Your Sioux Falls CPA with a Personal Touch

Real expertise. Real relationships. Real results.

Meet the CPA Behind EDG CPA - Daniel Foster

When you look for an experienced CPA firm in Sioux Falls, you are likely looking for more than someone who just plugs numbers into software. You want someone who understands your business, answers your questions directly, and helps you make sense of complex financial situations. Running a business or managing family finances across Lincoln County means handling constant change. You deserve a certified public accountant in Sioux Falls, SD, who steps up as a true financial partner.

My name is Daniel Foster, CPA, and I built EDG CPA to offer exactly that. My path to accounting was not traditional, and that diverse background benefits your financial strategy today.

I started my academic journey earning a B.S. in Chemistry from the University of North Dakota. This scientific training taught me to analyze deep, technical data, a skill that translates directly to hunting for tax savings. From there, I moved into a corporate career within the oil and gas sector. Working in that complex, fast-moving field showed me how vital accurate financial planning is for operational survival. I knew I wanted to bring that level of institutional expertise directly to local business owners and families.

To pivot my career, I earned a Master of Professional Accountancy (MPA) from the University of South Dakota. I earned my CPA license in 2014, and I have spent over a decade working in both public accounting and private corporate finance.
When I am not analyzing financial statements, you might find me in the skies. As a Certified Flight Instructor, I know how to stay calm under pressure and teach complex concepts clearly. These technical skills require absolute precision, just like preparing a Form 1040 or an S-Corp tax return.
Most importantly, I am a family man proud to call this community home. My roots are right here, and I care deeply about helping businesses thrive throughout Sioux Falls and Harrisburg, SD.

Our Philosophy

An Experienced CPA Firm in Sioux Falls Built Around Your Needs

Many traditional accounting firms follow a rigid corporate structure. You might meet with a senior partner once, only to have your actual accounting work handed off to an entry-level staff member. When you have an urgent question about your cash flow or payroll compliance, you end up waiting days for a reply.
At EDG CPA, things are completely different. I operate as a boutique firm because I believe personalized, one-on-one service yields much better outcomes for your business. You get direct access to me for your tax planning, bookkeeping, and consulting needs.
This concierge-level approach is designed to give you peace of mind. You can potentially reduce your tax liabilities because your accountant actually understands your business model. You will never feel like just another file folder on a shelf.
