He is very bright and quite perceptive, a good listener and explains findings and future plans. I have seen an endocrinologist for 20 years w/o ever having a full work-up done to address some bothersome adrenal issues. I have hope for some solutions now because Dr. Barrera is so thorough. I also value his interaction with my cardiologist!
