Our Reputation


We could not ask for a more professional team to manage our CPA and Tax needs. Our year end Audited Statement is completed in a timely manner - and without our having to get into the arcane details of accounting practices; Adam does a super job of presenting tax options which integrate our corporate options with our personal returns (we are a Sub-S). We appreciate eight years of professional support!


Wilson and Stephenie O.


The ladies and gentlemen that run Schutte & Hilgendorf are always helpful and on time with anything you throw at them. I have dealt with several CPA firms over the years since my husband and I have owned a couple of business's and we have found that Schutte & Hilgendorf have been the absolute best! Many thanks to each and everyone of them!


Barbara W. 


My partner and I interviewed a few businesses to do our business and personal taxes. S & H won hands down. They are knowledgeable and personable, and deal with our quirky ways with grace! Love that we can email and get answers back quickly. We are so glad we chose S&H!


Cathy Kamper. PLLC 


I really appreciate Schutte & Hilgendorf, PLLC- CPA's because they are courteous, friendly and always do a job well done! They submit everything needed in a timely matter and, they truly "look out" for those of us who just can't digest the 'accounting thing.' Their staff always makes you feel like you're the only one they working with. A sincere and grateful thank you!


Diversified Concrete Crafters, Inc P


After many years with another CPA, we were very frustrated with the level of service we were receiving. Being self-employed, has it's unique obstacles that can be overwhelming at tax time. Slater and Rutherford (Adam & Gidget) sat with my husband and I for nearly 2 hours, answering our questions, and taking the time to explain our best course of action. We really appreciate the time they took with us, and I just feel better not having to panic over taxes!


Terri Marotto Atkins


I really enjoyed work with Schutte & Hilgendorf, PLLC for our annual financial review and 990 tax preparations. Great communication, quick turn around time once we got started and an overall great experience. Looking forward to working with them next year.

Nina Seim


Schutte & Hilgendorg have provided professional services and advice for us since we incorporated our non-profit over 10 years ago. They are excellent to work with and always respond to our needs and questions in a timely manner with professional answers. I particularly recommend them for any non-profit tax and accounting work and they have served those I recommended with excellent service.


Arizona Cowboy Poets Gathering J


Slater & Rutherford process my payroll, business taxes, and personal taxes, and they do so in a consistently professional manner.
