Company Information

For almost 40 continual years, American Windmills, located 40 miles east of Sacramento in Placerville and Diamond Springs California, has been serving the Windmill community.   American Windmills has grown from Paul Petrocchi working part time to a full time successful partnership with Ellen Sattler (that’s me!)  We also employ local machinists and skilled laborers.  We know Windmills and water pumping systems better than almost anyone else. 

Paul Petrocchi is a licensed contractor (#620131) in California.   Paul, along with Ellen Sattler, are certified Windmillers having earned their accreditation at the New Mexico State University at Las Cruces.  We are members of the International Molinological Society.
