About ABC Health

Rooted in experience. Guided by excellence.
Led with purpose.

ABC Health provides compassionate, individualized ABA therapy for individuals ages 3-21. Grounded in lived experience, guided by clinical excellence, and led by proven leadership, we partner with families to create meaningful progress that lasts.

Our Purpose

At ABC Health, everything we do is rooted in a deep commitment to families, children, and the professionals who support them. Our work is guided by real-life understanding, strong clinical standards, and purposeful leadership that puts people first. This foundation shapes how we serve families today and how we lead the future of ABA therapy.

Our Vision

Our vision is to empower families and transform lives by setting a higher standard in ABA therapy, one rooted in evidence-based practice, thoughtful leadership, and genuine human connection. We strive to lead with integrity, inspire progress, and shape a more inclusive and supportive future for every child and family we serve.

OUR FOUNDER

At ABC Health, we understand the hopes, challenges, and questions that come with raising a child on the autism spectrum, because we’ve been there too. Our founder, Lila Ayyad-Alharsha, M.Ed., LBA., BCBA., IBA, brings more than 28 years of experience and a unique perspective to ABC Health. As a parent of an adult on the autism spectrum, she built the company with a deep understanding of both the professional and personal sides of autism care.

With a background in early childhood education, special education, school leadership, and, as a Board Certified Behavior Analyst, Lila approaches every family with a 360° perspective — as a parent, educator, and clinician.

Our Process: What to Expect

Assessment & Progress Monitoring

Every successful therapy plan begins with understanding the child as a whole. Our assessment process is designed to be both thorough and family-friendly, ensuring parents feel informed and involved from the start.

Initial ABA Assessment

We begin with a comprehensive evaluation using tools such as the VB-MAPP, ABLLS-R, PEAK/PCA, or AFLS to identify strengths, learning styles, and developmental needs. This information guides each child’s individualized treatment plan.

Functional Behavior Assessment (FBA)

When behaviors present challenges, we use data-driven assessments to identify the function (the “why”) behind those behaviors. This allows us to teach meaningful, functional skills that support communication, independence, and long-term success. 

Ongoing Progress Monitoring
We track progress continuously, using measurable data and frequent reviews to ensure each child’s program remains effective. Parents receive clear updates and visuals to make progress easy to understand.
Collaborative Review Meetings
Regular team meetings with your BCBA ensure transparency and shared decision-making, keeping everyone — from parents to educators — aligned on each child’s growth and goals.

Our Core Values: E.M.P.O.W.E.R.

Our values guide how we care for children, partner with families, and support one another as professionals.
E.M.P.O.W.E.R. reflects both what we believe and how we show up every day.

Excellence

We are committed to high-quality, evidence-based care and continuous growth. Excellence means thoughtful clinical decisions, ethical practice, and a commitment to doing what is best for children and families.

Motivated

Our work is purpose-driven. We value professionals who are motivated to learn, grow, and make a meaningful impact through intentional, compassionate care.

Positive & Proactive

We approach challenges with solutions in mind. Clear communication, collaboration, and proactive problem-solving help us create consistency and progress across teams and settings.

Open-Minded

We welcome diverse perspectives and value curiosity. Open-mindedness allows us to learn from one another, adapt thoughtfully, and provide individualized care that respects every child and family.

Welcoming

We strive to create an environment where children feel safe, families feel supported, and team members feel valued. A welcoming culture is foundational to trust, connection, and growth.

Ethical & Professional

Integrity and professionalism guide every decision we make. We hold ourselves to high ethical standards and believe quality care begins with accountability and respect.

Reflective

We believe growth comes from reflection. Through supervision, feedback, and self-evaluation, we continually strengthen our practice and our impact as clinicians and teammates.

An Engaging Learning Environment

Our 4000+ sq. ft. clinic is thoughtfully designed to create a welcoming, child-centered experience where children feel safe, families feel at ease, and progress, big and small, is intentionally supported and celebrated every day.

We invite you to contact us to schedule a tour of our clinic and experience our culture for yourself. You will LOVE it!
