She rises to new challenges as they are presented and always strives for excellence. I watched her mature over the four years we worked together, both personally and professionally.

I watched as she learned and became really good at working with suppliers to get the best deals, as well as finding suppliers to fit the needs and design criteria of the Engineers.
