One of a handful of autism centers in Colorado, Firefly offers one of the most comprehensive services in the country. Our services include clinical assessments and the development of individual treatment plans, an intensive early intervention program, a school-age program for students up to age 21, a home and community based program, and weekly social skills groups. Firefly serves children (as young as 18 months of age) and adults, and every program in our clinic has a 1:1 student to teacher ratio. Firefly’s treatment is based on leading, empirically based interventions, primarily using Applied Behavior Analysis (ABA) to teach functional skills. The supervising personnel for ABA-based programs are Board Certified Behavior Analysts (BCBAs) who, in addition to holding a graduate degree, completing a series of coursework in ABA, required hours of supervision, and are credentialed by the Behavior Analysis Certification Board (www.BACB.com). To maintain certification, each analyst must maintain continuing education at least annually. To enhance service delivery, our organization includes speech and occupational therapy, and mental health services, based on the individual’s needs.
