I had an urgent medical need on a Friday. My normal provider was off on that day. The MA team saw my note I had sent and quickly called me to get more information. They took this information and Spoke with Dr. Castillo who graciously said she we see me. I had a very painful and worsening [diagnosis]. Dr. Castillo and her MA took amazing care in explaining what was happening and that she thought it best to [service]. Because I am on [service], Dr. Castillo was very concerned about me going into the weekend and having any bleeding problems or concerns. She gave me her number if I had any problems. I so appreciate Dr. Castillo stepping in to help with my care. She put me at ease and was so compassionate. Thank you Dr. Castillo and thank you to your MA Whom I cannot remember her name.

March 21, 2022
This provider and her staff is so kind, courtesy and profedsional that words cant describe
March 18, 2022
Sherry is very competent, but at the same time grounded, humble, I am not sure the exact word. Dr Castillo is the epitome of what an internal med doctor should be. She is able to multitask and make sure an [diagnosis] in room #2 gets shunted over to the appropriate specialist within minutes all the while [services] for a pathologist in Room #3. She does it all with "I get it" clarity!
March 17, 2022
Oh yes. You see there happens to be this wonderful person named Taylor. She always goes above and beyond with her treatment of members of our family. Let me explain, Dr. Castillo is amazing and spends an awesome amount of time with her patients, and sometimes that means that she's running behind, but that's totally fine with me, because like Heinz ketchup, some things are worth the wait. (Yes I eat french fries, and yes that's why I'm fat, no I don't want a diabetes test yet...) N-E-Way, so there I was sitting and waiting for Dr. Castillo, and Taylor was like, "yo, I will put my just put my things aside and calm this patient and stay on the phone with him because he'll probably hang up and go eat ice cream if I don't" so she talked to me, and I could here her typing and verifying things and obviously that's a miracle, because who really can honestly multi-task...yeah! NOT MANY PEOPLE, but Taylor can. She's amazing! You're so lucky to have her. Woot!

Dr. Castillo, her initial nurse ( don't recall her name), and April who called with test results, were outstanding.

I want to give recognition to the following, Lori Morgan, Kathy, Sherry Castillo. I have been a patient of Lori's for years. Because of the Medicare changes, I was assigned to Sherry. I met with Kathy who did intake and she was thorough and very professional. When I met Sherry, it was as though she had been my doctor all along. She listened, gave helpful input and above all she treated me not only as a patient, but a friend. She made me feel very comfortable and that what I had to say was important in helping her diagnose my health issues. I will miss having Lori as my PC, but I feel in very good hands with Sherry.
