"Marc did a great job on our garage expansion project! He was friendly and professional, taking all of our ideas and criteria and combining them into a great layout. The drawings themselves look great. We are still shopping the plans around to contractors, and Marc is always helpful with advice or ways to reduce cost. Would definitely recommend him to anyone looking for an architect."

"Architect Kristin Kollias has provided me with professional and responsive help in the renovation of a vacant single family bungalow in Chicago that required extensive repair for compliance with the City of Chicago codes. She assisted in guiding me in obtaining required site plan for the residence; addressed the structural, electrical and plumbing details required; drafted and created the architectural floor plans that fit my vison of interior space; and facilitated in obtaining the necessary city permits from City of Chicago. Clearly she is a true professional and her services are greatly appreciated."
