A personal note
Why I Do This Work
As a clinical psychologist, neurofeedback and biofeedback provider, and somatic practitioner, I consider it a privilege to cultivate meaningful, collaborative relationships in my work – relationships specifically intended to support resilience in clients. I work with clients to find relief from and deeper meaning in their difficulties, and believe that, when carefully attended to, dark moods, unwanted habits, difficult symptoms, and disturbing thoughts, feelings, and behaviors serve as doorways through which a deeper relationship with oneself is possible.
There is a secret love hiding in each problem.
Detailed bio
We all have the potential to lead a fulfilling life. Difficult challenges may keep us from reaching that potential, and we can find ourselves stuck in repetitive cycles of suffering. I offer somatic therapy, neurofeedback, and biofeedback with a focus on the alleviation of symptoms through inner transformation.
With close attention to the unresolved emotional pain and nervous system dysregulation that drive symptoms, I help clients find resilience within the difficulties they face. In my practice you will find a welcoming space where you belong and are free to explore your past pain and triumphs, current challenges and strengths, and hope for the future.
I am currently accepting new clients. I offer neurofeedback for children, teens, and adults, and biofeedback, somatic therapies, and psychotherapy for adults. Sessions are held in person at my Petaluma office.
I have particular expertise in adult psychotherapy for trauma, anxiety, depression, LGBTQ+ issues, loss, shame, and relationship problems, drawing on time-tested and evidence-based approaches suited to each client's unique needs. I am a seasoned neurofeedback provider who has worked with a wide-range of clinical issues, including the painful mental health, neurodevelopmental, neurocognitive, and mind-body issues that negatively impact clients' day-to-day life.
