Prius/Hybrid specialist mechanic in Charlotte NC?

I've had my 2007 Prius since I bought it in 2013 with only 120,000 miles on it, have only 140,000 miles on it now and, being retired, would like to keep it in great condition for many years to come. As such, I would like to ask for recommendations for expert Prius service/mechanics from Prius owners in my area, which is Charlotte NC (which is right on the North Carolina / South Carolina border for folks not from around here).

Meanwhile, my sister has sent me a recommendation she received for Fournier Motor Company, which evidently specializes in hybrid cars. I'd love to hear from anybody who has gotten service from these folks, as to whether you can recommend them?

Thanks very much to anybody who has recommendations / referrals in the Charlotte area!
