Really nice doctor. He took the time to explain to me...what I needed, and he's been my doctor for years, and I would recommend him to family and friends. I thank him for his...friendship, as well as his knowledge.

Much better than (name removed). So happy I found Dr Castellanos. I don't think (name removed) did everything AND most importantly, waited so long to try something. Hopefully I can make a full recovery.

The doctor has great bedside manners. Very informative and definitely a professional. He explained everything and didn't rush off to the next patient.

They take too long to schedule an appointment to see the doctor usually 2 months that's unacceptable doctors don't get familiar with your health history and don't read patient notes

Dr. Alfredo Castellanos took the time to listen to my health concerns and patiently answered all my questions. (NOT once during my Dr. visit did I feel like he was rushing me through the process.)

Dr Castellanos was very concerned with my situation and recommended new examinations. I'm very pleased having him as my new doctor specialist in pulmonary issues.

No, the visit went very well. The doctors were extremely nice, and so was the staff. Everything was perfect. I couldn't answer any more. Bye.
