After receiving her B.S. in Interior Design from Purdue University, Hannah and her husband moved to Maryland and she continued working in the design field.

She loves creating relationships with her clients, and considers it a privilege to design spaces that improves how they & their families live, work, and play.

Annamarie holds a Bachelor’s of Science degree in Mathematics from Mount Saint Mary’s University, and joined the Cornerstone design team in 2022. Clients love her attention to detail and calm, focused approach. Annamarie’s favorite part of her job is giving clients new ideas that they may not have thought of before for their spaces, and finding unique solutions to design dilemmas. Ever since she can remember, design has heavily influenced her life. She nurtures her artistic side by drawing, painting, and designing in her own home. When Annamarie is not here in the office, she is home juggling a busy life with her four kids and husband (and most likely wallpapering a room somewhere 🙂).

Molly has found that being a designer allows her to be creative while also doing something incredibly important to her - contributing to others' happiness!
