Denver

From US 36, Heading Northwest: Take the Table Mesa/Foothills Parkway exit, stay in the left of the two exit lanes to reach the Foothills Parkway (CO Hwy 157). Proceed though the stoplights at Baseline and Colorado Avenues, and turn left at Arapahoe. Take another left at the next light onto Marine Street (the street sign on the right will indicate 38th Street). Follow Marine until just before the stop sign where it dead-ends at 30th Street. Make a U-turn and stop by the meters in front of 3100 Marine Street, the tallest building on the south side of the street. One of the research assistants who will be working with the twins will be watching for you at the front of the building. Please remain in your car so you can be greeted and shown where to park and enter the building.
