A New Theory of Teenagers: Seven Transformational Strategies to Empower You and Your Teen

A guide for families to thrive in the midst of the tumultuous teen years–and the culmination of the author’s twenty-five years of experience in both conventional psychology and alternative methods.

In her decades of practice and academic research, Dr. Christa Santangelo, a psychologist and assistant clinical professor at the University of California-San Francisco, has seen many relationships devastated by the emotional hurricane that teenagers can inflict on a family. Yet Dr. Santangelo also understands how that conflict can be resolved and a new way forward mapped together between parents and teen. In A New Theory of Teenagers, she gives parents the advice, tips, support, and big-picture overview needed to see the teen years as an opportunity for growth and positive relationship changes. With counterintuitive steps (such as “Endure Emotions”), she offers hope and empowerment. Dr. Santangelo asserts that parents have a far greater impact on conflict with their teen than they may realize, metaphorically handing parents back the power to shift the situation to harmony.

My passion is connecting people to their passion, their purpose. When we are connected to our purpose, we have a momentum that expands and enlivens us. When we are disconnected from the truth within there is a sense of futility to our experience.

Depression, anxiety, eating disorders, relationship difficulties, and other problems we experience are often symptoms of our disconnection from our truth. My work with you is the process of reconnection to that place of true knowing.

  • When do I feel the best?
  • Truly like myself?
  • The most alive?

My approach to therapy is the process of answering these questions and identifying the blocks to these optimal states of experiencing life. I believe that supporting clients in connecting to their essential and most alive selves is a gift I am privileged to share.

One area of expertise is adolescents and their families.

I work with teens to help them identify and develop strengths and the capacity to live healthy, productive lives.

I also work with individuals, couples, and children and am inspired by people of all ages who are interested in transformation.
