I am entering my 10th year as a member of the Payton counseling team. Prior to Payton, I spent four years in student services at the Northwestern University School of Continuing Studies and two years working for the NCAA Clearinghouse (now the NCAA Eligibility Center). I hold a BA from the University of Iowa and an MEd from DePaul University. I am a member of the National Association of College Admissions Counseling and have served on undergraduate admission, counselor advisory boards for the University of Chicago, Miami University in Ohio, and the University of Illinois at Urbana-Champaign.

I have worked for Chicago Public Schools for 24 years, first as a Social Worker in elementary schools and then as a Counselor. I received my Bachelors degree in English from University of Chicago and my Masters in Social Work from the Jane Addams College of Social Work at University of Illinois in Chicago. I completed my School Counseling certification at DePaul. What I love the most about my job is that no two weeks are ever the same! Outside of being a school counselor, I enjoy spending quality time with my family, movies, reading and writing.

I earned my Bachelors from The University of Michigan, and my Masters in School Counseling from Eastern Michigan University. During my undergraduate studies, I majored in Psychology and African American Studies and was also a member of the Track & Field team, where I threw the shot put, hammer, and weight. As an undergraduate, I also began mentoring at local high schools, which is where I developed my passion for education and decided to pursue my career in counseling. As a graduate student, I participated in many local school counseling organizations, specifically the Michigan School Counseling Association, where I volunteered for various events such as statewide conferences.

School counseling is a challenging, rewarding and fascinating profession and I couldn't be happier to be part of Payton's counseling team. Previously I was a founding faculty member of a successful north side charter school. Prior to my counseling work, I thoroughly enjoyed a career as a journalist, working for newspapers and magazines across the country. I specialized in covering urban education. During my professional transition, I also worked as a college admission counselor. My educational background: bachelor's degree in journalism from Boston University; a master's degree in Latin American and Iberian Studies from the University of Wisconsin-Madison; and a master's degree in School Counseling from Northeastern Illinois University. I truly enjoy helping high school students make the jump to young adulthood, navigate the world of college and start purposeful lives. I'm also pleased to serve students and families in English and Spanish.
