Ms. Ruckriegle is thankful for her Colorado roots and appreciates all the resources the West has to offer.  Before law school she worked for Costa Rica Outward Bound leading youth groups through outdoor adventures including rafting, coast-to-coast hikes, scuba diving, and surfing.  Her passion is especially strong for winter when she can enjoy her favorite activities: playing hockey and skiing in the backcountry.  She is fluent in Spanish and volunteers monthly for Project Safeguard assisting Spanish-speaking victims and survivors of domestic violence to increase their safety through the civil legal system in the Denver metro area.
