DISCOVERY PSYCHOTHERAPY CENTER - Key Persons


Christopher J. Barker

Discovery: I like the name because it speaks to me of finding, uncovering and celebrating that which was already there. We cannot create solutions or new behaviors as easily as we can find our way. I cannot change you, but I will try to help you discover what you need to make your life more enjoyable. I received a Master of Science in Counseling Psychology with a specialization in assessment from Radford University, a Clinical Psychology Master of Arts from the New School for Social Research, and a Ph.D. from Seton Hall University. My experience began long before I finished my degrees. I was a peer counselor in college and have always​been the one my friends came to with problems.The way their lives shaped their needs propelled me in the direction I followed to the completion of my studies. My training was in Clinical Psychology, with a specialty in Child Clinical Psychology and I am a licensed psychologist in New Jersey. I was raised with an awareness and immersion in my family's Native American heritage and have always been an advocate for cultural awareness and diversity. I have done extensive research and have presented papers on suicidal behavior as it relates to culture, and organized a panel discussion of multicultural perspectives on children in crisis for the New Jersey Psychological Association.

Jennifer C. Sumerlin

In therapy it all begins with effective communication and ironically, the key to good communication lies in the art of being silent. I believe that communication is a foreign language in and of itself where one must first learn the basics and be able to translate before speaking to others. I love helping my clients grasp this "language" in hopes of being able to have a conversation without words or actions that can be grossly misinterpreted.
