About Us

Avanti is a psychotherapy group practice based in Sammamish, WA that offers a wide array of services. We offer therapy, assessments and support from an integrated blend of Evidence-Based Therapeutic Modalities. As a team of professional therapists, we are committed to facilitating mental, emotional, and relational change in individuals and families.

Avanti was founded in 2017 by Dr. Cheryl D’ettorre and Dr. Bob Smith as Avanti Adolescent Services. Although Dr. Cheryl stepped down as owner in 2022 to pursue other aspects of her life (grandmother, gardener, traveler), she continues to practice at Avanti. Dr. Steph Regus took her place as co-owner of Avanti in 2023.

Adolescents are still a major focus of the clinic, the name was changed in 2022 to Avanti Psychological Services to reflect the fact that we also serve children and adults.
