I am a husband and father of six with one Grandson. My wife and I have been married for 25 years now, and we look forward to another 25 years! I love to play golf, read Anne Rice novels, and to engage in good conversations. I believe that customer satisfaction is the core foundation of any business. If the customer is taken care of above and beyond what is expected, then everything else will fall into place.

I had an absolutely fantastic experience at Russ Darrow Mazda of Greenfield, and it’s all thanks to Jason and Nick. From start to finish, they were transparent, professional, and incredibly helpful. Jas Mazda of Greenfield, and it’s all thanks to Jason and Nick. From start to finish, they were transparent, professional, and incredibly helpful. Jason took the time to walk me through every detail of the vehicle I was interested in. There was no pressure, no gimmicks—just honest answers and a genuine willingness to help. Nick was equally outstanding, explaining the financing options clearly and ensuring I understood all the terms. Their customer service is truly top-tier. You can tell they care more about building relationships than just making sales. I left feeling confident, respected, and thrilled with my purchase. If you’re in the market for a new or used Mazda—or just want to work with people who value honesty and transparency—go see Jason and Nick at Russ Darrow Mazda of Greenfield. You won’t regret it! More
