My goal as a therapist is to provide a safe environment where people can comfortably explore their longstanding, repetitive patterns, work through past trauma, integrate previously disowned parts of self, and discover their inner strengths. Whether you seek an experiential, cognitive-behavioral, dynamic, or integrated clinical approach, I will meet you where you are in your journey, adapting my methods to best support your process.

My approach to therapy is holistic, integrative, and draws heavily from psychodynamic, attachment, and developmental theories. In our work together, we will explore how early life experiences shape your current thoughts, emotions, and relationships. This exploration helps to deepen our understanding of the ways past experiences may still influence your present life. I practice from a relational frame, integrating internal family systems (IFS) and somatic interventions to work collaboratively with my clients in identifying the root causes of their symptoms. Our work may also include examining behavioral and interpersonal patterns, helping you become more aware of how these manifest externally, while also uncovering the unconscious forces that may contribute to these struggles. Using the therapeutic relationship as a vehicle for change, I am committed to helping my clients gain insight and self-awareness, empowering them to make intentional decisions that align with their values and alter their current experience.

I work closely with clients, utilizing a range of tools to better understand their unique challenges and strengths. One of these tools is psychological assessment, which allows us to take a deeper, more nuanced look at your cognitive, emotional, and behavioral patterns. This process goes beyond gathering test results and reducing problems down to diagnosis; its an opportunity for us to collaborate, placing the findings in the context of your everyday experiences and personal goals. Through this, we can gain greater insight into the root causes of your difficulties and identify pathways for positive change.

Collaborative / Therapeutic assessment can be particularly useful when there are questions about various behavioral, interpersonal dynamics, or life challenges that are impeding progress, whether in school, work, relationships, or daily routines.

I work with individuals across the lifespan facing challenges including complex trauma, anxiety, depression, ADHD and executive dysfunction, obsessive-compulsive tendencies, life transitions, grief, boundary issues. I enjoy working across all types of diversity, as well as intersecting sexual and gender identities. 

Additionally, I specialize in helping patients understand their cognitive, emotional, and personality patterns through comprehensive psychological assessments. My approach is tailored to meet the needs of children, adolescents, and adults - especially those who feel stuck or uncertain about why previous interventions haven’t worked, or for those looking to deepen their

understanding of their inner world and develop sustainable strategies for growth.

My therapeutic style is relational, collaborative, compassionate, non-pathologizing, and insight-oriented. I believe in the transformative potential of the therapeutic relationship and aim to form strong emphatic connections with my clients where they feel valued, seen, and heard.
