SineTech:  The story behind the name...

The name "SineTech" is an homage to our owner's great grandfather, William Sine.  William and his son-in-law, Bob Hoar, operated Sine's Service providing automotive and small engine repair for over 80 years in Manistique, MI!  At SineTech, owners Mike & Tanya Hoar, pledge to honor and continue the great legacy of business integrity and exceptional service established by William and Bob so many years ago.
