Directions to Our Longmont Office
Our Front Range office, right along Interstate 25 with a display building you can see from the highway. Walk-ins are welcome while we are open.

Friday, 9:00 AM to 4:00 PM
Closed weekends
This office serves Denver, Boulder, Longmont, Firestone, Frederick, Fort Collins, Loveland, Greeley and the Colorado Front Range. Please note the address is the EAST frontage road. There is a separate 9518 West I-25 Frontage Road directly across the interstate, and a map that sends you there leaves you on the wrong side of the highway.
How to get here
From I-25, coming north from Denver
- Take Exit 240, marked Highway 119, Longmont and Firestone. It is about 30 miles from Denver.
- The ramp splits. Keep right, following Firestone Boulevard East. Do not follow Highway 119 west toward Longmont.
- Take the first right onto the East I-25 Frontage Road.
- Drive south about a mile and a half. You will pass the large American Furniture Warehouse store.
- We are on your left, so watch for a gap in traffic to turn across.
If you reach the four way stop at Bella Rosa Parkway, you have gone about half a mile too far.
From I-25, coming south from Fort Collins or Loveland
- Take Exit 240, marked Highway 119, Longmont and Firestone.
- At the end of the ramp turn left, crossing over the interstate to the east side.
- Take the first right onto the East I-25 Frontage Road.
- Drive south about a mile and a half, past American Furniture Warehouse.
- We are on your left.
If you reach the four way stop at Bella Rosa Parkway, turn around. You are about half a mile past us.
From Boulder, without using the interstate
- Take the Diagonal Highway (119) northeast toward Longmont.
- Stay on Highway 119 through Longmont, where it becomes Ken Pratt Boulevard, then Firestone Boulevard as it crosses over Interstate 25.
- Just past the interstate, turn right onto the East I-25 Frontage Road.
- Drive south about a mile and a half. We are on your left.
When you arrive
- Look for our display building with wood-look metal siding. It looks like wood but it is steel, and it sits right along the frontage road.
- We are on the east side of Interstate 25, on the frontage road running alongside the northbound lanes.
- The property is a standalone lot with a single driveway straight off the frontage road.
