I currently hold coaching certifications from USA Triathlon and USA Swimming. My background is in competitive swimming, and coached age I group swimmers for six years before transitioning into triathlon in 2008. I recently finished first in my age group at Ironman Mont-Tremblant, completed my 11th Ironman and and in the process qualified for my 5th Ironman World Championships.

Working full time in biotech research, I has a M.S. and B.S. in chemistry and bring my analytical background into my coaching. I am currently working with everyone from beginners to ITU World Championship qualifiers
