Exceeding Expectations Since 1967

Get to Know Shamrock Builders

Shamrock Builders was founded in 1967 by Roger O’Herren. In the early 80s, He brought his son, Greg O’Herren, and his nephew, George Geiger, into the business after they graduated from DePauw University. When Roger retired, Greg and George took over as co-owners and have run and grown the company ever since.

Our company has one of the longest and strongest histories of any builder in the Indianapolis, IN, market. We began as a custom home builder, and over the years we have built over 700 residential homes. In 1996, we expanded our services to include commercial construction. Since that time, we have built over 1,000,000 + square feet of ground-up commercial buildings, including self-storage facilities, office buildings, and dental and medical offices.

Our experience, longevity, and expertise are unmatched in the Midwest. We are proud of the fact that the majority of our staff members and contractors have worked with us for over 20 years, ensuring our customers receive consistent, expert services.
