Hello! I am excited to join the EL department here at Potomac Falls High School. Originally from Texas, I earned my Bachelor's in Communication Arts and my Master's in Teaching Secondary Education from Austin College in Sherman, TX. I taught high school theatre and speech before moving to Virginia. I am finishing my graduate certificate in Teaching English to Speakers of Other Languages (TESOL) with George Mason University. This is my seventh year with LCPS.
