CLIENT SUCCESS STORIES

REAL RESULTS FOR REAL BUSINESSES

Don't just take our word for it—hear from the leaders who trust SEK to guide their financial future.

Working with the SEK Outsourced CFO & Accounting team has been an absolute game changer for my business. I never have to question the accuracy of our financials or wonder if something has been missed. Their responsiveness and clarity give me so much confidence as a business owner. They do not just handle the numbers - they help me understand them, plan around them, and make smarter decisions because of them. I would recommend SEK’s Outsourced CFO & Accounting Services to any growth focused business owner who wants accuracy, strategy, and a team they can truly rely on.

Morgan Griffin
Owner & Registered Nurse, Face Forward Skin Care Center

My wife and I were in the middle of a business acquisition. At the time our current accountant was really dropping the ball. With the quick commitment and dedication from Aaron Althouse, Patti Wildasin, and the SEK crew, our biggest problems were soon resolved and the books up to date. As new business owners there was a multitude of new things to learn and understand. They provided efficient training and support to get us operating smoothly and with minimal issues. To put it simply, we are so pleased with our service. 10 out of 10 would recommend the professional services from SEK. 

Zachary Mortimer
Owner, York Sheet Metal, Inc.

We've had the privilege of working with SEK for more than 20 years, and their consistent professionalism, accuracy, and strategic guidance have been invaluable. They understand our business, anticipate our needs, and always go the extra mile to ensure our financial health and compliance.  A trusted partner in every sense.

A Retirement Services Plan Client

SEK is an excellent company to do you audit. They are timely, efficient and professional. I have a very complicated audit, and they listen and understand how we run. I'd refer them to anyone.

Amy Brown
Executive Director, Pennsylvania Association of Conservation Districts

SEK provides unparalleled service with integrity, experience and knowledge.  They understand the needs of the client and work diligently to meet those needs and expectations with a professional and positive demeanor.

Caroline Royer
Chief Financial Support Services Officer, Greencastle-Antrim School District

I am able to speak with someone who understands my QuickBooks questions and helps me deal with any problems I am having. The same holds true for any tax questions, as well, federal and state.

A Hagerstown Tax & ACTS Client

SEK provides great audits for our small Second Class Township and their team of employees are professional, qualified and knowledgeable in the field of government accounting. I have found them trustworthy and respectful during and after the audit. They respond promptly to inquiries throughout the year when a question may arise or counsel is needed relating to the Township's finances always recommending what might help and improve the Township. Working with SEK through many years has been a pleasure. They have helped me as the Secretary/Treasurer greatly to learn better ways to improve and manage the finances of the Township.
