Register-Nelson, Inc., is an environmentally oriented, non-engineering consulting firm specializing in Section 404 of the Clean Water Act stream/wetland permit and mitigation issues, endangered species identification and coordination, and coordinating on State stream law issues. We were founded by a former Corps of Engineers' biologist on the principles of providing environmentally practical solutions to problems associated with development.

Register & Associates opened in 1999 as a one person company. Mark Nelson then joined founder, Butch Register, in November 2001. Prior to opening Register & Associates, Register spent 11 years working with the U.S. Army Corps of Engineers and Environmental Protection Agency, where he met Nelson. Register-Nelson now boasts an 18 member staff of environmental scientists and business professionals, with more than 100 years of combined work experience. To underscore this growth and to reflect the team approach to successful environmental consulting services, the company's name has now officially changed to Register-Nelson, Inc., Environmental Consultants.

Our mission is to serve an expanding array of clients and industries by bridging the gap between land development interests and environmental interests. Through our long-term experience with environmental regulatory agencies such as U.S. Army Corps of Engineers (USACE), Environmental Protection Agency (EPA), Georgia Environmental Protection Division (GaEPD) and U.S. Fish and Wildlife Service (USFWS), we have developed procedures to guide our clients through the sometimes rigorous regulatory process. Keeping this process “turn-key” is our goal.
