Meet the Osbourn Park Administrative Team!

I am delighted to serve as principal of Osbourn Park High School. I am both honored and humbled to work with this outstanding team in continuing the tradition of excellence at our school. Before arriving at Osbourn Park I served for five years as an assistant principal at Gar-Field High School, where I had the opportunity to supervise special education, science, and mathematics. I also provided support to grow and retain new teachers through my role as supervisor of the mentoring program. Of all the work accomplished at Gar-Field High School, I am most proud of developing positive and supportive relationships with teachers, and working to minimize barriers to effective instruction.
Prior to administration, I taught chemistry at both Potomac and Forest Park High Schools. I received a bachelor's and master's degree in food science from the University of Florida (Go Gators!), and a certificate in advance graduate studies in the area of education leadership from the University of New England. I am also very passionate about science, previously working in the citrus industry as a food scientist.
On a personal note, my greatest honor has been being a mom to my three children. I love traveling and spending time with my family. I am an avid reader, and enjoy reading science fiction, but I will never turn away from a great book on teaching or student learning!
Helen Keller once said, "Alone we can do so little; together we can do so much." As we move forward together, my guiding principle will be that all students can learn at high levels. It is through continuous pursuit and daily execution of this vision that we, together, will build upon tradition and reach even greater levels of achievement in the future at Osbourn Park. You can expect that I will work diligently to support our teachers to ensure our students continue to receive an outstanding education.
