A Bit About Me

I’m Dr. Zimmitti, the Founder and Clinical Director of Georgetown Psychology. As a licensed psychologist with over 25 years of experience, I specialize in evaluating and treating children, adolescents, and adults. My primary focus is conducting evaluations to identify neurodivergence and co-occurring conditions such as ADHD, Autism, learning differences, anxiety, depression, and trauma. Through these assessments, I empower clients with the clarity and understanding they need to help them thrive.

I provide neurodivergent-affirming, gender-affirming, and culturally responsive evaluations, working collaboratively with clients to ensure the results resonate with their experience. The cornerstone of my approach is creating a safe environment where clients feel comfortable to be themselves. Establishing rapport helps children feel connected and valued, reduces anxiety and stress, and increases engagement in the testing process. This connection also allows me to observe natural behaviors and interactions, offering valuable insights that test scores may not reveal. My relationship with families extends beyond the assessment process. I am happy to assist in accessing resources in and outside our practice, collaborate with other professionals, and coordinate with schools to develop accommodation plans.

My Education, Training & Community Involvement

I earned my Ph.D. from the California School of Professional Psychology and relocated from Los Angeles to complete my training at Georgetown University Hospital’s Center for Child Development. After earning my degree, I received additional training in community mental health and school settings. I founded Georgetown Psychology to increase access to mental health care and provide a broader range of services with a team of highly trained clinicians.In addition to my clinical work, I am deeply committed to supporting youth mental health in our community, providing staff development workshops, teacher trainings, and parent webinars. I serve on the Board of Directors for Resilience Across Borders, a non-profit organization that provides resilience programming to students in under-resourced communities. My previous board memberships include the DC Rape Crisis Center, and District of Columbia Psychological Association, and the State Advisory Panel on Special Education for the District of Columbia. I mentor and supervise early career psychologists and have served as an Assistant Clinical Professor of Psychology at George Washington University.

Throughout my career, I’ve been featured in numerous media outlets, including CNN, ABC7, The Washington Post, The Huffington Post, Today, Parenting Magazine, BBC, and ADDitude Magazine, to share my expertise on child mental health and parenting topics.
