Dr. Nancy Freitas Lambert

Clinical Director

Dr. Nancy Freitas Lambert is a Licensed Clinical Psychologist with extensive experience in clinical program oversight and the delivery of comprehensive mental health services. With a proven history of effectively leading clinical teams, ensuring high-quality treatment, and managing all facets of clinical operations, Dr. Lambert has successfully held leadership roles at prominent organizations. She served as Clinical Director at Serenity Knolls Treatment Center and at St. Vincent School for Boys, where she was responsible for implementing program philosophies, coordinating utilization reviews, and liaising with referring agencies.

Dr. Lambert’s expertise extends beyond traditional therapy into the realm of equine-assisted psychotherapy. As the Director of Wonder Equine Therapy and an EAGALA-certified Equine Specialist, she harnessed the transformative power of the horse-human connection to promote emotional growth and self-discovery. Her innovative approach helps individuals recognize relational patterns and build healthier relationships rooted in trust and self-awareness.

Her dedication to serving diverse communities is reflected in her work as Director of the Ritter Center Project, where she supervised interns and supported homeless individuals with complex needs, including PTSD, substance abuse, and dual or triple diagnoses.

Dr. Lambert holds a Doctorate in Clinical Psychology from the Wright Institute Berkeley. With her wealth of experience and commitment to high-quality care, she is a tremendous asset to Rosebay Behavioral Health.

What People Are Saying: Real Stories of Transformation

Rosebay is a wonderful program with amazing staff, therapists, and groups. I felt fully supported by the team, allowing me to piece together all aspects of my life, which had formerly fell to the wayside when my mental health was deteriorating. Rosebay helped me to lift myself back up mentally, spiritually, and physically. I was able to integrate the work I did with the team at Rosebay into my daily life. I am so grateful!
