Meet Liz

I’m Liz Cahill, a Board Certified Behavior Analyst, Certified Behavioral Sleep Specialist, and former special education teacher. I founded BetterSleep because I know how exhausting and overwhelming it can feel when your child struggles with sleep—especially when you’ve tried everything and nothing seems to stick.

Sleep touches every part of family life—behavior, learning, emotional regulation, and the overall well-being of both kids and parents. I take a compassionate, science-informed approach to create personalized sleep plans that actually work in real homes with real kids (and really tired parents).

Whether you’re navigating sleep challenges with a child on the autism spectrum or simply need support that truly understands your family’s needs, you’re in the right place.

I offer three levels of sleep support—from quick strategy sessions to ongoing coaching—so you can choose the level of guidance that works best for you right now. Together, we’ll build a plan you feel confident using—so bedtime can finally feel calmer, smoother, and more restful for everyone.
