Get to Know Dr. Hernandez-Jimenez

I am a licensed clinical psychologist at Old Town Psychology. I conduct comprehensive psychological and psychoeducational assessments and provide individual therapy for children and their families. 

I am passionate about providing clarity during psychological assessments to help clients understand their areas of strength to be leveraged and areas of challenge that can be further supported. My approach is strengths-based, neurodiversity-affirming, and holistic, rooted in disability justice and advocacy for systemic change. Throughout the process, I use these frameworks to cultivate a secure, comfortable environment to suit each person’s needs, understand test findings within each person’s unique context and background, and think creatively about meaningful recommendations and strategies to optimize daily functioning and well-being. I have experience conducting evaluations in schools, universities, clinical and research hospitals, and community mental health centers in English, American Sign Language, and Spanish. From this, I have gained a deep understanding of special education services and educational advocacy to help children and their families navigate these processes, as this can sometimes feel confusing and overwhelming. 

I also provide individual therapy and specialize in working with children and families, with a particular interest in early childhood development. I am especially passionate about working with marginalized community members who may have had difficulty receiving mental health care in the past or are engaging in therapy for the first time, children with developmental disabilities (ADHD, Autism Spectrum Disorders, Intellectual Disabilities, etc.), and children with chronic illnesses. I also have extensive experience working with adolescents and young adults, addressing anxiety, traumatic stress and adjustment, phobias, childhood aggression and acting out behaviors, parent-child dynamics, parental stress, grief and life changes, OCD, identity and cultural exploration in young adulthood, and depression. My approach includes evidence-based practices such as Cognitive Behavioral Therapy (CBT), Acceptance and Commitment Therapy (ACT), Dialectical Behavior Therapy (DBT), mindfulness, and parent training, and I regularly incorporate art, play, and creative activities to help clients express themselves more fully. During therapy, I collaborate with clients to develop goals together, regularly check in to evaluate progress, and adjust my approach to meet each person where they are. Amidst an increasingly stressful world that we are navigating each day, my goal is to build a space for you to remain present, develop a sense of safety, build confidence in managing challenges, become rooted in what is important to you, and make meaningful changes to your life and those of your communities.

I earned my Ph.D. at Gallaudet University in Washington, D.C., where I gained specialized training in supporting mental health and psychological services with the Deaf, Hard of Hearing, Deaf-Blind, Deaf-Disabled (DHHDBDD) communities as a hearing ally. I completed my two-year postdoctoral fellowship at George Mason University Center for Community Mental Health, and my predoctoral internship with the Mid-Atlantic Internship Consortium at The MECCA Group. During my doctoral program, I received training at the Gallaudet University Counseling and Psychological Services, National Institutes of Mental Health’s neuropsychology consult service, The Lourie Center’s therapeutic nursery program, and MedStar Georgetown Center for Wellbeing in School Environments. I also conducted research with Gallaudet University’s Visual Language and Visual Learning lab and worked for Gallaudet’s Institutional Review Board for several years during my training.
