  • My financial advisor, Ameriprise, recommended Ralph Vix at Bayerkohler & Graff several years ago, and I've been so happy I made the switch from my previous accountant. While the cost is substantially more, it's worth it and you get what you pay for in life! Ralph has been instrumental in helping make my two small businesses more cost-effective. He's always available for even the most minor of questions. Since then, I've recommended several of my veterinary colleagues to utilize his services, and all have been happy with the switch!
