ABA Therapy at Riverside Behavioral Health

Tina Sullivan, BCBA | Drew Haverstock, PT
Drew left the Fortune 500 business world in 1997 to return to school and pursue his dream of becoming a Physical Therapist. He did this two weeks before getting married, which went over great with his Father-in-Law to be.
While he thought that he'd wind up working in sports or outpatient orthopedics during his education at UIC, he fell in love working with children somewhere along the way. After a series of pediatric jobs in Illinois EI and at local hospitals – all that ended miserably through employer bankruptcy or buyout -- Drew decided to start his own company, Milestone Therapy, in 2002 following the George Costanza mindset of doing “exactly the opposite.”
Initially doing solely Early Intervention on his own, Drew has grown Milestone to include all major pediatric disciplines for EI and is in over 25 different school districts throughout the Chicago-land area and northwest Indiana. The heart of the company resides at their facility located in downtown Highland, IN, just across the state line from Chicago. At over 12,000 square feet of pediatric rompin' stompin' dynamite, as well as housing all MST’s back-office efforts, it’s the epitome of what they envision all our clinics to be. Since then, Milestone has opened a second clinic in Merrillville, Indiana and forged strategic partnerships to create and run pediatric clinics with both the Franciscan Healthcare system in Olympia Fields as well as Riverside Hospital system in Kankakee, IL. With the addition of ABA services in 2017, Milestone has secured their status as THE place for pediatric therapy services throughout the southwest suburbs of Chicago and northwest Indiana.
While the business end of things can be time consuming, Drew found by giving up sleep for Lent in 2003 and never picking it back up, he can do everything he enjoys. From coaching softball and flag-football, to reading Spider-Man, to traveling the world, he keeps himself ridiculously busy with his wife Elizabeth and their three kids.
Through it all, Drew's passion still lies with treating children on a day-to-day basis. Simply put, “Helping a kid learn how to walk makes it easy to get out of bed every morning.”
