Your Guide to Autism Resources in Longmont, Colorado

Longmont has more autism support than most Colorado cities its size, but it's scattered across county programs, school offices, nonprofits, and private providers. This guide pulls it into one place: who to call first, which providers actually serve Longmont (with addresses and phones), how school services work in the St. Vrain Valley district, and how families pay for it all.

Key Takeaways

• Start with two local anchors: The Boulder County Children with Special Needs Program in Longmont at 303-678-6064, and the Autism Society of Boulder County directory, which keeps a Longmont-specific resource list.
• Three ABA options sit in town: Action Behavior Centers, Behavioral Innovations, and Lacuna Autism Services, plus school and county programs that cost nothing.
• Two funding paths cover most families: Colorado's insurance mandate (SB 09-244) and Health First Colorado (Medicaid) are the main ways families pay for therapy.
• Start ABA without a waitlist: Match with an in-network BCBA through Alpaca Health for in-home or telehealth care covered by Medicaid and 100+ plans.

Where to Start in Longmont: A 5-Step Plan

1. Call the Boulder County Children with Special Needs Program. The office sits at 515 Coffman St in Longmont, 303-678-6064, open weekdays 8 to 4:30. Coordinators connect families to evaluations, funding, and local programs.
2. Browse the Autism Society of Boulder County's Longmont directory. Their Longmont resource list is the best-maintained local index: therapy providers, adult services, recreation, and support groups, filterable by category.
3. Request a school evaluation. Longmont sits in the St. Vrain Valley School District. Put your request in writing to your school and the SVVSD special education department (district line 303-776-6200). Evaluations and IEP services are free.
4. Sort funding. Check Health First Colorado eligibility and your private plan's obligations under Colorado's autism mandate (details below).
5. Pick a therapy provider. The verified Longmont options are in the table below.

School Support Through St. Vrain Valley Schools

SVVSD must evaluate any student suspected of having an educational disability and provide services through an IEP at no cost. Two things speed this up: request the evaluation in writing (timelines start when the district receives it), and bring any outside evaluations you have, since the district considers but doesn't require them.

If your child needs accommodations rather than specialized instruction, ask about a 504 plan instead; our Colorado 504 guide covers when each fits. Child Find, the district's obligation to identify children with delays from birth through age 21, also covers free preschool-age evaluations.

Paying for Autism Services in Longmont

Health First Colorado (Medicaid). Colorado's Medicaid program covers medically necessary pediatric behavioral therapies, including ABA, for eligible children. Start at healthfirstcolorado.gov and cross-check providers on the state's official provider list. Our guide to Medicaid ABA coverage explains eligibility and prior authorization.

Private insurance. Colorado's autism insurance mandate (Senate Bill 09-244) requires many state-regulated health plans to cover autism diagnosis and treatment, including ABA. Self-funded employer plans follow federal rules, so ask your insurer for your ABA benefits in writing before assuming either way.

Grants and gap funding. For costs insurance won't cover, from copays to sensory equipment to camps, start with our roundup of Colorado autism grants. Imagine!, the area's developmental disability nonprofit, is also the local gateway to waiver services and family support funding.

Support for Teens and Adults

Support doesn't end at graduation, but the doors change. DVR handles employment and job training for adults with disabilities, Imagine! manages adult waiver services for the Boulder area, and ACL advocates on housing, benefits, and guardianship questions. The Autism Society of Boulder County's directory also has a dedicated adult services category for the Longmont area.

If your teen is within a few years of leaving school, ask SVVSD to build transition goals into the IEP now. That's what connects school services to DVR and adult supports.

Beyond Therapy: Recreation and Community

Longmont families have real recreation options, from adaptive programs through local rec centers to equine and animal-assisted programs in the surrounding area. The Autism Society of Boulder County's Longmont directory keeps the current list, and its family events are an easy, low-pressure way to meet other parents. For the statewide view, including Denver-area specialists and programs, see our Colorado autism resources guide; families near the Denver line can also compare Denver diagnosis options.

Frequently Asked Questions

Where should we start if our child was just diagnosed in Longmont?

Make two calls: the Boulder County Children with Special Needs Program (303-678-6064) for care coordination, and your child's school (or SVVSD special education if they're not yet enrolled) to request an evaluation in writing. Those two threads, county support and school services, run in parallel and neither should wait for the other.

What can our child get for free in Longmont?

School evaluations and IEP services through SVVSD, county care coordination through the Children with Special Needs Program, early intervention for children under 3 through Imagine!, and no-cost ADOS-2 autism evaluations for ages 18 months to 6 years through Action Behavior Centers' Longmont location, per their published program. Advocacy help from ACL is low-cost or free as well.

Does insurance really cover ABA therapy in Colorado?

In most cases, yes. Colorado's SB 09-244 mandate requires many state-regulated plans to cover autism diagnosis and treatment including ABA, and Health First Colorado covers medically necessary ABA for eligible children. The main exceptions are self-funded employer plans, which follow federal rules, so get your own ABA benefit confirmed in writing.

If the coverage is there but every in-network provider has a waitlist, Alpaca Health matches Longmont families with in-network BCBAs, usually within days. Start your match today.

What support exists for autistic adults in Longmont?

The Division of Vocational Rehabilitation covers employment and job training, Imagine! manages adult waiver services, ACL advocates on housing and benefits, and the Autism Society of Boulder County lists adult social groups and services for the Longmont area in its directory.
