Interior Designer

Who is Hartzog Interiors?

Hartzog Interiors, LLC was established in 2009. Owner and designer Katie Hartzog founded the company after obtaining a degree in interior design and working under a custom design studio for several years. Her extensive experience and rich knowledge of all aspects of interior design quickly grew Hartzog Interiors into a regional leader in the industry.

In 2014, the firm expanded as Katie’s husband, Mark Hartzog, sold his business to join forces in managing the burgeoning workload. This new partnership, greatly augmenting the company's creative capacity, enabled the duo to offer unprecedented quality in full-service home design like none in the region. Business was booming.

Today, Hartzog Interiors retains its status as head of the pack by bringing clients the absolute best in custom design for their interiors. Every facet of building new, custom homes, remodeling existing homes, and providing furnishings, window treatments, and the smallest finishing details comes as a standard feature in the Hartzog Interiors palette of expertise.

Hartzog Interiors is also actively involved in the local community and is a proud donor to local charities. As a token of gratitude, Hartzog Interiors contributes to the historical Embassy Theatre, Habitat For Humanity, and Mustard Seed Furniture Bank. Giving back to both her clients and community is a remarkable source of inspiration for Katie and her company.
