Craig was my wife’s professor/teacher at the CSUN MBA program at the time I was starting a new company and looking to retain a CPA firm. Because the business was in a specialized arena, we were looking for a firm with that particular industry experience. Kathy introduced us and we retained Dalton, Mathias & Deever after just one meeting. That was back in 1993. We have been with the firm ever since for all our personal tax preparation and our business needs. In addition to tax advice we have relied upon DM&D's sound business management direction and never regretted it. No matter how large or how small your business is, Craig and his team at Dalton, Mathias & Deever have the experience and know-how to do the job, efficiently and effectively.
