I came to Dr. Jen with my diabetes out of control. He carefully and systematically worked with me to bring my blood sugar (A1c) to normal in 1 year! I tell you he is wonderful, patient and kind but mostly very knowledgeable. If you want the best doctor - it's Dr. WenCheng Jen! Carmen M.

Both my parents are now switched to Dr Jen as their primary care doctor. It is such a wonderful experience, minimal waiting, great office staff and Dr Jen is patient, knowledgeable and spend time to understand his patients, we don’t feel rush at all. It is a day and night contrast from my parents previous doctor. Thank You to the reviewers and that was how we found Dr. Jen. This is my first time ever writing a review for a doctor. Dr Jen is great.


Dear Prospective Patients,

I am Dr. WenCheng Jen. I would like to take care of you and your family. I will be glad to be your primary care doctor to lead you to a healthier future.

My parents brought me and my siblings from Taiwan to the US when I was a toddler. Our humble beginnings started in LA, then in Alhambra. I attended Ramona Elementary School through Alhambra High School. I went to UC Berkeley for my bachelor's degree then returned to USC Keck Medical School, where I gained much local experience around east LA. I finished residency at UCLA-Olive View Medical Center in Sylmar. I dedicated more than 15 years caring for thousands of patients and their families in the San Fernando Valley at Facey Medical Group in Mission Hills.

I wish to extend my care to you and your family. My staff and I want you to feel comfortable and confident in our care. We want you to easily get answers to your concerns and questions. We speak Spanish, Mandarin and Cantonese.
My staff and I want to thank you to allow us to be part of your home community and your future!
