How I Work

My Approach to Psychiatric Care

I believe that psychiatric care is most effective when it is holistic and collaborative. Medication can be an important tool, but it is only one part of a comprehensive treatment approach. Working together, we explore how your biology, environment, and daily routine interact.

Attentive, caring, and thorough. I take time to explain treatment options clearly and support you through each step. Many clients feel heard and understood in ways they have not experienced before.

I work best with clients who…

Are open to exploring their mental health concerns with honesty and curiosity, whether the focus is anxiety, depression, ADHD, mood regulation, trauma, or other complex symptoms.

In sessions, you can expect…

A thorough, personalized approach. We'll review your history and goals, then build a plan that may include medication, lifestyle support, and coordination with other providers.

At Riverside Counseling and Psychiatry, Emily works with clients from Ashburn, Leesburg, Sterling, and across Northern Virginia, and offers telehealth for patients throughout Virginia.
