Nicole (Nikki) Muller, 39, of Dallas, TX passed away Monday October 17, 2011. Nikki was a loving, giving and vibrant wife, mother, and friend to many. Her huge heart and passion for others was best reflected in her volunteer efforts; the dearest to her being the time she volunteered at the school her sons attend. One of her greatest joys was watching her sons play sports. She will forever be remembered by those whose lives she touched. Nikki is survived by her husband, John Muller, sons Zachary and Samuel, father Paul Masta, step-mother Maggie Masta, mother Amelia Weiderhold, stepfather Jim Weiderhold, and sister Jennifer West. In lieu of flowers the family requests donations to the Zach and Sam Muller Fund, Veritex Community Bank, 2101 Abrams Rd, Dallas, TX 75214.
