"I chose to be treated by Dr. Castillo as he is also named Castillo. I was incredibly impressed with his bedside manner and empathy for my diagnosis and my trepidation in having to have surgery on my face. He explained every detail of the surgery, made sure I felt no pain, and even allowed me to choose the music which played during my procedure. My skin is now healed and I am BERY happy with the result. I had a large cancer and my nose looks better than it ever has without a scar to be seen. All I really cared about was getting rid of the cancer and looking better was just a bonus. I HIGHLY recommend Dr. Jason Castillo."

Data Transparency and Trust: Understanding WebMD Doctor Listings and Reviews

We know that finding the right doctor or provider is important to your health. That’s why we want to ensure you have confidence in the provider profiles and listings you see on WebMD Care. Our provider data is sourced from the physicians themselves as well as publicly available databases. Any doctor or provider who claims their profile by verifying themselves can update their information and provide additional data on their specialties, education, accepted insurances, conditions they treat, and procedures they perform.

All the physician and provider reviews on WebMD Care are provided by users just like you. Knowing these reviews provide insight into how other patients feel about a doctor, we maintain internal policies and protocols to ensure the quality and accuracy of all reviews. Providers are not able to remove or modify reviews on their own. Reviews can only be removed after an internal review by our customer service team.

We value your input and encourage you to reach out to our support team if you encounter any issues.
