Patti works collaboratively with each client to identify strengths, clarify goals, and build coping skills that support long-term emotional well-being.

With more than two decades of clinical experience, Patti specializes in treating anxiety, depression, and trauma-related concerns. She integrates Cognitive Behavioral Therapy (CBT), Dialectical Behavior Therapy (DBT), and mindfulness-based practices to help clients understand patterns of thought and emotion, regulate distress, and find greater balance in daily life. Her approach is warm, trauma-informed, and grounded in empathy—empowering clients to rediscover their capacity for hope and self-compassion.

Patti is particularly passionate about supporting women as they navigate significant life transitions, including midlife and later-life changes, postpartum challenges, and grief. She understands that these experiences can bring both loss and transformation, and she works with clients to process emotions, strengthen self-identity, and create meaning in new chapters of life. Patti also brings deep sensitivity to the experiences of first responders, military veterans, and individuals from diverse cultural backgrounds, fostering an inclusive and affirming space for healing.

Outside of her professional work, Patti finds joy in activities that nurture creativity and connection, including painting, crafting, music, gardening, and hiking. She values time spent with family and friends and embraces opportunities to bring mindfulness and gratitude into her everyday life.
