Three ABA providers have a physical office in Greeley. Most companies that appear when you search for ABA therapy in Greeley do not. They serve the city from Denver, Fort Collins, or another state entirely, and they come to your home instead. Neither model is better. But the difference changes who drives to your house, how far a supervisor travels to watch a therapy session, and how fast someone can cover when your therapist calls in sick. Almost no provider page explains it, so this guide does. Applied behavior analysis, shortened to ABA, teaches skills in small steps and builds on what works. For a child with autism spectrum disorder that usually means communication, social interaction, daily living skills and calmer daily routines. A board certified behavior analyst writes the therapy plan. A trained therapist runs the sessions.
How this comparison was built
Every provider below was checked against its own website in August 2026. Addresses, ages and insurance details come from the company itself, not from a directory. Two rules kept the list honest. Providers whose only published address sits outside Colorado were left out. And where a company does not publish a detail, the table says so rather than guessing. That second rule matters more than it sounds. Several pages ranking for this search advertise centers in Greeley without listing a single address. Check the address and the insurance page yourself before you call. This is not a ranking. The table groups providers who come to your home first, then the centers with a Greeley address, because that is the choice most families make before any other one.

The three ABA therapy providers with a Greeley office
Action Behavior Centers
A center-based clinic at 5400 W 11th St, serving children from 18 months to 8 years. Its model is a clinic day rather than home visits, with an academy program that bridges children toward school age.
Consultants for Children
At 1610 29th Ave Place, this practice pairs ABA with counseling services, which is unusual locally. Its site states that it accepts most major insurance plans including Medicaid in Colorado. It does not currently appear in the state's published behavioral therapy provider list, so confirm that directly before you rely on it.
Center for Autism and Related Disorders
CARD works at 1675 18th Ave and offers both center and home sessions. It runs named parent-training and school-readiness curricula, and its site says it has no waitlist for ABA services.
In-home ABA therapy providers who come to you
In-home providers cover Greeley from elsewhere on the Front Range. Their advantage is that skills get taught where your child actually needs them, at your kitchen table and during your real bedtime routine. Each builds an individualized treatment plan from an assessment, then works on the goals that matter most to your family. That might be social skills, toilet training, or challenging behaviors that make mornings hard. Caregivers are trained alongside the child, because most of the week happens when no therapist is present.
Budding Futures ABA
Works in homes and inside schools across Colorado, for ages 18 months to 18 years. Plans are reviewed by a named clinical director, Rachel Blackburn, BCBA, rather than an anonymous care team. It accepts Health First Colorado along with Aetna and Anthem Blue Cross Blue Shield, uses the VB-MAPP and ABLLS-R assessments, and reports no waitlist. School access still depends on each district agreeing, which no provider can promise.
Achieving Stars Therapy
An in-home practice serving ages 18 months to 15 years, built around a play-based approach it calls Connection over Control. It schedules between 8am and 8pm, including evenings, and accepts Medicaid in every state it serves plus most commercial plans. Most families start within one to two weeks on private insurance, though Medicaid takes longer because of prior authorization.
Cedar Grove ABA
An in-home provider based in Denver that lists Greeley in its service area. It describes a focus on older children and severe behaviors, a group many providers turn away.
New Dawn ABA, Key Autism Services, Green Light ABA and Treetop ABA
All four serve Greeley from outside the city. New Dawn names Natural Environment Teaching and play therapy and works up to age 18. Key Autism Services says it starts as early as 6 months. Green Light and Treetop both describe in-home models. None publishes a Greeley street address.
The supervision question Greeley parents should ask
Colorado is short on the people who supervise ABA, and the numbers show it. The Behavior Analyst Certification Board's certificant dashboard lists 8,242 Registered Behavior Technicians in Colorado against 1,901 board-certified analysts. That is roughly 4.3 technicians for every analyst. Nationally the figure is about 3.4. Registered behavior technicians, or RBTs, run the sessions. BCBAs write the therapy plan, track progress toward each milestone, and check that the approach is still evidence-based and still working. When the ratio stretches, supervision is the thing that gets thin. Practice guidelines from the Council of Autism Service Providers put the standard of care at two hours of case supervision for every ten hours of direct therapy. So ask any provider a plain question: how many hours a week will a board-certified analyst spend on my child's case, and how much of that is watching a live session? A provider that answers with a number is telling you something. One that answers with a philosophy is not.
Autism in Greeley-Evans School District 6
Demand in Greeley has grown fast. The Colorado Department of Education counts students by disability category each December.
Provider details at a glance
2020 to 2021. Students in the autism category, District 6: 172.
2022 to 2023. Students in the autism category, District 6: 233.
2024 to 2025. Students in the autism category, District 6: 307.
That is close to double in five years. Statewide, Colorado identified 13,837 students under the autism category in 2025 to 2026, about 12 percent of all students receiving special education. Worth knowing: Colorado has no current autism prevalence figure of its own. The state left the CDC's monitoring network in 2018. Any "Colorado autism rate" you read is either national data relabelled or roughly a decade old. The current national figure is 1 in 31 eight-year-olds, from 2022 surveillance across 16 sites, none of them Colorado.
What Colorado actually pays for
Two things about coverage are widely repeated and wrong. ABA is not capped at age 21 by Colorado law. The autism section of Colorado's insurance statute contains no age limit at all. The "through age 21" figure comes from the older version of the law, before 2015 changes removed the caps, and it still circulates on provider pages and directories. Health First Colorado does not require an autism diagnosis. The state's own guidance answers this directly: a child does not need an autism diagnosis to qualify for behavioral therapy. Autism is one qualifying condition among several. Coverage runs through age 20 under the federal EPSDT rule, and every course of treatment needs prior authorization before it starts. Self-funded employer plans are a separate story. They fall under federal law rather than Colorado's insurance rules, so the state mandate does not reach them. Ask your employer's benefits administrator which kind of plan you have.
How to start ABA therapy in Greeley
Under 3. Early intervention for Weld County runs through Envision, at 1050 37th Street in Evans, on (970) 339-5360. You can also use Colorado's statewide referral line, which is now 833-733-3734. An older number, 1-888-777-4041, still appears on many sites. Age 3 and older. Greeley-Evans School District 6 handles Child Find, the free screening and evaluation process for preschool and school-age children. Reach the preschool team on 970-348-1050. You do not need a diagnosis to ask for a screening. School services and private ABA can run at the same time. Many families use both.
Questions Greeley parents ask
Is ABA therapy just for autism?
No. Health First Colorado covers behavioral therapy for any medically necessary condition where it is clinically appropriate, and autism is listed as one example rather than the requirement. Private plans differ, so check yours.
Is Colorado a good state for autism services?
Mixed. Waitlists here are shorter than in many states, and several Greeley-area providers say they are accepting families now. But Colorado runs leaner on board-certified supervisors than the national average, and the state publishes no prevalence data of its own.
How much does an hour of ABA therapy cost?
It depends almost entirely on your plan, not on the provider's rate. With Medicaid or solid commercial coverage many Colorado families pay little or nothing out of pocket. Ask each provider to verify your benefits in writing before the first session.
What are the disadvantages of ABA?
Worth taking seriously. Many autistic adults describe ABA, especially older and more compliance-focused versions of it, as harmful. Modern practice is meant to look different: following the child's lead, treating distress as communication rather than defiance, and stopping when a child withdraws their agreement. Ask a provider directly how they handle a child who refuses, and listen closely to the answer.
How do I know a supervisor is really involved?
Ask for the weekly number of analyst hours on your child's case, and ask how many are spent observing live sessions. Compare it to the two-per-ten guideline above.
