Hillard Zallen MD | Kaiser Permanente

I've been a patient of Dr. Zallen's for a few years. He's always been very approachable, direct, and knowledgeable. I'm happy to have him as my primary care doc.

I've been a patient of Dr. Zallen's for several years now, and I've found him to be knowledgeable, understanding, and helpful. He's listened to me during my appointments, and is interested in helping address any issues or concerns I may have. He's direct, and perhaps that's not what some patients want in a doctor. I, however, appreciate that he's going to presnet me with the facts, and advise me on how to proceed in an honest and helpful way. I also appreciate that he's willing (and in fact, often recommends) contacting him via email or phone before making an appointment when possible, as emails & phone calls don't incur any out of pocket expenses on my part.

Amazing Doctor. I had seen probably ten doctors by the time I had met Dr. Zallen. I had been having horrible stomach pains for months and was unable to get much of a diagnosis. I was just taking an over the counter medicine everyday and wasn't really healing. On my first visit with Dr. Zallen, he ordered tests that gave me complete peace of mind and had me on the road to recovery the next week. I have since felt better and returned to a normal life. I think very highly of Dr. Zallen, he is very knowledgeable and I am both grateful and impressed at what he did that others could not.
