My Philosophy of Care

In my work with people who have eating disorders, I have witnessed the violence and abuse inflicted upon bodies that have the audacity to violate the rules of what is deemed acceptable. These bodies—deserving of love, medical care, visibility, and existence—face unique battles, often overlooked by a system clinging to outdated ideals. People with eating disorders, living in a larger bodies face multiple oppressions. Their eating disorders typically go undiagnosed, overlooked by a medical and mental health system perpetuating harmful stereotypes. Behaviors considered disordered in thin individuals are normalized and even prescribed for fat folx. Beneath the surface lies a web of oppression: patriarchy and white supremacy. These forces shape our beliefs about self-worth, maintaining social and economic power dynamics. Marginalization keeps us compliant, feeding into a consumer culture that promises solutions to our perceived flaws—our feelings, our bodies—when, in reality, we are not broken. Individuals internalize their own oppression, blaming themselves for their struggles. Yet the system is rigged—the house always wins. Enter the Health at Every Size® (HAES®) framework. By dismantling fat phobia, diet culture, and misogyny, we reclaim power and define our existence. It’s not merely about healing; it’s about liberation. I work with my clients on learning to claim the life they want, in the body they have, even if the world is not build for them.

About Me & My Practice

As a seasoned Clinical Psychologist with over a decade of experience, I specialize in treating eating disorders. My therapeutic approach combines behavioral and dynamic modalities within an intersectional feminist framework, Health at Every Size® (HAES®). At Birch Tree Psychotherapy, the small group practice I founded in 2012, we provide personalized care to individuals struggling with their relationship to food and body image. Size inclusivity and weight neutrality are core principles in my clinical work, how I train my trainees, and how I engage with the community. My work centers on women’s and gender-expansive folx’ connections with their bodies. I particularly enjoy working with people in larger bodies who have eating disorders and disordered eating. As I have grown in my practice, engaging in professional training and community outreach have been exciting avenues of development. I actively engage in presenting HAES®-aligned seminars as well as directly providing supervision, and consultation to other professionals. My current project is focused on addressing implicit anti-fat biases among clinicians.
