Our Mission
Landmark Advisors was founded with the sole purpose of enhancing the financial position of Ranchers all across the US. For nearly a decade our founders, Lee and Spencer, have a proven track record of helping clients make big decisions incorporating data, analysis, and experience in the commodity markets. Their sister company, MP Agrilytics has grown the respect of livestock market participants including: ranchers, feeders, packers, further processors, brokers, & speculators world wide.
They spent years building Landmark Advisors on the foundation of their finance backgrounds, layered with exclusive market tracking analysis and personal experience, as ranchers themselves, to build a proprietary process that has proven to be robustly competitive against every other policy strategy.
Our heart at Landmark is to humbly help ranchers see the most return for their hard work.
Our team
Spencer T. Prosser
Owner, Agent
Spencer founded Landmark Advisors along side his long time business partner and friend, Lee McGlamery. After pursuing PRF for his own operation, he soon discovered the many missed advantages in the program and the fallacies in other insurance companies out there. He spent two years developing a proprietary software system to capitalize on those gaps and create tremendous advantage. The product he created was so successful, he began Landmark Advisors in order to assist other ranchers, like himself to achieve the same success with the program.
​
Landmark Advisors is a sister company to MP Agrilytics (co-owned by Spencer) in order to serve further needs of the ranching community.
Spencer's years at MP Agrilytics has provided tremendous experience as it was built to provide critical research to over 20% of the cattle-on-feed industry in the US as well as a wide scope of processors, traders, hedge funds, and industry affiliates in the US and abroad with the purpose of providing objective and valuable livestock information.

Spencer attended Colorado State University in Ag Business, Finance, and graduate courses in Ag Economics. During graduate school he worked for the livestock futures broker, Compass Ag Solutions in Ft Collins Colorado. Later, he was in the risk management department for Adams Land and Cattle Co (a top 10 cattle feeder) in Broken Bow, NE before going out on his own with Lee McGlamery to start MP Agrilytics.
As an Arizona native, Spencer was raised on a large diversified ranch in northern Arizona called the -T- and he resides on the -T- ranch with his 5 kids and wife Meghan.
