Relationships Are Important

At Dugan & Lopatka, we realize the value of a strong relationship with our clients. We firmly believe that the more our clients trust us, the more they interact with us, the greater the benefits they gain from our expertise and the higher their satisfaction. We also recognize that in any new relationship, we must take the initiative to prove we deserve your trust.

Communication is one of the keys to building client trust. Our primary job is to ensure communications between you and us and to maintain quality service. To that end, we offer unlimited phone support. We encourage you to call us frequently. We strive to maintain an open, highly responsive relationship with our clients, not just during periods of compliance work, but throughout the year.

We assign a team of professionals to serve you including at least two firm principals. Our goal is to 1) have someone always available when you call and 2) to pull in the team of people with the specific skills, knowledge and experience you need today and in the future.

If you want a better, stronger relationship with your CPA or if you are tired of poor communications offered by your accountants, please contact Dugan & Lopatka, CPAs at (630) 665-4440.
