I tried to put a different twist on your initials. I used the white space that separates the sky from the mountain to form a "W" and used the middle peak to form an abstract "M". The mountain peak is a geographical reference to the Pac NW. It also shows strength and longevity in a way reminiscent of the Prudential/Gibraltar logo..
This mark is unique and stands apart in a world cluttered with "initial" logos.
