Care Philosophy
I am a board-certified Genetic Counselor committed to supporting research to advance the understanding and treatment of neurogenetic disorders, with my primary research interests in Fragile X Syndrome and sex chromosome aneuploidy (SCA) conditions. Since 2008, I have served as the Genetic Counselor and Clinic and Research Coordinator for the Denver Fragile X Clinic and the eXtraordinarY Kids Clinic, both interdisciplinary clinics dedicated to advancing the standards of care through clinical trials and translational advancements. During my tenure, I have gained broad experience in medical research in developmental disabilities, successfully recruited and retained participants for more than a dozen clinical research studies, and facilitated dissemination of research results through collaborations with national advocacy groups, including the National Fragile X Foundation (NFXF), the Association of X&Y Variations (AXYS) and the Turner Syndrome Global Alliance, as well as professional organizations, including the National Society for Genetic Counselors (NSGC). My lifetime professional goals aim to improve the quality of life for individuals with neurogenetic disorders, including Fragile X Syndrome and SCAs. I am committed to patients, families, and professionals by providing translation of research findings in the field while supporting ongoing education and advocacy that promotes effective interventions and a better quality of life for these eXtraordinarY children.

Personal Interests
In my spare time, I enjoy snowboarding, gardening, and being with my family.

Volunteer Activities
Since 2013, I have volunteered as a Co-Chair for the Colorado Genetic Counselors Educational Symposium.

Public Speaking
