Sabrina Bartels

Sabrina’s love of public speaking began at the age of 4, when she was asked to read a petition in front of her entire school. Spurred on by adrenaline and a fondness for talking, she continued to speak at school, eventually joining both the Debate and Forensics teams when she arrived at Greendale High School in 2003. Thanks to Sharon Sharko, Sabrina was able to develop more finesse and really hone her public speaking skills. Many of her favorite high school memories include Forensics State tournaments in Madison and spending time with her team between rounds.
Sabrina went to Marquette University for college, where she was a Burke Scholar and a member of Psi Chi, the International Honor Society in Psychology. Through the course of four years, she accrued over 1,000 hours of community service. She served as Vice President of the Marquette Chapter of the Big Brothers Big Sisters program, and worked as a tutor for the Educational Opportunity Program, focusing on high school mathematics and introduction to psychology. Sabrina graduated from Marquette in 2011 with Bachelor’s degrees in Broadcast and Electronic Communication, as well as Psychology. She stayed at Marquette to earn her Master’s degree in School Counseling in 2013, and began working as a counselor for the West Allis-West Milwaukee School District. Currently, she serves as the Tier 2 coach for the PBIS team at her school, and is co-advisor for the Harry Potter Club.

While on a cross-country trip to New York, Sharon kept my younger sister Lynda and I occupied in activities to better understand the history, geography, and people of the United States. Sharon’s travel and interest in politics nurtured within me a natural openness to new places, new people, and new ideas. Sharon introduced me to debate in my early-thirties. My involvement as a debate adjudicator for Greendale High School and a debate research resource was invaluable in my personal and professional development from a technical specialist to a global business advisor. I really miss Sharon’s humor, her critical thinking, her wisdom and her counsel.”
