The start of TTR Engineers begins with Ernie Troike. He began his practice in 1963 working as a private consultant in civil and structural engineering. He brought a wide range of experience and expertise in everything from multi-storied hotels and offices, to water treatment facilities and towers. In 1996, Ernie sold his business to Brian Rostedt forming Troike-Rostedt Engineering, Inc. The newly formed partnership continued providing structural engineering consulting services to architects, builders and residential owners.

Following six successful years of service and a growing client base, the company opened another chapter when Larry Teeling agreed to join Ernie and Brian.  They formed Troike-Teeling-Rostedt Engineers in 2004. Having already spent forty-three years in the field, Larry had established himself as a skilled and respected consultant for a variety of projects. These include structural seismic upgrades, adaptive re-use and rehabilitation of existing structures, the design of commercial and institutional buildings and bulk material handling systems. 

In 2006, the company shortened its name to TTR Engineers. Moving forward our goal is simple: to provide you with the best in structural engineering. With our experience, our professional engineers and engineering designers bring dedication, professionalism and excellence to every project.  Whether your project is residential, commercial or industrial in nature, our diverse history and expertise in structural engineering can meet your structural engineering requirements.
