Jang Yoon
Single Family Practice Lead

Jang Yoon was destined to be building scientist, an epiphany he has only recently realized.  A son of a civil engineer, his life revolved around buildings and structures before he could walk, and showed an early interest in how things are designed and constructed.  His interests led him on a varied path that covers antique Oriental rug restoration to manufacturing minimally invasive medical devices.  The common thread that ties his eclectic history is his love of aesthetics in relation to function.  He holds an engineering degree from Boston University, is a RESNET Certified HERS Rater, and an ICC Residential Energy Inspector/Plans Examiner.
