Licensed Associate Marriage and Family Therapist in Pennsylvania
I believe therapy can be a place where you feel understood, accepted, and supported while also having the space to look honestly at the patterns, relationships, and experiences shaping your life. We are social beings, and while there is something deeply valuable about individual reflection, I believe meaningful change often happens in relationship. My goal is to create a therapeutic space that feels safe, respectful, nonjudgmental, and genuinely human.
My own path to becoming a therapist grew out of my experience as a client. While navigating loss, major life transitions, and starting a family, I became increasingly curious about the ways our relationships and family histories shape how we understand ourselves and the choices we make. That process eventually led me away from a decade-long career in engineering and toward Marriage and Family Therapy, where I found an approach that aligned more closely with my values and my interest in understanding people within the relationships, cultures, and larger systems that surround them.
I work with individuals and couples navigating life transitions, relationship concerns, trauma, identity development, and the challenges that can come with becoming a parent or building a family. I am especially interested in working with people who find themselves at a turning point, whether that means changing careers, entering a new stage of adulthood, becoming a parent, reconsidering parts of their identity, or simply realizing that the way they have been living no longer feels right. I am particularly drawn to supporting couples transitioning into parenthood and young parents adjusting to the emotional and relational changes that come with building a family.
My approach is collaborative and active. I want therapy to be a place where you can develop greater self-understanding and self-acceptance, become curious about the different parts of yourself, and identify patterns that may be getting in the way of the life or relationships you want. I may offer feedback, ask challenging questions, use humor, or gently point out patterns that emerge in the room. At the same time, I believe you are the expert on your own life, and our work should reflect what is meaningful to you rather than imposing someone else's idea of what your life should look like.
I draw from Narrative Therapy, Emotionally Focused Therapy, Internal Family Systems, Acceptance and Commitment Therapy (ACT), and trauma-informed approaches. I also strive to practice in a culturally attuned way, recognizing that our identities do not exist separately from the social and cultural contexts in which we live. My hope is that therapy becomes not only a place to better understand yourself, but also a space to experiment with new ways of relating to yourself, your partner, your family, and the people around you.
Outside of therapy, I enjoy staying active and spending time outdoors, including cycling, strength training, running, hiking, and playing disc golf. I also love cooking, traveling, experiencing new places and cultures, and having long conversations with the people I care about.
