Client Testimonials

“After being with my previous accountants for 20 years, I felt that they had become complacent and not able to deliver on the type of services that my dental practice needed. As a result, I made a change to Tim Lott about 6 years ago, I have been totally impressed ever since. Tim and (the Dental CPA) team are extremely responsive, efficient, and have excellent follow-through. They help me to minimize my tax burden and to think about areas where I can grow my practice and improve its performance. Tim is very knowledgeable of the details of owning and operating a dental practice… And is shows in how well cared for I feel each and every year that I file my corporate and personal taxes. If you are looking for excellence, Tim Lott is the best!”

“I have transitioned through several CPA’s, always feeling like we were stumbling through the dark together. My time spent with Joshua Waller and the Dental CPAs has provided the light I needed to truly see my vision clearly, and the plan to make this vision a reality. My only regret is not making the transition sooner.”

“I’ve depended upon Tim Lott and the Naden/Lean Dental CPAs team to manage and grow my practice for over fifteen years. He’s been instrumental in helping me evaluate opportunities and strategize to reach the potential of my dental practice. Tim’s experience with associate relationships has been invaluable. It’s nice to have a business advisor who is competent and skilled in his profession – beyond the nuts and bolts of accounting and tax.”

“I believe I was one of Tim Lott’s first clients when he joined the Naden/Lean and the Dental CPAs team. It is hard to believe, but that was almost 20 years ago. As general dentists, he was instrumental in helping me (and my then business partner) work through some difficult issues. In his kind, objective manner we were able to create a most amazing practice. After I specialized in endodontics, I was ready to start my new practice. I turned to Tim and Lance Jacob for my accounting needs. Once again they have been extremely helpful in my negotiations with associates. It was real neat when my associate’s attorney knew of Tim and described him as fair, knowledgeable and honest.”

“My partner and I decided to open our dental practice from scratch a few months ago. We knew we needed an accountant who had good experience in the dental field to guide us through the process. We were glad that we chose to work with Ron Ehman at Naden/Lean’s Dental CPAs. Without a doubt, Mr. Ehman and Naden/Lean are very experienced with the accounting aspect of dentistry. He also provided us numerous examples of excellent advice in all aspects of the startup process. Mr. Ehman really helped to smoothly guide us through the whole project. We feel very comfortable working with Mr. Ehman. He is very reliable and always gets things done as promised. He is responsible and is always there for us when we need him. He is efficient and is always on top of things. Most importantly, we feel that he truly cares about us and wants our future office to do well. It feels like we are working as a team to achieve our goals. Overall, our experience with Mr. Ehman and Naden/Lean’s Dental CPAs has been excellent. We are very satisfied with their services and would highly recommend them to any dental office that needs accounting services.”

“I have been a client of Naden/Lean and the Dental CPAs since 1977. Through the years I have appreciated your unwavering support as financial advisors and accountants. Whenever I have needed your service and support you have always been available. As I developed a dental practice through the years, your words of advice have served as a significant guidance for me. Each individual with whom I have dealt with through the years has been willing to go the extra mile to either meet with me or provide telephone support, even during hours when the office was closed. In addition, from a more empirical view, I have always sensed that your staff genuinely cares that your clients succeed not only professionally, but also personally. The achievement of balance in life for your clients by providing sound financial advice is truly your forte.”
