Dr. Li chose to go into medicine because she wanted to apply the knowledge she received in medical school to help and educate people in need of medical attention. “I enjoy both the challenges and rewards of patient care,” she explains. “It’s a privilege to be a physician and to participate in people’s lives.” In her spare time, Dr. Li likes to travel, hike and participate in outdoor activities. She enjoys sampling food from different cultures.

July 29, 2020
This was my first time seeing Dr. Li. She was very empathetic and listened to my list of issues. Given it was her first time meeting me, she was not quick to dismiss anything I said and I felt that she took my concerns seriously. She also seemed very knowledgeable and was very friendly and showed concerns for my discomfort.

I called for an appointment, scheduled a video conference, met with my doctor, and received a prescription all within a 3 hour window. The care was so immediate and the entire staff was very compassionate to my situation. Thank you so much.

I liked her! ;)
June 23, 2020
I shared with family that from the start of the appointment I felt ignored. The nurse who called me said nothing, nothing at all. No "hello" how are you... she pointed to the scale and then to the chair I was to sit in. Literally said nothing until I asked her how she was.
June 19, 2020
I am deeply impressed with PIH in general and Dr. Li specifically. Healthcare in this country can be chaotic and frustrating, so I count myself and my family as lucky to be cared for by you.

Dr. Li. Is a very kind and caring doctor. I trust her to take good care of me.
April 01, 2020
I called my doctor on the verge of a nervous breakdown. My anxiety has been much much worse the last few weeks and with no real end in sight I needed to let her know how I was feeling and that I may need additional help or to switch my medication. She listened to everything I said as I mostly cried the entire call. I am grateful she took the time to talk to me and let me know I wasn't alone.
March 30, 2020

Dr Cathleen Li was very polite, spoke very softly and actually took the time to listen to me. Not in a hurry like some other PIH physicians that irk me.

Very pleased with the professionalism of the doctors and staff at this location. Was a very pleasant experience.
October 15, 2019
The doctors, nurses, and physicians assistants at PIH are wonderful. However, it's very difficult to get an appointment (I always need to call 3 weeks in advance) and the call center system does not properly update patient information.
October 15, 2019
I like my provider.
