Allison Ondocsin, LPC 
Licensed Professional Counselor

Allison is a psychotherapist who provides individual and family therapy to adults and adolescents. She is a Licensed Professional Counselor and has worked as the primary therapist for an eating disorder treatment center, a crisis specialist for those with persistent mental illness, an outpatient trauma counselor and a therapist in private practice. Within these roles, Allison sees people with a range of needs, including those managing mood/anxiety disorders, personality disorders, eating disorders, trauma history, issues with loss of identity, and those experiencing a lack of connectedness or balance in their lives.

Allison has a personal and professional understanding of how therapy can help someone to live more meaningfully and wholeheartedly. Therapy isn’t simply a process to fix something that’s broken. It creates the opportunity to thrive and truly experience and live life. By creating a safe space, Allison joins people as they tolerate and even lean into discomfort with vulnerability and self-compassion. In doing so, people can cultivate and nurture hope and resilience, resulting in a greater capacity for joy and engagement in their lives.

In the community, Allison has sought ways to be present for those who lack support and care, including as a board member for a nonprofit serving distressed families, a mentor and speaker promoting recovery and self-compassion, a case manager for a homeless shelter, and as a group therapist in a women’s jail.
