had this to say:
I started seeing Dr. Gillen about half a year ago. After being sick of what our normal health care system does for people who are struggling, but aren’t sick by their superficial metrics a friend told me about Mosaic. I am happy I made the change. My first appointment I felt seen and cared for and felt similar feelings every appointment I’ve had after that. I am forever grateful for Dr. Gillen.

I have been going to Dr. Gillen for 9 months now and I am so happy with her care! Dr. Gillen and her staff have been phenomenal! Dr. Gillen listens to my concerns and doesn’t make me feel silly asking questions. She takes the time and you can tell she genuinely cares about her patients and their concerns. She has helped me alleviate a lot of my health and mental concerns. I can’t recommend her clinic enough!!
