Dr. Kellogg has worked with me and my other Drs. for the last 4+ years to help me manage my chronic asthma. He has been easy to work with, clear in his explanations of the treatments he prescribes for me, and responsive to my needs. Highly recommend.

Dr. Kellogg spends a fair amount of time with me during my visits. I never feel rushed. He is kind, friendly, professional, and knowledgeable. I highly recommend him if you have allergies, asthma, or COPD.

Dr. Nelson has been very kind, patient, and extremely helpful with my infant son, and educating me, the parent. It is rare to find doctors this invested in patient care and outcomes. 100% recommend her.

Love Dr. Nelson! She is to the point, realistic and takes wonderful care of my little allergy sufferer. I'd recommend her to any parent with a child having allergy symptoms.

Dr. Zhang was friendly and really cared for how I was doing. She also really makes an effort to minimize cost for me as I am an out of pocket patient. Thanks!

Dr. Xu is a very patient and communicative allergist. She explains everything in detail and offers many treatment plans and has alleviated our allergies.

Dr. Katharine Nelson and the team are a treat to work with. From the moment we called to the treatment options and explanation of care they did a stellar job!

Dr. Kellogg is brilliant and the first doctor ever to get my symptoms totally under control and then most importantly to pinpoint the cause, explain it thoroughly!



You cannot find a better allergist than Dr. Zhang. She follows up with her patients and is very thorough!
