"Dream big, plan well, work hard, smile always, and good things will happen." Is the philosophy here at Diamond Peak. We welcome you to our home on the Web.

Raftopoulos Ranches now known as Diamond Peak Cattle Company was established back in 1924 and got its humble start with a milk cow left behind by one of the ranch hands. To date over 2800 mother cows graze below the Diamond Peak and the surrounding areas of Northwest Colorado.

On average we market 500+ Registered and Diamond Commercial Bulls that will work in a high altitude environment. We invite you to learn more about our operation and our extensive AI program. Please browse through the Web site and let us know how we can serve you.
