I've got this bush and I'd like to get a few more but I'm not sure what it's called. It has white flowers in early June. I'm in Colorado and it gets full sun.
At this point, my guess is some kind of Spirea. This extremely variable genus has some plants with a very similar growth habit, inflorescence, bloom time, leaf shape, and leaf placement of your shrub. If the shrub looked similar to the one pictured below when in bloom, you have a spirea.

I just saw a couple at the nursery. Looks like you're right -- Specifically, Snowmound Spirea. – Ultravi01 Aug 2 '14 at 21:29
