Friendly and thorough

Very attentive, professional and friendly!

Was 35 minutes late and then rushed me. Did not refer to any of the notes from past visits; I felt like a number, not a person. I waited a month for this appt only to be told I needed to make another appt for other issues I had been waiting to talk about, after only seeing him for 5 minutes. Terrible experience, left feeling totally defeated and angry at our joke of a medical system.

Dr Casas is excellent he listens and without rushing one out.

Thorough...and up front. Honest...and he LISTENS!!!!

In appointments, he will cut you off and not answer questions you have because he says you arrived late and ends the appointment. Changing doctors because of this reason. There have been numerous times when I arrive early to my appointments but end up waiting an hour to actually see the doctor without complaining about it.

Excellent Doctor, great service and very efficient.

Dr. Casas is considerate and listens to what I’m saying and feeling

I find Dr. Cassis very personable and extraordinarily patient in hearing my opinion. While none of us have all the answers, he is forthcoming in letting me know when he doesn’t have an answer. He outlines how he’s going to investigate ways to find the answers and assures me he will be back in touch when he has additional information. I find his bedside manner quite refreshing.

Even it was an appointment through phone,he sounds that he knew the causing of my illness and took care of it The only problem is my prescription got stuck somewhere in the system ,was done electronically and had a hard time Trying to get the medication with the pharmacy a, don’t know if is WI-FI issue but the next time I would like to get a hard copy of the prescription

Phenomenal bedside manner, professional, knowledgeable, attentive, caring, and the staff as well in a clean serene environment. We thank you all.

The nurses in the Home where I lived made this appt. for me. I did not know Dr. Casas was a man until I met him. For PCP, I require all Drs to be female. This is the nurses' fault, not Dr. Casas'. I need a new, FEMALE physician.
