Going into this meeting I was feeling quite anxious. Dr. Calahan was able to put me at ease. She’s very much a skilled psychologist who understands the limitations of her clients and is focused on ensuring treatment will cause no additional harm.

My husband and I have talked to several couples counselors and Jennifer has been the best. She’s given us steps to communicate better while in conflict. We are very grateful.
