Going on 35 years of selling exclusively GMC trucks and suv’s, love dealing with people, I guess that’s why I have fun doing what I do. I have 5 children and 4 grandkids with another granddaughter due to arrive this October! Enjoy fishing, golf but love coaching baseball, coached my 38 yr. old and am now coaching my 11 yr. old!! Been married to my Lords blessing for 34 years, and have served as Deacon for past 13 years at our church. Believe in fairness and honesty, I tell all my friends and customers that I am in the repeat business!
