Low Intensity Support Services (LISS) — and DDA respite
LISS is Maryland's flexible fund for families and it is broader than most people realise: it pays for respite alongside assistive technology, childcare, home and vehicle modifications and personal care. It serves children living at home with their families and adults living in their own homes, and does not require you to hold a waiver. DDA also funds respite directly, in or out of the home, planned or in an emergency.
LISS operates on an annual application cycle with limited funds — apply as early in the fiscal year as you can rather than when you reach crisis point.

ARCH National Respite Locator
A free national database of respite providers searchable by state and locality — home care agencies, community-based organizations and state programs. The single best starting point for finding respite anywhere in the country, and it is the tool state agencies themselves point families toward.

Before you pay out of pocket, check what your state's Medicaid waiver funds — respite is covered by nearly every state waiver, and many families never think to ask.
Most states run one
Your state's Lifespan Respite Care Program
Lifespan Respite Care Programs are federally seeded, state-run programs that help families of any age and any disability find and pay for respite — often including vouchers or subsidies that do not depend on having a Medicaid waiver. Most states have one, they are chronically under-used, and they are rarely mentioned by anyone else in the system.

Week-long camps hosted nationwide
iCan Shine (iCan Bike)
Teaches people with disabilities to ride a conventional two-wheeled bicycle, using adapted roller bikes over a week-long camp that gradually transfers balance to the rider. Learning to ride a bike is a milestone a lot of autistic children are quietly written off for, and this is the program that most reliably delivers it. Camps are hosted by local organizations across the country, so availability is by host town rather than by chapter.

Coverage and plan participation change often, so confirm directly with the provider before your first appointment.
Where can I find ABA therapy in St. Mary's County?
ABA providers serving St. Mary's County are listed in the ABA therapy section of this page, with phone numbers and websites. Many deliver services in the family's home or at school as well as in a clinic. Ask about waitlists when you call — they vary widely and change month to month.
Can autism therapy happen at home in St. Mary's County?
3 providers serving St. Mary's County deliver services in the family's home. Many children do better in a familiar setting than in an unfamiliar clinic room, and in-home visits remove the travel burden.
Does Medicaid pay for autism services in Maryland?
Maryland families can apply to the DDA Community Pathways Waiver, a Medicaid waiver that can fund respite, therapies and in-home support. The typical wait is 3–10 years, but your priority category matters more than your date, and your place is usually set by the date you apply — so applying early matters even if you are unsure what services you need. Many waivers also disregard parental income, so families who don't qualify for regular Medicaid often still qualify here.
What if I can't find an autism provider in St. Mary's County?
If none of the St. Mary's County providers is the right fit, these Maryland counties currently have the most listed providers: Baltimore County (24), Dorchester County (22), Howard County (22), Montgomery County (22). Many providers travel or offer telehealth, so it is worth calling even if they are not based nearby. You can also tell us about a provider we are missing.
