De La Torre


Originally from Monterrey, Mexico, Kathia has always had a passion for art and design ever since she was a young girl. This passion then grew into pursuing a career where her dreams of designing modern interiors and custom furniture would become a reality. After becoming an intern for a hospitality firm during her college years, she was set on working in the commercial field, but that mentality soon changed once she graduated. Upon receiving a Bachelor’s in Interior Design from Baylor University, she soon became a member of Slovack-Bass. This great opportunity has led her to develop a passion for residential design and to continue doing what she loves most, 3-D modeling and rendering. Kathia has lived in Houston for most of her life, and when not at work, she spends her free time cheering on her favorite sports teams and going to concerts to further enjoy her love for music.

In June of 2017 she joyfully joined the Slovack-Bass team.  A Houston native, Cali continues to call northwest Houston her home.  When not designing, she enjoys time in the company of her fiancé, family, friends, and dogs.
