Catherine Martone, the firm’s principal partner, is a licensed architect and an AARP certified aging-in-place specialist. She received a Bachelor of Science in Architecture degree from Catholic University and a Masters of Architecture from the University of Pennsylvania. For over 20 years she worked with Hall Partnership Architects in NYC as a project manager and project architect. She became the go-to person in the office when questions arose about handicap accessibility and ADA compliance. After helping her mother and uncle make changes to their homes to accommodate their more limited abilities, Catherine realized others had this same need and decided to become a certified aging-in-place specialist—a joint certification from AARP and the National Association of Home Builders (NAHB). With her partner, David Hallerman, they opened their firm, In Place ReDesign Architecture dpc, which specializes in aging-in-place. She offers design, analysis and consulting to help people determine what home modifications can make their lives easier, safer and more independent. Her services allow her clients to remain in their homes and communities as they age.
