Building a better financial tomorrow through service, education, and advocacy

Limestone Federal Credit Union (Limestone FCU) is a leading financial institution dedicated to empowering its members to achieve greater financial independence.

We are excited to announce our expansion into the community of Sault Ste. Marie, located on the campus of Lake Superior State University (LSSU). With a strong history of serving our members and a commitment to personalized service, combined with cutting-edge technology, Limestone FCU aims to revolutionize banking and make a positive impact on the local economy.


What sets us apart? When you step into one of our branches, you’ll encounter a team that exudes passion for their work and genuinely enjoys building relationships with our members. As a member of Limestone FCU, you will become a part-owner of our cooperative, giving you a voice in our operations and decision-making process.

Apart from exceptional member service, we have invested significantly in technology to provide personalized banking experience. Our state-of-the-art mobile app empowers you to open an account and fully fund it digitally, as well as set up transactions within your account and with other financial institutions. Our Mobile App allows you to conveniently manage your debit and credit cards without the need for multiple applications. You can download our mobile app here.


One standout feature of our mobile app is the ability to make instant remote deposits of checks. No more waiting in line or wondering when funds will be available. The majority of our mobile check deposits are processed within five minutes, offering you a swift and hassle-free experience.


Convenience is paramount to us! If a debit transaction is flagged for potential fraud, you’ll receive an instant text notification. You can conveniently respond with a simple “yes” or “no” to verify the transaction’s validity. The entire process takes place in real-time, resulting in immediate approval at the register if the transaction is legitimate.


Additionally, our members can set up their LFCU debit cards on Venmo, the renowned platform for person-to-person transfers. Though bank accounts cannot be connected just yet, members can still enjoy all the benefits combined with the security features and money transfers through the LFCU debit card.


At the core of our success is our team of dedicated professionals, led by CEO Jennifer C. Watson. With over 30 years of experience in the financial industry, Watson holds deep roots in the Sault Ste. Marie area. “Our team is driven by a shared passion for serving the membership, extending our commitment to the entire Upper Peninsula of Michigan.” Says, Watson.


While Limestone FCU may not have originated in Sault Ste. Marie, we are committed to serving the area and the entire Upper Peninsula. We have made a significant investment in student education through our on-campus branch at Lake Superior State University, known as The Hub @ LSSU. This branch caters to the needs of students, offering a mix of in-person and digital services to serve the entire community of Chippewa County and beyond. Heading our initiative in Sault Ste. Marie is our Branch Manager, Chelsey Zeeryp, who brings a wealth of experience to the role. Her deep understanding of the membership and dedication to providing exceptional member service make her an invaluable asset to our team.


At Limestone FCU, we are committed to providing progressive initiatives that prioritize member convenience and satisfaction. While we may not have every individual feature under the sun, we strive to integrate with existing services and leverage technology to offer you the best possible banking experience. Our commitment to keeping you informed, protected, and empowered is at the heart of our approach.
