He has followed this passion his entire life, he earned a science degree from Texas A & M University and practiced his science for over thirty years within the Federal Government as a Meteorologist, before starting his own consultation company. He has become an internationally known and respected meteorologist, often called upon for his expertise in severe weather and other atmospheric conditions and phenomena.
