An accomplished life coach and consultant, Dr. Jordan Tourtelot Perzik holds a PhD in clinical psychology, a master of arts in clinical psychology from Antioch University, and a bachelor of science in film and television from Boston University. Strongly committed to environmental conservation, Dr. Jordan Perzik maintains membership in the International Dark-Sky Association (IDA).

The IDA engages in education and advocacy to prevent light pollution and preserve the beauty of the night sky. In collaboration with the Illuminating Engineering Society, the charitable organization published the Five Principles for Responsible Outdoor Lighting, which guide individuals and businesses in choosing safe and functional outdoor lighting that minimizes light pollution and wildlife disruption.

First, outdoor lighting should have a clear purpose. Before installing lighting, consider how it will affect wildlife. Whenever possible, opt for reflective paint rather than permanent lighting. Next, utilize targeted light that only illuminates a necessary area. Keep light levels low, noting that many surfaces reflect light into the night sky. Install timers and controls to allow lights to be shut off when they are not needed. Finally, use warm colors rather than shorter, blue-violet wavelength lights.
