Being a wife, mom, auntie and friend to those I love is the foundation of my drive and motivation. Since I was little, I’ve always had a nurturing tendency, but playing a role in someone’s growth, well-being or learning is pretty amazing.

I am motivated to work in this field because I want to offer a sense of hope to clients and their families during what is likely one of the most difficult times in their lives. A diagnosis of some sort frequently precedes behavioral health treatments such as ABA. Families are then often bombarded by medical appointments and referrals to additional specialists soon after that. Specialists, like me offer hope; however, this process is scary and overwhelming for parents. I realize this and also how much is at stake. I pride myself in being an empathetic, energetic, accessible and easy to work with behavior analyst that can offer the family hope; hope to one day witness their loved ones communicate effectively; hope to one day see their loved ones’ independence grow; hope to one day see their loved one engaged in socially meaningful interactions; and hope to one day not need us, or any other support for that matter.
