The W Group Commercial Real Estate (WGC) was established in 1991 by Kwang Chul "KC" Whang, its founder and principal broker.  WGC evolved into a full service, cross-cultural, multi-lingual business consulting firm that specializes in assisting small and large businesses operating around the nation's capital, with issues ranging from: real estate, tax and accounting, human resource management, facilities management, property management, to product sourcing and marketing. 

For over three decades, WGC has consulted for and brokered a wide range of businesses: restaurants,  liquor stores, dry cleaners, day care centers, electronics stores, print shops, martial arts schools, laundromats, hotels, convenience stores, supermarkets, fashion boutiques, mini storages, automotive businesses, among others, including independent, national and regional chains and franchises.

An area of niche specialty for WGC is church real estate.  WGC has assisted numerous churches in the Washington-Baltimore region in the leasing, acquisition and development of church facilities.

WGC has successfully worked with a full spectrum of real estate products ranging from raw land to custom-built spec buildings; from residential, office, retail, to industrial.
