Gene Riffle - Outside Sales

Gene Riffle, Outside Sales & Project Manager, has been with Lilienthal Insulation since 1997.  Starting in the field installing all types of insulation and acoustic ceilings, Gene has a vast knowledge of all aspects of the business.  His continued training keeps him knowledgeable in “whole building envelope theory” using new and improved methods to save energy, improve air quality, and best use of materials both in residential and commercial projects. 

In his spare time Gene, like many Montana natives, loves hunting, fishing, camping, and boating with his wife Layla and their two sons.  With lots of time spent at various school activities and volunteering at the local Elks and Moose Lodges, he knows just about everyone in the Flathead Valley.



Scott Larsen, Outside Sales

Scott Larsen, Outside Salesman, plus job scheduler and employee productivity facilitator, has been with Lilienthal Insulation since 1994. Scott is one of those guys that everyone likes, from the customer to the installer, he gets along with everyone. He is at the office at 6:00 every morning, filling out the work schedule, helping the guys load their trucks, and getting them off to their jobs. Then he is either out in the field meeting customers and giving estimates, or he is checking on ongoing jobs, or he is back at the office fielding phone calls and inquiries. As you can see, in his spare time, Scott enjoys hunting trophy whitetails. The one pictured is a record book buck, scoring 175 5/8th Boone and Crockett points. Give him a call for an insulation estimate, or some hunting pointers.



Dennis Sturm - Retail Sales

Dennis Sturm, Inside Salesman, has been at our front counter since 1989. People that know Dennis love him, people that don’t know him, should. He is extremely knowledgeable in all things roofing, and can answer your questions about style, durability, application and tool requirements. Dennis shows up at the office shortly after 5:00 A.M. and is bright eyed and ready for that first customer. When not working, Dennis enjoys fishing, bow-hunting and raising his by now famous organic garden products. Call Dennis anytime with questions you may have concerning roofing, drywall or insulation.
