Hello Cabin John Middle School community! This is my third year at CJMS and I am excited to be a part of such a wonderful community. I am a Montgomery County product through and through. I was born, raised and graduated in MCPS. This will be my 16th year as an educator in MCPS. Prior to my current position, I was a P.E. and Health teacher, 8th and 6th grade team leader, Restorative Justice Coordinator and Assistant School Administrator. I have a passion for relationship building and equity in education. A little bit about my personal life, I am happily married with 2 young children and love any and all sports! I am proud to be a Cabin John cougar and serve this community of learners. Looking forward to another great school year!

Greetings Cabin John Middle School community! This school year will be my second year as a Cabin John Cougar, and I feel incredibly privileged to serve this community and our students and families. I am originally from a small town outside of Scranton, Pennsylvania, and after graduating from Kutztown University of Pennsylvania, I moved to Montgomery County to teach social studies at Sligo Middle School. This will be my 15th year as an educator in MCPS. Prior to serving as an assistant principal here at CJMS, I was the Academy Coordinator and Theory of Knowledge teacher at John F. Kennedy High School; a Consultant Teacher in the Office of Human Resources and Development; Project SUCCESS Teacher at Argyle Magnet Middle School (AMMS); social studies Content Specialist and team leader at AMMS; and prior to that served as a social studies teacher at Sligo Middle School to start my career in MCPS. My core values are empathy and integrity: with these values in mind, I strongly believe in our school’s goal in helping our students be their most respectful selves, build positive interpersonal relationships, and support their resilience to bounce back from challenges. My wife and I live in Wheaton, Maryland, and we have one wonderful daughter who is going to be three very soon! I am super excited for this school year!
