My name is Abby Costello and I am a Licensed Professional Clinical Counselor, specializing in adolescent therapy. I work with pre-teens, teenagers and young adults to increase their effectiveness so they can feel more in control of their lives. Drawing on my experience in both school and private practice settings in Marin County, I have a strong understanding of how to meet clients where they are and provide personalized support that addresses their unique needs

​

I offer individual psychotherapy both in-person in Corte Madera and virtually through telehealth. Please reach out for a complimentary consultation to learn more about my services.​
