About Dr. Zentman

Dr. Zentman

My fascination with psychology is rooted in my childhood. Growing up as a first generation American in a three generation European family, I had a front row seat to the challenges of acculturation that my parents and grandparents dealt with every day. My unspoken task was to manage the interface of two cultures, a confusing and perplexing undertaking.

This early experience made me curious about what makes people tick, how families function, and the impact of culture on families and individuals. In college, I discovered that the field of psychology offered the questions, answers, and explanations I was looking for. After more than 40 years in the field ~ and on the planet! ~ I have a good sense of people and their relationships — how they work and the obstacles that can disrupt intimacy.

In addition to providing psychotherapy with individuals, couples, and families, I teach and supervise other psychotherapists. Teaching keeps me fresh and informed and provides opportunities to share my knowledge and experience which has been very rewarding.

My current focus is teaching couple therapy. All psychotherapy is consequential since the quality of an individual’s life is at stake. But with couples, the immediacy of their conflicts and difficulties raises the stakes. A long-term relationship may be floundering and at risk of dissolution and, with it, the possible disruption of children’s lives. For this reason, treating couples has always felt like a compelling responsibility.
