To get to the laboratory

Coming from Denver...

Take US36 ("Denver-Boulder Turnpike") towards Boulder. Take the first Boulder exit (Foothills Parkway). The off-ramp immediately splits left and right. Take the left side. (If you miss it, simply get back on Foothills Parkway going north.) Follow Foothills Parkway north, to Arapahoe Avenue (the third set of lights). Turn right onto Arapahoe, and go east. Follow the directions below.

Coming from the north...

Take US119 into Boulder. Stay on it when it becomes Foothills Parkway. Arapahoe Avenue will be the second set of lights in town. Turn left, and follow the directions below.

On Arapahoe Avenue...

Go 0.7 miles east of Foothills. Turn left onto Conestoga Street (third set of lights). Conestoga dead ends into Western Avenue. Turn right onto Western, and immediately turn left into our parking lot.

Our office door faces onto Western Avenue. The parking lot is immediately to the east of the building. Our sign is visible from the intersection of Conestoga and Western. Feel free to park in the spots with our signs, they're for your use.
