Message to clients

"Welcome! If you're here, that means you're looking for support as you grow and heal. Everyone can use some help with this at some point or another, but it can be intimidating to reach out. My job is to create a place where you feel safe and accepted as you start to explore yourself and ways you might like to grow or change. I believe everyone has wisdom inside them that can help along this journey. Even when you're feeling stuck, we can work together to tap into this wisdom and help you find your best way forward."

Treatment approaches

Cognitive Behavioral Therapy (CBT)In cognitive behavioral therapy, you work with a therapist in a structured way, attending a limited number of sessions. Cognitive behavioral therapy helps you become aware of inaccurate or negative thinking, so you can view challenging situations more clearly and respond to them in a more effective way. (learn more)
Existential Therapy Existential therapy is a therapy approach that both embraces human potential and recognizes human limitation. The breadth of existential theory falls into four major themes, which it sees as the root of most psychological problems: 1) Death, 2) Freedom (& Responsibility), 3) Isolation, and 4) Meaninglessness. (learn more)
Internal Family SystemsIFS is a type of therapy that views the mind as a combination of relatively discrete subpersonalities each with its own viewpoint and qualities that interact with one another. IFS aims to understand how these collections of subpersonalities are organized and promote harmony among them. (learn more)
Mindfulness PracticesMindfulness practices include but are not limited to developing awareness, attention, and remembering. In mindfulness-informed therapy, clients develop tools to become aware of what is occurring within and around them, so they can begin to untangle from mental preoccupations and difficult emotions. Self-acceptance and compassion are also core elements of mindfulness-informed therapy. (learn more)
Psychoanalytic TherapyPsychoanalytic therapy tends to look at experiences from early childhood to see if these events have affected the individual’s life, or potentially contributed to current concerns. This form of therapy is considered a long-term choice and can continue for weeks, months or even years depending on the depth of the concern being explored. Psychoanalytic therapy aims to make deep-seated changes in personality and emotional development. (learn more)
Supportive TherapySupportive psychotherapy is used primarily to reinforce a patient’s ability to cope with stressors by giving clients the opportunity to express their feelings and thoughts about the issues. Clinicians help patients learn how to move forward and make decisions or changes that may be necessary to adapt, either to an acute change, such as the loss of a loved one or severe disappointment, or to a chronic situation, such as an ongoing illness.
