She was 45 minutes late and she didn’t have too much time for me. She didn’t even have time to go over my chart and ask me about my medications. She spent about 5 minutes with me. I want to get another Dr. If I can. One that will spend a little more time with me. This Dr. Is always running late. That’s why I make appointments for a certain time of the day. I have other things to do then sit and wait for her.

Dr Del Portillo is caring, knowledgeable, thorough, and kind. I'm very grateful to have her as my PCP. (She's also funny and makes me laugh.)
