For more than a century, Prism Bank has raised the standard for community banking. We combine deep local expertise, dedicated bankers, and an unwavering commitment to your success.
In 1909, Oklahoma State Bank was founded in Mulhall. For more than a century, we fueled the growth of businesses and communities across the state. In 2023, we reimagined our future with a new name that reflects clarity, perspective, and an ambitious vision for modern banking. Today, Prism Bank continues a legacy of strong relationships, innovative solutions, and uncompromising service. And we’re ready to help you achieve your next financial success.
We believe success means going above and beyond for the communities we serve. In 2025 alone, our team supported more than 18 donation and volunteer initiatives. We invested time, resources, and leadership to strengthen families, children and the organizations that support them. Together, we’re empowering businesses, helping our neighbors, and building a stronger future for everyone.
We listen, share ideas, and pitch in because we know we’re stronger together. We check our egos at the door because we are a team executing as one.
Curiosity drives us. Whether it’s new skills, fresh ideas, or innovative ways to serve our clients, we strive for improvement each day. For us, learning isn’t just a goal. It’s a mindset that fuels success.
We care about our work, our clients, and our impact. We bring our whole selves and give it our all, because the work we do matters for our clients.
When we make a promise, we follow through. We show up, step up, and stick with it until it’s done. Our word means something, and we take pride in keeping it.
We hold ourselves to a higher standard. We own our work, our challenges, and our wins because we’re always moving forward together.
We take the time to truly know you, your goals, and your bigger picture. That connection helps us create momentum at every stage of life.
We stay ahead of your needs with insight and support to keep you moving forward. We never stop looking for opportunities to strengthen your financial future.
When you reach out, we won’t keep you waiting. We help you stay on track with attentive service that keeps you focused on your goals.
