About

Since the mid-1980s, The Gary Law Group has successfully represented businesses from around the country that have faced fenestration claims, window and door defect claims, window and door performance claims, AAMA claims, and other manufacturer and product liability claims.

Our business is devoted to the Recognition, Response and Resolution of legal risks and issues arising from the design, sale and performance of windows and doors. The problems faced by fenestration manufacturers and re-sellers are common nationally which allows us to provide effective service to companies and their local attorneys throughout the U.S. and into Canada. Our attorneys collectively bring over 60 years of experience with the matters that are important to you. 

Before fenestration became our exclusive endeavor, an omen was presented.  Thousands of miles from home, a Medieval Age guild hall revealed the stone relief shown on this page which honored the craft of making windows.  The course was then set and today continues to be travelled.

Matthew A. Johnson

Matthew A. Johnson devotes his practice to advising product manufacturers. Matt’s practice involves strategic consultation with executive level management concerning the spectrum of legal concerns impacting companies, including formation, acquisitions, documentation, claims, and compliance. A practice concentration with glazing and fenestration means that Matt’s experience with the variety of issues affecting all participants in these industries allows a broad and strategic perspective for realizing less-than-obvious opportunities.  Matt is a regular contributor to Glass Magazine, Window and Door, and a presenter at GlassBuild and other industry trade associations where he offers insights and advice to the industry.  Mr. Johnson is well suited to address the manufacturer’s legal and consulting needs in the increasingly sophisticated marketplace.

Susan MacKay

Susan MacKay joined the Gary Law Group in 2004. Her practice initially concentrated on product liability and construction law, including the oversight of litigation across the country. In recent years, Susan’s focus has shifted towards more transactional work, such as writing warranties and contract negotiations. She has a keen understanding of window and door issues and enjoys using that knowledge to draft effective and concise documents. Susan is a member of the Oregon State Bar and the Washington State Bar and publishes several blogs and articles in Window + Door each year.
