfortable with her. I trust her to tell me what I need to do for better health.

Me gusta la Dra. Castaneda, es muy linda.

I came in scared and fearful. Had been sick since Aug. 2018 and was being tested for everything and they found an issue with my thyroid and visible nodules. They did a biopsy negative for cancer but they recommended surgery. After last labs they found my thyroid 100% healthy and I was in shock to think they would of damaged me for life. Was referred by the surgeons patient with Dr, Haydar best decision ever. Once he gave me the np thyroid my life changed. Very grateful and I feel great!

he is an excellent person, I feel comfortable and in very good hands every time I visit.

Laura was very Caring, very good listening skills, wonderful job and so was Miranda Castaneda

My experience was very good. My wait time was short and my procedures were very thorough. I highly recommend.

El Dr. Haydar es siempre muy profecional, sus diagnosticos certeros y deja al paciente tranquilo con su clara explicacion.

I have been seeing Dr. Haydar and his clinic, for several years now, and have had excellent feedback on my way to a healthier life. They have gone deeper and been able to resolve my new age issues also. I don't have any complaints. They are very well prepared and are always on top of my lab results. I am very happy with the girls handling the front office also. They are always very nice and willing to assist when necessary.

Dr Haydar is by far the best provider I have found in the border town. After years of struggling with female hormonal imbalances at an early age, he carefully listened to my symptoms and addressed the problem from the root. Most doctors prescribe conventional medication only, but Dr Haydar addresses all aspects of life so that patients get back to a healthier path.

Very professional is the best Dr i have ever had and i have had an excellent experience he listened to my problems and he really cares about my concerns

My visits always go well with Dr. Haydar. He is a very good Doctor.

The few times that I have seen the doctor, I greatly appreciate the time he spends and dedicates to me. He explains everything to me very well. Over all his dedication is excellent and always focuses on my health and what I should do to keep myself healthy.

Patient feels good with Dr. he is precise on what he is saying, she has been here 20 years ago and she had been receiving a good health service.

Dr Haydar us an excellent Dr i would recommend him to everyone he was very attentive and was always following up with me when i was in the hospital.

I have worked in the medical field for years. Around many physicians and I feel he is the best in his field. He keeps up with all the current medical updates and never stops educating himself. He goes above and beyond to find the problem and does everything he can to fix it.

Dr Haydar has been my Dr for more than 5 yrs

The wait is a bit long but it is worth it. I feel a log better since I started seen him for thyroid problems.
