Mary O’ Neil was amazing. I have tried couple of therapist but none seem to fit me.
Mary O’Neil truly listens and is there to help. I felt heard, understood and cared for. The time for sessions were great and always on time. My therapy has been working out for me for the first time. After each session I felt a difference and I always felt so much better right after.
I highly recommend Mary O’Neil.
