Sometimes the hardest part is just deciding to reach out. I work with children, adolescents, and adults who are navigating anxiety, trauma, family stress, and the weight of experiences that are hard to carry alone. I am affirming and experienced in working with LGBTQIA+ and transgender individuals, and I welcome clients across a wide range of backgrounds and life circumstances. Whether you are dealing with the effects of trauma, anxiety that has become hard to manage, or stress that has quietly built up over time, I want our work together to feel like a genuine partnership.

I have been in private practice for 20 years with my specialty focusing on individuals resolving historic traumas and women balancing all of the complications of womanhood in a fast paced, demanding world. My style is informed from my diverse experience. I have worked in adolescent residential treatment, FBI consulting, an expert witness and a graduate school professorship; all the while working with my private practice clients. In the last several years, I have been sought out as a corporate consultant and speaker to discuss how our negative experiences and traumas shape our behaviors as high intensity professionals.

The untapped magnificence I see in my clients never ceases to inspire and amaze me. Anyone who is willing to do hard work is already a gift to this World! I've grown bored of many things in my life but this work....never!

I specialize in Solution-Focused Brief Therapy, a practical and modern approach that helps you

move forward instead of getting stuck in the past. If you’ve tried therapy before and felt it missed

the mark, or if you’re hesitant to begin, my style is supportive, goal-oriented, and centered

around real progress. Together, we’ll focus on what’s already working, build on your strengths,

and create meaningful steps toward lasting change.

You might look like you have it together from the outside: steady job, functioning relationships, managing the day to day. But inside you're running on fumes, and you're tired of just pushing through. I work with young adults, college students, and adults navigating anxiety, stress, life transitions, and the frustration of feeling stuck without knowing why. I'm also an Army veteran, and I bring firsthand experience of what pressure, resilience, and major transitions actually demand. If faith is part of how you make sense of life, it's welcome here. If it's not, that's fine too. Clients often tell me I'm surprisingly easy to talk to.

My priority is to provide a safe, compassionate, and non-judgmental space where you feel heard, respected, and supported. With over 40 years in healthcare—including service as a former Navy Nurse Corps Officer and retired military veteran—I bring values of resilience, trust, and teamwork into every therapeutic relationship. I view care as a partnership and work to empower you to take an active role in your mental health.
