Building Homes or Extensions/Expert Profile

Ask A Question


I can answer questions concerning log home design, manufacture, construction, maintenance/repair, restoration and insect control in log homes. I can also answer questions pertaining to wood properties, characteristics and performance as they relate to log home applications. Additionally, I can answer questions pertaining to residential construction and repair, some engineering and trade issues.

Experience in the area

I have been in the log home and construction industry for 38 years, 10 years in a specialty contracting field and 28 years in the log home field. My company has designed, produced and supplied over 3,000 log homes and built over 500 and restored over 600 during that 28 year period. I was a volunter in AllExperts for several years and somehow fell off the map. I answered hundreds of questions during that term and had a very high rating.


I authored a monthly column in an in house publication expressing the Vice President and General Manager's "Observations and Insights" which was distributed to approximately 300 employees and management.


I have a BS Accounting degree from the University of Illinois, 1963, and a Master of Business Administration degree from the University of Chicago, 1968. I have participated in numerous relevant seminars over the years including an intense two week broad business administration seminar at the University of Pennsylvania Wharton School of Business, 1978. I have participated in the National Association of Home Builders Graduate Builders continuing education program.
