I cannot rave enough about Dr. Chan. It was obvious from our first encounter that she really cares about the patients and families she works with. She consistently went above and beyond for my family, making sure my son was getting the help and support he needed. She was also instrumental in getting my son into another specialist when we had difficulty doing so on our own. She is thorough, explains things in ways that are easy to understand, and knowledgeable. I would highly recommend Dr. Chan!!

Dr. Chan really cares about the patients. She also wants to make sure parents completely understand what is happening and they are facing. She was literally my son's life saver. I completely recommend DHAD.

Dr. Chan is FANTASTIC. She GENUINELY cares about her patients. I unfortunately have been seeing her frequently for over 6 months and she has never gave us anything but the best care. She addresses every concern thoroughly and does not rush our appointment no matter how busy she is. We have received phone calls outside of normal office hours (Ex: 7am or 7 pm) directly from her checking on an issue. Dr. Chan is also knowledgeable in her field and I trust her decisions completely. Thank you for taking such good care of my daughter and helping us through her medical needs.

We first encountered Dr. Chan when my Son was hospitalized at Children's, she is an EXCELLENT Dr. She explained things so we could understand what need to be done and made sure his care was followed through.

They got us an appt very quickly and she accomplished more in one visit than I’d been able to get figured out for my son in 6 mos with other providers. Great demeanor with kids & very knowledgeable.
