Dr. Castro is an excellent doctor! I wouldn't want to be under the care of any other doctor in his field. He listens and provides the correct treatment of care for my individual needs which is unlike my past experiences with other providers. Very polite, professional, and shares his concerns and care. Top tier doctor in my opinion.

Dr Castro is by far the most concerned, engaged, and genuinely caring physician I have encountered in many years. During my current long term bout with cryptogenic organized pneumonia he has been a beacon in his sensible approach in dealing with my illness. I will be ever grateful to him for helping me overcome this illness.
