About Grace Allen Design

Heather Langhofer


Heather Langhofer

I’m Heather Langhofer, owner of Grace Allen Design. You may be wondering “Who is Grace Allen?” No one, actually, but our name does have meaning.

When I started this company I had only one daughter. Grace is her middle name, and Allen is my husband’s middle name. It was (and still is) a great company name because it is a reminder of what inspires me every day — my family.

And so a little about my journey…

As an OSU graduate with a degree in design, housing and merchandising, and I’ve spent my career in home interiors. Beginning in 2003 I began working exclusively with shutters, blinds & shades in my family’s business, Kirtz Shutters. This experience taught me that working with homeowners to identify and select the perfect window treatments for their needs is a process I LOVE.

After repeated requests for homeowners to help them with drapery, I started Grace Allen. In 2014 when our family expanded, my husband Drew stayed with Kirtz Shutters, but we decided the time was right for me to focus solely on Grace Allen Design.

The path since then has been amazing. It has been one of learning and growth both personally and professionally. I’m constantly refining and adjusting our process to make sure it is as low stress and effective  as possible for our clients as they create their unique home with our window treatment services.

After working in and around the interior design world for many years, I’ve enjoyed getting to focus on window treatments.  I love the way fabric can bring warmth to a room and be such a personal expression in a space.  Pulling together fabric and color palettes with clients for drapes, blinds and shades is my favorite part of the window treatment process!

We Value

Through my experience I’ve learned to value:


The importance of great communication and education when helping homeowners navigate the selection process. When working with custom products I CANNOT overstate the importance of great communication!


Representing and offering only quality products that my clients will enjoy for years to come. Value is the life experience with a product, not just the initial investment price. As a result, I align my company with the best manufacturers, workrooms and products available today.


The integrity and commitment to customer service before, during and after a client chooses me to help them.

“I’m passionate about the window treatment industry and quality products. I love helping people select amazing blinds, shutters, shades and draperies for their home. I look forward to serving you. So shoot me an email, or give me a call to schedule your consultation today!”
