While growing up in Chicago and Houston, her love for art, music and creative writing was influenced by her teachers and parents. She was once concertmaster of the Clear Lake High School Orchestra and a four-time violinist of the Texas All-State Symphony. A graduate of the University of Chicago, Catherine majored in English literature. Throughout her college years, she hosted classical programs on the campus station WHPK 88.5 FM, serving Hyde Park and south-side Chicago. Returning to Houston in 1999, she joined KRTS 92.1 FM as one of their chief announcers. She was the host of Midnight 'Til Dawn and also the producer and host of Seabrook Journal, a public affairs program, until the station closed in Fall 2004.
In her spare time, Catherine likes practicing violin, reading poetry, running and playing with her cats.
