I believe that one of the most important things a therapist can do is offer a place where people feel accepted for exactly who they are. When people feel accepted they are more comfortable sharing their stories, working towards change, and accepting themselves. With the support of a therapist, it is possible to gain a better understanding of one’s self, improve relationships, better manage stress, see things from a different perspective, and replace what is not working with what might work better.

In my previous career I was a teacher for over a decade. What I loved most about my work was supporting children’s social and emotional development along with partnering with their parents. When I decided to go back to school to get my MSW, I initially thought I would focus only on therapy with children. I spent my first year of training doing individual and group therapy with children at Horace Mitchell Primary School in Kittery. My second year, however, I sought a placement as a therapist in the adult services department at Seacoast Mental Health Center in order to round out my training. I found that I really enjoyed working with adults. After graduating, I stayed on at Seacoast as an adult therapist for two more years. I have experience working with people with a range of needs- from those seeking help managing general life stress to those living with severe mental illness. I now enjoy working with both teenagers and adults.


Types of Therapy

  • Acceptance and Commitment (ACT)

  • Attachment-based

  • Cognitive Behavioral (CBT)

  • Dialectical Behavior (DBT)

In therapy with me you can expect a variety of approaches, tailored specifically to you, that will help you better understand yourself and others, gain awareness and insight so you can start making changes that will improve your relationship with yourself and the important people in your life, and increase general life satisfaction. I also pay careful attention to whether patterns that are showing up in your relationships outside the office may be showing up in the therapy relationship, so they can be addressed as they are happening in a place free from criticism. You can expect periodic check-ins about how you think things are going in therapy, reflection on progress, and shifting the area of focus as needed. I do not believe in a rigid, one-size fits all approach to therapy. Instead, I offer a client-centered, flexible style, that balances seriousness and lightheartedness, and leaves clients feeling like they have finally found just the right fit.
