Steve’s GIS career spans 20 years mostly with the Southeast Michigan Council of Governments (SEMCOG) and with Wayne County, MI. During his time with SEMCOG, he initiated the first ever multi agency regional orthophotography flight in Michigan covering over 5,000 square miles. While as the GIS Technical Manager at Wayne County, Steve oversaw the road network conflation initive as well as the conversion of over 800,000 parcels to the County GIS parcel fabric. However, the passion Steve has with GIS is how it can be adapted to so many disciplines to answer questions and build collaborative relationships. Six years ago Steve and his family moved to Connecticut for his wife’s job. While being a stay at home dad he volunteered his GIS services to the Granby Land Trust and just recently formed his own consulting company. Steve received his Bachelor of Science in Forestry from Michigan Technological University and his Masters in Geography/GIS from Eastern Michigan University. He is also a GISP.
