Dr. Sandra M. Athanasios is a licensed clinical psychologist with over 10 years of experience across hospitals, community mental health and substance abuse clinics, schools, and forensic and disability evaluations, including Social Security and worker’s compensation contexts. She holds a Doctorate of Psychology from The Wright Institute in Berkeley, CA and a Master's Degree in Counseling Psychology and Industrial/Organizational Psychology from Golden Gate University in San Francisco, CA. Dr. Athanasios is a Qualified Medical Evaluator (QME) and a Certified Sex Therapy Informed Professional (CSTIP). She also serves as a clinical supervisor for doctoral-level trainees, providing assessment and therapy to children, adolescents, and adults across a range of psychiatric and dual-diagnosis settings.
 

At Therapy Partners of the Peninsula, Dr. Athanasios offers individual therapy for adults, with a particular focus on emerging and young adults navigating the unique challenges of that life stage. Her clinical areas include interpersonal difficulties, depression, anxiety, mood disorders, trauma and PTSD, and life transitions. As a Certified Sex Therapy Informed Professional, she also works with individuals and couples exploring questions related to relationships, intimacy, and sexuality — bringing a thoughtful, nonjudgmental approach to topics that can be difficult to discuss elsewhere.

 

Dr. Athanasios also provides comprehensive psychological assessments for children, adolescents, and adults. Her evaluations focus on helping clients, families, and providers better understand presenting concerns across areas including personality, mood and emotional functioning, cognitive abilities, developmental factors, and trauma. Through testing, clients gain a deeper understanding of their strengths and challenges, the origins of any difficulties, and concrete recommendations to guide next steps in treatment.
 

Across all her work, Dr. Athanasios draws on evidence-based practices through a trauma-informed and relationally focused lens, with the goal of creating a collaborative space where clients feel genuinely supported.

In her spare time, Dr. Athanasios enjoys hiking, reading, and exploring new places.
