A Partnership Built on Trust: Greg Sandrock – The Cornerstone Agency and ProAg

For more than 20 years, Greg Sandrock and The Cornerstone Agency have partnered with ProAg to serve farmers and ranchers. Over the years, they’ve shared a commitment to education, service and doing what’s right for customers.

As mergers and acquisitions reshaped the marketplace, Greg’s relationship with ProAg began during a period of consolidation in the crop insurance industry.

Over the years, one thing has remained constant: a customer-first mindset. “We share the same values,” Greg said. “Educating our clients, prioritizing customer service and helping farm families get back on their feet when storms and claims occur.” That shared mindset has strengthened a partnership that continues to grow today.

For Greg, ProAg stands apart because of its commitment to communication and relationships. “ProAg takes the extra step in keeping us informed when farm clients have claims,” he said. “Their leadership has been consistent, and the approach to claims has been fair and consistent over the years.”

As the crop insurance industry continues to evolve, Greg appreciates ProAg’s thoughtful approach to innovation. “We must all strive to review, improve, and anticipate the future,” he said. “ProAg acknowledges the human relationship element first and then seeks ways to invest in systems and processes that advance agents and policyholders.”

Throughout the years, Greg says ProAg has consistently made agents feel like true partners. “From the CEO and management team to claims, marketing, and sales, we’ve always had a seat at the table,” he said. “Success comes when all parties sit down together and make plans to grow.”

When asked what has made the biggest difference over the years, Greg points to the people behind the organization. “There have been many folks along the way who have impacted our agency’s success,” he said. “I especially appreciate Kendall Jones and her team for caring the way they do and being available when needed. I also want to recognize the adjusting team that responds when weather hits and helps keep clients informed.”

One story stands out above all others. It isn’t a single claim or event, but a pattern that has repeated itself throughout his career. “When a farm operator calls at 5:00 in the morning because they’re worried, stressed and unsure what comes next, you realize the importance of having a dependable AIP behind you,” Greg said. “I’ve texted adjusters at 5:00 a.m. and called supervisors late at night, and they respond because they care.”

For Greg, that dependability can be summed up in one word: consistency. “Our farm clients need dependability and consistency,” he said.

As ProAg celebrates its 100th anniversary, partnerships like the one with Greg Sandrock and The Cornerstone Agency reflect the values that have guided the company for a century: trust, service, communication and a commitment to helping farmers, ranchers and agents succeed.

“We have had a great relationship with ProAg for more than 20 years,” Greg said. “I look forward to many great decades to come.”
