About Us

At Dodini Behavioral Health we are committed to helping our clients have better lives through emotional and psychological growth, personal development, and balance. We strongly believe it is personal growth, not just managing symptoms, that brings lasting happiness. Sometimes symptoms are the body’s way of alerting us to underlying problems. Once we address the underlying problems we can move on to finding personal fulfillment, professional success, and improved intimacy and connections to others. That is the fun part! It’s also the part we love and feel so lucky to be able to participate in with so many great people.

Aaron Dodini, Ph.D

I’m the oldest of ten kids. I think that may mean I was born to become a psychologist!  My early life experiences have prepared me well and gave me the skills to be a great psychologist. After spending some time in my ancestral home in the Swiss Alps and finishing my undergrad degree in Psychology, I enrolled at Virginia Tech’s Marriage & Family Therapy master’s degree program. Two years into that three year program, I began what would be a six year Ph.D. program in Clinical Psychology at Catholic University.  I attended the two schools concurrently. I don’t recommend concurrently attending to two graduate schools while at the same time expecting your first child. That would be the NON-balanced approach to living. Needless to say, after nine years of graduate work, four children, and two decades of marriage, I have come to embrace a philosophy of life balance. Over the 17 years I’ve been in practice, it’s been my great honor to help others identify and pursue their own version of growth and balance. I believe in the basic truth that we grow and learn life’s greatest lessons in the company of others. It is on this core philosophy that my practice is established.

Dave Dayton, Ph.D

Like all 12 year old boys on my dad’s side of the family, I was sent to work on my uncle’s cattle ranch in Wyoming for the summer. Job responsibilities included: herding cattle, throwing rocks out of fields, and moving sprinkler pipes in mosquito-infested alfalfa at 5:30 every morning. We were told that working on the ranch would build work ethic and character. You can imagine my disappointment when it occurred to me that neither of those things happened. Instead, I returned home at the end of the summer with the reaffirmation that my calling in life was to make movies, not work on a cattle ranch.

Sonia Kahn, Psy.D

I have always been fascinated by how we, as humans, make sense of the world, be it through artistic expression, research, debate, or therapy. As an undergraduate, I studied both psychology and English to explore the interconnections between literature and psychological constructs like emotion, thought, and human connection. A few years later, I decided to focus on psychology, leaving writing as a hobby, earning my Doctorate in Clinical Psychology from The George Washington University. As a therapist, I get the opportunity to help my clients hear themselves differently, rewrite their histories, share stories they have never had the opportunity to tell, and gain an understanding of themselves that empowers change.

Kerstin Perini, M.A.

I view therapy as a joint venture in healing and growth where everyone’s situation and experiences are unique. I try to allow for creativity to infuse my every day and believe that feeling supported can transform the way we view our worlds. I also believe that our mind and body are closely integrated and that taking an intrinsic and holistic approach to health can help a person more effectively cope with anxiety, trauma, grief, and depression.

Joseph Schmidt, Psy.D.

I took the scenic route into psychology as my profession. I started out working in public libraries, later studied theology, and worked in public health policy before beginning my training in psychology. Saying “Yes” to a number of other paths eventually led me to do what I love – namely working with people who need a space to stop, reflect and consider how to move forward with their lives.

Michael Magenheimer, Psy.D.

Before discovering psychotherapy and the world of psychology, my first passion was outside. Rock climbing, mountain biking, outdoor leadership and team building; these were more than hobbies, they became my first career, providing me financial support throughout graduate school, and providing adventures and stories to last a lifetime. But more important than all others, these things helped me find my best and lifelong friends. This thread, the importance of relationships and how they change our lives, runs through my life both outside the office as well as within and is reflected in my work with clients. The core of my work within psychotherapy is focusing on how we relate to others, and how understanding and examination of the ways in which we relate can empower us to live more genuine, healthy, and fulfilling lives.
