My involvement in the lighting industry started in 1995. In this time I have been immersed myself in different facets of the industry including indoor and outdoor lighting, safety and security, lighting and human health, and lighting standards. Since 1999 I have been involved with several standard writing committees within the Illuminating Engineering Society of North America producing over six standard documents. Teaching has been a part of my career since I began in the industry in 1995, teaching to diverse groups from high school students to seasoned lighting professionals. Having a diverse background has allowed me to produce lighting designs, verify compliance, calculations, and photometric and equipment verification in the office. However I have also had field experience with commissioning, field survey and verification, and troubleshooting of field designs and equipment issues. I am available nationwide for your witness needs.
