Couldn’t fully do the skin test since no one let me know ahead to be off meds. Not the friendliest staff and a little disorganized and spacey. Will not return or recommend.

Dr. O'Connor was a great listener and made me feel comfortable, as this was my first time seeing an allergist due to new allergic symptoms. The staff were friendly and helped me schedule a follow-up easily.
I highly recommend Dr. O'Connor as your allergist.

I have recommended multiple of my friends already after just one appointment. they explained everything very thoroughly and listened to me and it really felt like a partnership to try and get to the root of the issue and make a plan with me moving forward. Highly recommend. ?
