What our happy customers are saying about us!

""I wanted to drop a note to tell you all at Grindstone how happy I am with our engagement with Grindstone, Inc.. Dawn was great to work with (same for Jason toward the end), and Judi, my assigned caller, was the star of the show. She is just super. I learned a lot from her, and she even recommended a very nice book which I read and enjoyed. Dawn, Judi and I always had a nice time catching up on things during our weekly calls. I consider them friends. Grindstone provides outstanding service at a fair price. I will recommend you to others who need the services you offer. You have a great company!"" - David Long (Strategy Advocates)
