Dr O is extremely knowledgeable, helpful, attentive and responsive. Most importantly, my teen enjoys working with him. She enjoys his warm personality and that matters more than anything else. We are in the middle of the process, but I chose to write my review now because the experience has been so positive. I feel confident and secure going forward knowing that we have his guidance and wisdom, especially during these uncertain times of 2020. WE are so grateful and highly recommend him.
