Director, Mathematics
Responsible for coordinating and supporting Achieve’s work to develop and lead an organizational vision, agenda, and lines of work around mathematics. I provide mathematics content expertise across all of Achieve’s initiatives and support to states on mathematics standards implementation and assessment support, including the development of tools and products for use by states and districts.

Leadership Team, Co-director of Professional Development. This was a 5 year, $8.7 million National Science Foundation grant targeting middle school mathematics teachers.

Assistant Dean, College of Education
Academic Liaison for Partnerships, Strategic Educational Alliances

Chair – Mathematics Department (2010-2013)
Chair – Maricopa Mathematics Instructional Council (2009-2013)
Senior Leadership for $1.1 million National Science Foundation partnership grant with Arizona State University: Mentoring Students through Critical Transition Points (MCTP). (2013)
Lead Member for Maricopa Colleges on the Arizona Articulation Task Force, Math (2009-present)
Residential Faculty – Mathematics (2002-2013)
Summer / Evening Chair, Scottsdale Community College (2004-2007)
As a professor of mathematics I taught courses from introductory algebra through calculus and mathematics for elementary teachers. As chair of the instructional council I managed the committee responsible for all math curriculum decisions in the Maricopa district and served as communicator to the district administration and the state universities. My campus chair duties included hiring, scheduling, evaluation of instruction, resolution of student issues, and working with administration. My involvement also included designing and implementing mathematics professional development for elementary and middle school and working with state policy makers to improve PARCC engagement. As the instructional council chair I worked to lead a redesign project for the district’s developmental mathematics program. This project involved over 40 faculty members from around the district.

In this capacity I worked with Pat Thompson on the National Science Foundation Teacher Professional Continuum research grant. Also with ASU, I worked with Marilyn Carlson’s National Science Foundation MSP research grant. My duties with these grants included working with secondary teachers, providing professional development workshops, training Professional Learning Community (PLC) facilitators, and working to refine graduate-level coursework for secondary teachers. Additionally, I worked on the redevelopment of the Reformed Teaching Observation Protocol (RTOP) training in the summer of 2007 and I was designated as an official trainer for those who will be using the RTOP in practice. (Note: These projects began with the Center for Research on Education in Science, Mathematics, Engineering and Technology before moving to RIMSE.)

In this capacity I worked as both a research assistant and a professional learning community facilitator in the Teacher Professional Continuum project.

As chair, I had oversight of the entire mathematics program for the college across all modalities, including a significant distance learning program. This involved hiring, evaluation, and supervision of approximately 70 mathematics faculty, oversight of curriculum development, and serving as high school dual enrollment faculty coordinator. I also served as representative for the Maricopa mathematics instructional council, competency coordinator for the North Central Association (Higher Learning Commission) accreditation process, and implementation coordinator of a grant from the Pew Center for Academic Transformation.

I taught courses in prealgebra, algebra, geometry, honors geometry, math analysis, math analysis with review, calculus, honors calculus and honors math seminar (cryptography and discrete mathematics in partnership with ASU). My extracurricular activities included Academic Decathlon coach (4+ years), sponsor for numerous competitions, mountain bike club sponsor, and computer club sponsor. My other activities involved leading technology related in-services along with the design and implementation of the school’s original web site. For the 1998-1999 school year I was selected as an initial participant in Arizona State University’s Cooperative University School Program (CUSP) master teacher exchange program to spend one year as a full-time faculty member in the mathematics department at the university. In this capacity, I taught calculus, participated in student teacher supervision, and interacted with faculty to strengthen the ties between high schools and the university.

In this capacity I gained experience across different instructional modalities: classroom, distance learning (print and internet based) and concurrent (dual) enrollment. I was also involved in curriculum development for college algebra distance learning (both print and internet based). I also served as the lead instructor for internet based College Algebra.

Acted as sole mathematics faculty (adjunct). I taught courses in intermediate algebra and mathematical concepts (mathematics for elementary majors).
