Dr. Marks is so thorough and thoughtful. She really thinks about each patient uniquely.

Linda S.
We've had nothing but great experiences with Dr M-C and team. Her knowledge is up to date, she's willing to spend as much time as necessary with patients and parents.

Felicia Y.
Dr. Katie is exceptional with both of my kids. My 4 year old had an egg allergy and she was so amazing with him that he never minded getting allergy tested with her.

Mia F.
I can't recommend Dr Marks-Cogan enough! You can clearly tell that she cares about each and every one of her patients.
