    Rod
    Production Manager
    Rod has been with GreatHouse for 14 years, but his experience runs deep: 5 years of framing houses, 7 years doing custom millwork, 4 years building townhouses, spec houses, and property development, 2 years of high-end remodeling, and 12 years running his own remodeling company. (If you do the math, it looks like Rod began remodeling when he was 10, but he was very mature for his age.)
    Abbey
    Preconstruction Manager
    Abbey comes to GreatHouse with nearly 10 years of experience in strategy consulting, small business growth, and design build remodeling. Abbey received a Bachelor’s degree in Finance from William & Mary and an MBA from the Kellogg School of Management at Northwestern University. Abbey grew up in a remodeling family and has been in and around the business her whole life. In her free time, Abbey and her husband can be found in a tent on a mountain pass somewhere extremely remote (so really, maybe she can’t be “found” there).

    Administration

    Christina
    Office Manager
    Christina has been working as an office administrator for over 12 years, but got her start in the hospitality industry after earning a degree in the culinary arts. Born in Georgia, she grew up in Kennesaw and currently lives in East Cobb with her husband, Brent and teenage son, Patton. As a family, their favorite activity is riding roller coasters and have been doing their best to check off coasters around the country on their "roller coaster bucket list.

Linnea started her career in commercial architecture, working on a wide range of projects including office buildings, hotels, and even a ballpark. In 2010, she returned to her roots in residential design and remodeling, where she discovered her true calling. Today, Linnea is dedicated to helping homeowners create spaces that feel both beautiful and livable—true havens tailored to each family’s needs and lifestyle. When she’s not reimagining floor plans or selecting finishes, Linnea enjoys visiting her family in Hawaii, where you’ll likely find her hiking, paddle boarding, relaxing on the beach with a good book, or enjoying fresh sushi.
