Stephanie joined Arium in May 2000 with a strong background in commercial and institutional projects.
As an architect with more than 20 years of architectural design experience, she manages and designs a range of projects including commercial office and retail space, SCIF, healthcare, and educational. Stephanie also takes a lead position in the new employee training programs and developing and maintaining the firm’s technical and CAD standards.
Her approach to design is to listen to her client’s needs and then incorporate that vision into a cohesive design scheme. She especially enjoys the challenge that adaptive reuse brings: taking an empty office or warehouse and transforming it to a charter school, or renovating the abandoned big box retail building to be a new multi-tenanted town center.
Out of the office, Stephanie juggles a busy family life with her husband, and three children who are active in school and sports. And while Pittsburgh will always be her “home town,” living in Maryland is a return to her family’s roots.
