CORE TEAM
Lisa Tharp
FOUNDER + PRINCIPAL DESIGNER
Lisa has been an enthusiastic student of architecture and design since childhood. She founded Lisa Tharp Design in 2011 after a fulfilling career in other visual arts forms (HBO, Time Life Video & Television). She has built a team that shares her belief in good design’s power while offering wonderfully diverse points of view. Lisa has kept the firm intentionally small in order to stay close to the creative process. Her MBA training and corporate experience ensure clients enjoy a well managed project.
Lisa was inducted into the New England Design Hall of Fame in 2021. She is also a member of the Institute of Classical Architecture & Art and the Back Bay Architectural Committee. She enjoys spending time with family and friends, traveling, painting, and inline skating.
Alex MacMillan
SENIOR DESIGNER
Alex collaborates closely with Lisa in leading creative development across the firm’s design projects and media content. Her Masters of Interior Architecture training enables her to digitally visualize and specify our concepts for clients and industry partners alike. Alex’s passion for design and remodeling started at a young age, watching her parents renovate over ten historic Maine properties. When not designing, Alex can usually be found somewhere outdoors, at a concert or hosting a dinner party.
Sienna MacArthur
JUNIOR DESIGNER
Sienna brings organization and attention to detail to our creative development and implementation processes. With a French-American education, Sienna split her childhood between her family’s maple sugaring farm in upstate New York and Southern France. Her open-minded and unique approach to every design project stem from her international background and degree in art history. As a yoga teacher in her free time, Sienna’s passion for wellness and sustainability help inform her human-centered perspective to design. She is currently pursuing a Masters in Design for Human Health.

Elizabeth Santin
DESIGN ASSISTANT
After trying out an interior design internship, Elizabeth committed fully to a career pivot. Undaunted by a global pandemic, she moved to Florence, Italy to earn her master’s degree while immersing herself in regional culture. To our work, she brings her design skills, creativity, and dedication to sustainability, wellness, and local sourcing. When not hiking or skiing, Elizabeth can be found painting, sketching, antiquing, or cultivating an organic garden. An avid dog lover, she cannot pass one without giving them a friendly pet.
