This video will help you find our three main chemistry classrooms (namely AC 1303, AC 2501 and AC 2507) as well as my office (AC 2568) at Mt. Hood Community College in Gresham, Oregon, USA. (Summer 2026 Version) To get to all of these locations, go to the "F" or "G" parking lots (or as close to them as possible), both of which are located near the main MHCC entrance on NE 29th street and NE Kane Dr. in Gresham ). AC 1303 is on the lower level of the campus, adjacent to the Planetarium. AC 2501, AC 2507 and my office (AC 2568) are located on the upper level of campus, and all are very close to the "F" and "G" parking lots. Let me know if you have any questions! Peace!
