We would like to thank the following Math Circle Leaders for their work to develop and guide the National Association of Math Circles. Their unending support of NAMC has brought the organization to where it is today.

**Hugo Rossi, **University of Utah *(Fall 2014)*

Dr. Hugo Rossi has been involved with mathematical outreach for most of his career, most recently as director of the Mathematics and Science Education Center at the University of Utah. He received his Ph.D. in 1960 from MIT. After a postdoctoral position at the University of California, Berkeley, he spent four years at Princeton University. He worked for 11 years at Brandeis University before moving to the University of Utah in 1974, where he has remained since.

Dr. Rossi has served as the chair of the Mathematics Department and as Dean of the College of Science. In addition, he is an American Mathematical Society Fellow, and he has been the Vice President of the American Mathematical Society, Deputy Director of the Mathematical Sciences Research Institute (MSRI), and Chairman of the Board of Directors of MSRI. His research interests have been in several complex variables, complex geometry and Lie group representations.

**Peter Trapa,** University of Utah *(Fall 2013-Summer 2014)*

Dr. Peter Trapa founded the Utah Math Circle in 2001 and has served as Director continuously since, with the exception of three year-long interruptions. He founded the Utah Math Teachers’ Circle in 2007. During the 2013-2014 academic year, he served as the Director of NAMC.

Dr. Trapa earned his Ph.D. in mathematics from MIT and held postdoctoral positions at Harvard and the Institute for Advanced Study in Princeton before joining the faculty at the University of Utah where he is now Professor and Chair. His research interests are in the representation theory of reductive groups.

**Dave Auckly,** Kansas State University *(2010-2012)*

Dr. Dave Auckly earned his Ph.D. at the University of Michigan and then held a postdoctoral position at UT Austin followed by an NSF postdoc at UC Berkeley. He then moved to Kansas State University before taking the Associate Director position at MSRI. His research interests cover a broad range of geometry/topology and overlap with PDE, mathematical physics and algebraic geometry.

Dr. Auckly has been involved in many special educational programs, including helping to incorporate mathematics into a residential college at the University of Michigan, and creating a unique “Brainstorming and Barnstorming” program at KSU.

**Brandy Wiegers,** Central Washington University *(2007-2009, Fall 2012-Summer 2013)*

Dr. Brandy Wiegers served as the founding Director of the National Association of Math Circles, serving in that capacity from 2007 to 2009 and again as Director during academic year 2012-2013. From 2014-2016, she served as the Associate Director.

Dr. Wiegers is currently the Director of the Kittitas Valley Math Circle. She has also served as the Director of the San Francisco Math Circle, Oakland/East Bay Math Circle, Bay Area Circle for Teachers, and UC Davis Explore Math programs. Dr. Wiegers received her Ph.D. in Applied Mathematics from the University of California, Davis in 2008. After her Ph.D., she worked on various STEM outreach projects as a Project Director of Mathematical Outreach and Enrichment for the Mathematical Sciences Research Institute in Berkeley and San Francisco State University.
