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.
