The church sits at the corner of Dahlia and Hampden. Traffic is busy at this intersections with no protected left-hand turn (if traveling west on Hampden from I25).
Options: pass the intersection and try turning into the west parking lot.
One that works well is to turn in as if you are going to Starbucks, go through the parking lot to Happy canyon, make a right and then immediate left. Take that to Dahlia and make a right, the south parking lot to Bethany is right there! Good Luck!
