David has been doing mine and my family’s taxes for years and I can honestly say working with him has taken so much stress off me. I can confidently run my business knowing he’s equipped me with the knowledge of how to be organized and prepared come tax season and any questions I have along the way he is always so thorough and makes himself accessible to guide us. Our appointment when it’s time to file is always a pleasure since he’s so kind and the best in the business, no one knows their stuff the way David does.

How can I say enough about David Keil and his team? My father chose John Keil years ago to be his trusted tax man, and now John’s son David is amazing as well! Year after year they have delivered strategies for short and long term planning that have been so profitable. They have treated us like family, going out of their way to help my father as he aged. It has been David’s habit to review all paperwork and the entire tax return personally with us before he submits anything, answering all questions with kindness, in easy to understand terms!! David is full of good ideas to help save time, money and to strategize tax issues. It never ceases to amaze me how efficient… read full review

We were referred to David by friends in 2023. Before working with him, we used a non-local service that operated entirely through email, which often led to communication challenges.

Since partnering with David, we’ve been extremely pleased with the level of attention and service he provides. He takes the time to clearly explain tax laws and how they apply to our specific situation. Each year, we spend a couple of hours reviewing everything together to ensure accuracy.

His secure online portal makes it easy to upload documents and stay organized. We truly appreciate his thoroughness and professionalism, and we plan to continue working with David for many years to come!
