    Like another former client posted...I had been with John Diehl & asso since 2004. All went BAD when David Griffiths took over after John retired...Still haven't done my 2022 taxes as Griffiths waited til last minute to do taxes & suggested tax fraud! Seriously..Gave every excuse. For taking so long..Wife had cancer. He had Covid...such a bad man! Didn't even send my tax packet back! Hard getting that info...All the old employees GONE..

    Total clown show. I was with Diehl and Company for 20 years. John Diehl was excellent. Highly competent. Highly professional. David Griffiths is the complete opposite. He is not competent and not professional. He has a bizarre laid back mentality that exhibits a complete lack of wanting to meet customer expectations. But he will take your money. He actuallydoes not really take his job very seriously. If this is the kind of clown you want doing your taxes well, have at it. CPAs are everywhere. It will be easy to find one better. Just look one up and pick one. 100% chance you will do better.

    Diehl & Co is a great accountancy firm, especially for small and start-up companies. They are very responsive to requests and willing to impart their knowledge and associated recommendations. I have been very impressed with the service they have provided.
