Brenda Melhem

Brenda Melhem, MA, BCBA, Clinical Supervisor

I started developing a unique skill set necessary to become a high caliber therapist when my brother was diagnosed with autism in 2008. Since that day, my brother became my motivation to move forward and I devoted all my time and effort to becoming a remarkable behavioral interventionist. I promised to stand, not only by my brother, but also with all children in need and nurture them; this became my main goal. I have faith that every single child, regardless of what their situation is, when helped and given a hand, will reach even further than we ever thought possible; the sky is the limit. My journey as an Applied Behavior Analysis (ABA) interventionist started in 2014 and since then it has added various skills and knowledge to my training path.

In April 2017, I started pursuing my master’s degree in Applied Behavioural Analysis and received my BCBA Certification on September 20th. My journey at Clinique Spectrum started on November 2nd, 2017, where I started offering behavioral analytic services to clients with special needs. It has been an amazing and particular experience to be part of a highly specialized interdisciplinary team, all of whom specialize in the care of autism and other neurodevelopmental disorders. My objective is to continue to serve children with developmental disabilities and help them achieve long-term goals. I am always looking forward to bringing my personal and clinical experience into the ABA field.
