Special Interests

Clinical Interests

Allergic rhinitis and Allergic Asthma
Allergy Immunotherapy (subcutaneous allergy shots and sublingual therapy)
Primary Immune Deficiency

Research Interests  

My research focuses on the mechanism of immune tolerance, specifically how the immune system works and controlled, what aberrations occur that cause allergic diseases, and how those can be modified. I am particularly interested why/how children develop allergic rhinitis and allergic asthma and in defining molecular biomarkers that predict the effectiveness of allergy immunotherapy.

Patient Ratings

The Patient Rating score is an average of all responses to care provider related questions on our independent rating system, the Press Ganey Patient Satisfaction Survey. This survey is about the patient care experience and does not address crucial characteristics like medical decision-making, prescribing the best therapy, and patient outcomes.

Responses are measured on a scale of 1 to 5, with 5 being the best score. Learn more about our patient satisfaction survey.


Comments are collected in our Press Ganey Patient Satisfaction Surveys. Patients are de-identified to protect confidentiality and patient privacy. Learn more about our patient satisfaction survey.

*Dr. Chan spoke to us in a very condescending manner, as if I was a complete idiot and didn't understand my son's condition. I would not want to see him again. However, the fellow (resident) that met with us prior to *Dr. Chen was excellent.

National Jewish Health PatientDecember, 2018
Dr. Chan is the best. he resolved and awsnered so many questions we have had over the years.

National Jewish Health PatientJuly, 2018
I have an advanced degree in health care and consider myself well-informed and this provider was very difficult to follow and understand. I had to ask him repeatedly to explain it differently for both me and my son to understand.

National Jewish Health PatientApril, 2018
Dr. Chan is always friendly and takes his time. My biggest concern is that he isn't always a good listener and he sometimes doesn't pick up on emotional cues from his patients. For the last couple of times he has chosen to talk to my son about his weight. He didn't bother to ask if we'd talked to our pediatrician about it (who says my son continues to grow on the same trajectory he has been on since infancy), he didn't pick up on the fact that there was discomfort about the conversation, [PHI]. He made assumptions about our family's activity level and food consumption and it was insulting.

National Jewish Health PatientAugust, 2017
Very good and I hope all the hospital be like this care.

National Jewish Health PatientJuly, 2017
