Kirsten Masrelian
Founder and CEO

Hello! I am Kirsten Masrelian, a state licensed Board Certified Behavior Analyst, or BCBA for short. I graduated with a undergraduate degree from the University of Wisconsin - Eau Claire in Behavior Analysis in 2012. During my time spent at Eau Claire, I spent three semesters working at the on campus Autism Treatment program, known commonly as CAP. After college, I moved to Florida where I continued my work in the field, becoming a Board Certified Assistant Behavior Analyst, or BCaBA for short. After some time I moved back home, and continued working in the field in the Fox Valley. I finished my Master's degree in Behavior Analysis in September 2017, and officially became a BCBA in December of the same year. I opened Milestone's because I recognized the lack of center-based services in the area, especially in my home town of De Pere. This is to bring much needed services, acceptance and awareness to the community I love.

I have also become the scheduling extraordinaire over the past few years as well.  Recently graduated from my Human Resources program in December of 2019 . My favorite thing about this job is the big impact we get to make - every day brings a new opportunity!
