Very thorough exam and history taken. Professional and personable doctor. Clearly explained conditions, issues and his opinion. Excellent follow-up and friendly nurses/staff.

I need assistance in changing my diabetes medications due to high sugar levels. I was looking for assistance regarding new oral meds that would help with insulin resistance. The answer I got was increase the amount of insulin. I am already taking an unusual amount of insulin daily and needed different help such as combining oral meds. I would never recommend this doctor.

I made an appointment with Dr Orrego due to the constant pain on my thyroid nodules. Not only Dr Orrego said he had no idea what caused the pain, he expressed that i was over-worried about it. Did i hear it right? Seriously? Of course i was worried. He did not offer ultrasound, x-ray, or any kind of examinations. All he offered was to have the nodules removed. A surgery! He even insisted that it is not and will not be cancer due to the fact that the FNA peformed 2 years ago showed it was not.
