John Ohman
Director of Hedging Analytics

John began his career in the securities and futures industry in 1983 employed as a registered representative and futures associated person with a major broker/dealer. Upon acquiring his first PC in 1985, he began his quest of developing risk management and hedging analytics utilizing statistics and Black Sholes option pricing models. Between 1985 and 1996, his primary focus was on the mortgage banking industry. He incorporated the analytics and processes to assist mortgage bankers to cope with interest rate volatility and risk. In 1996, John formed Flatirons Capital Management LLC (FCM) consulting solely with mortgage bankers. Over the next 20 years, FCM assisted over 100 mortgage bankers in maximizing revenues in excess of $1 billion annual origination of mortgage loans. In 2016, over 20 years since its inception, John sold his stake in FCM to its employees. Relocating to west central Minnesota, he took it upon himself to bring the same analytics to grain producers. With this 30 years of bona fide hedging knowledge, he seeks to instill growers to incorporate overall farm enterprise revenue management practices with traditional grain advisor recommendations on annual marketing plans.
Sam Ohman
CEO – Risk Management Advisor

Sam graduated from North Dakota State University in the spring of 2020 with a degree in finance. He joined Heartland in the summer of 2020 as the office manager and registered commodity futures broker. Working under John and Heartland Founder, Brad Weinrich, quickly proved to be a far better learning experience than anything learned in the classroom. In June of 2021, Brad decided it was time to ‘hang up his spurs’ and handed the reins of the company to Sam, who now serves as its Principal and CEO. He is excited with this new opportunity to work with current Heartland clients as well as grow the business in West Central Minnesota and beyond.
In his free time, Sam enjoys golf and fishing in the summer and hunting in the fall and winter months. He also enjoys traveling and spending time with his wife Tori, and their children Emerson and Michael.
John Tweed
Risk Management Advisor

John Tweed is a Commodity Broker and Risk Management Advisor with Heartland Commodities & Securities. He works with farmers and ranchers across the Midwest to help manage price risk and develop practical marketing strategies for grain and livestock.
Raised on a family farm in North Dakota, Tweed spent much of his early life involved in cow-calf and grain operation. Growing up around agriculture gave him firsthand exposure to the financial pressures and uncertainty producers face each year.
He began studying and paper trading commodity markets as a freshman in high school, using simulated speculative trades to better understand how markets function and why prices move the way they do.
Today his work centers on helping producers look past market noise and concentrate on the needs of their own operation. By evaluating breakevens, revenue targets, and risk tolerance, he helps producers use tools such as futures and options as part of a disciplined risk management approach.
