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.

I love Jenn. We have worked together for a while now and she's always great. I feel better after each session and empowered to tackle the challenges that I'm in therapy for (as well as anything else I can think of).
