Another remote conversion on the books for Corelation with $2.3 billion TTCU Federal Credit Union

SAN DIEGO, CA (November 19, 2020) — Credit union core processor Corelation Inc. continues their streak of successful remote core conversions with TTCU Federal Credit Union ($2.3 billion assets; 140,000 members; Tulsa, OK) completing their upgrade to KeyStone in October 2020. TTCU’s conversion marked the tenth fully remote conversion for Corelation.

Close collaboration between TTCU, Corelation, and the credit union’s third-party vendors set the stage for a successful implementation.

“It’s normal to feel nervous going into a conversion, but the meticulous preparations from both organizations instilled confidence in our team. Everything went off without a hitch; this is the third core conversion I have experienced, and it was by far the smoothest,” remarked TTCU Federal Credit Union President & CEO Tim Lyons.

“A key reason we selected KeyStone was because Corelation’s culture and core values complimented ours – we believe in inspiring a passion for excellence, embracing change, and promoting teamwork and a fun atmosphere,” noted Lyons. “Corelation has done a fantastic job of meshing our cultures, and most importantly – we feel like we have already achieved an excellent relationship with Corelation.”

Offering words of advice for credit unions converting in the future, Lyons stressed the importance of taking full advantage of the opportunity to examine internal processes and find new efficiencies during the pre-conversion process.

As TTCU plans for the future, their operational strategy places a strong emphasis on business intelligence and data mining.

“With KeyStone, our ability to exceed our members’ expectations has increased exponentially, and we are well positioned for the future in the digital age that we’re in,” added Lyons. “We are especially excited to put KeyInsight [KeyStone’s Relationship Manager] to work – the technology offers our analysts much more effective tools.”

“Throughout the conversion process, TTCU Federal Credit Union demonstrated a high level of dedication and collaboration,” expressed Theresa Benavidez, Corelation President & CEO. “Partnering with a like-minded credit union such as TTCU allowed for a smooth implementation, even when we are operating remotely. A great accomplishment for both of our organizations.”
