About My Clients

You may look like you're managing life well while privately feeling anxious, lonely, stuck in a relationship, or caught in patterns you understand but can't seem to change. I work with adults navigating anxiety, OCD, grief and loss, relationship difficulties, major life transitions, and questions of identity or belonging. Many of my clients want more than symptom relief—they want to understand themselves better and create lasting change.

My Background and Approach

Originally trained as a psychologist in Australia, I bring nearly two decades of clinical experience to my work in the US. I'm a Licensed Mental Health Counselor in Massachusetts and a Licensed Clinical Professional Counselor in Maine, providing therapy to adults through telehealth. My style is warm, straightforward, and engaged. I won't simply sit back and nod. We'll work together to understand what is happening, where recurring patterns may have come from, and what can actually help you move forward. My approach is integrative, with particular emphasis on Schema Therapy, Acceptance and Commitment Therapy (ACT), attachment theory, and cognitive behavioral approaches. Depending on what brings you to therapy, our work may explore longstanding relationship patterns and unmet emotional needs, develop practical ways of responding to anxiety or OCD, or help you clarify your values and build a life that feels more connected and meaningful.

My Personal Beliefs and Interests

I believe good therapy should be a place where you don't have to edit yourself to be accepted. I value curiosity, compassion, humor, and honest conversation, and I welcome clients across sexual orientations, gender identities, relationship structures, cultural backgrounds, and stages of life. As a gay man who grew up in Australia and has built a life in the US, I also appreciate that identity, belonging, relationships, culture, and major life transitions can be complicated. I aim to offer a space where these parts of life can be explored openly, without assumptions or judgment. Outside the therapy room, I value being active, spending time outdoors, travel, and continuing to learn. I believe meaningful change often comes not from becoming a different person, but from understanding ourselves more deeply and living more intentionally.
