HITH Clinical Services is a team of licensed therapists providing compassionate, evidence-based psychotherapy to adolescents and adults across Maryland, Washington DC, and Northern Virginia. According to the National Institute of Mental Health (NIMH), an estimated 15.4 million U.S. adults (6.0% of the adult population) live with a serious mental illness each year. We specialize in supporting this population, along with neurodivergence and complex mental health challenges — and we come to you. Whether sessions take place in your home, online, or in your community, our approach is grounded in a community integration model backed by decades of research.
Our licensed therapists draw from a range of evidence-based modalities, tailoring each treatment plan to the individual’s needs, goals, and real-world circumstances. Under the clinical oversight of Sarah Harte, LCSW-C, our Clinical Director with over 20 years of behavioral health experience, our approach includes:
“Staying the same protects you from the unknown.”
— Ross Ellenhorn, PhD, founder of ellenhorn (a national community integration program) and author of How We Change (and Ten Reasons Why We Don’t)
Our therapeutic approach is rooted in the community integration model — an evidence-based framework first formalized through the Program for Assertive Community Treatment (PACT) in the early 1970s. The original research, published in the Archives of General Psychiatry, found that a community-based treatment program significantly reduced the need for hospitalization compared with conventional short-term hospitalization plus aftercare (Stein & Test, 1980). More recent research continues to support this model: a 2025 study published in Psychiatric Services found that young adults with serious mental illness receiving community mental health-based integrated care were significantly less likely to have a medical emergency department visit than those in standard care — 26% compared to 33% (Brunette et al., 2025).
At HITHCS, we don’t wait for stabilization to begin community engagement — we embed it from day one. Our clinicians work with you in your home, your neighborhood, and the places that matter to you. This allows us to observe real-world challenges — around medication routines, daily structure, social connection, and long-term stability — and address them where they actually happen, with the people and environments already present in your life.
“Community integration means helping people develop the skills and resources they need to establish physical, psychological, and social connections within their community. This process enhances their independence, social inclusion, and overall quality of life.”
— Sarah Harte, LCSW-C, Clinical Director
There are real advantages to receiving support in the comfort and safety of your own home and community.
At HITH Clinical Services, we believe that meaningful change takes time — and we are in it for the long haul. Our licensed therapists build lasting relationships with clients, adapting their approach as needs evolve and goals shift. We don’t measure success by the number of sessions — we measure it by the skills you develop, the independence you gain, and the quality of life you build. For families across Maryland, Washington DC, and Northern Virginia navigating serious mental illness or neurodivergence, we are the team that stays.
