What Our Patients Say

Just recently diagnosed with A thyroid condition and I was nervous and didn’t know what to expect, but the doctor was great and very knowledgeable and the staff was top notch! Overall great experience!

Inland Endocrine Patient

Dr. Tahir Haytoglu took the time to listen and explain everything-the condition, treatment, options, and why etc. It is a luxury for a physician these days to invest some time in their patients and that is very much appreciated. This is what health care is all about.

Inland Endocrine Patient

Dr. Heather Heck was amazing. I was hesitant because I’d never seen her before. She was patient, thorough, easy to understand, and didn’t seem to mind answering my questions. Look forward to seeing her again. The staff was very friendly.
