Built by Justin Chase Ford
Licensed financial professional and Marine Corps veteran. Built Yipshanks for the golfers in his life because the rounds matter, and the tools should respect that without harvesting your data.
Great with portfolios. Catastrophic with a 7-iron. The name basically narrates my round. Whether you're brand new to the game or playing scratch, you're in good company here.
