Corey J Lum, DO

Dr. Corey J. Lum is a caring and thorough specialist. He is kind and puts you at ease with his smile and warm greeting. I am extremely grateful to be one of his patients.

I was very pleased with staff and doctor at the La Canada location. I was very pleased that doctor Lum would see me as a second opinion doctor even though my issues were far less complex than the patients he normally works with. He was able to assure me that my doctor is planning the exact same procedure, meds, and tests that he would recommend. He also talked about some issues that I haven't talked with my doctor about yet and need to be discussed. This took to a big load off my mind and I grateful that Dr Lum would see me. I was not pleased with the gatekeepers that answer the phone when you call Intermountain. I had many phone calls to them to arrange to see a cardiologist. Never once did I get any satisfactory answers!

I'm so happy to be able to see Dr Lum...I feel very comfortable with him and I believe he knows his stuff....thank you on 12/17/25 had a visit with Dr Lum ...usually he is very patient and kind, however that day I felt very rushed from the appt....I sometimes have trouble finding my words when asked a question and he wasn't giving me time to express myself...I didn't like feeling like I wasn't important as a patient.

Excellent Doctor! Actually takes the time to answer and explain all of my questions. I would highly recommend him if you're looking for a great doctor.

Dr. Lum always clears up my concerns with the right information. I feel more comfortable after my visit with him. His staff takes very good care of me and answers my questions when I call.
