Joseph Gregar Junior Seminar Mission Statement:

Jump to Topics | Overview | Instructors

The mission of the Joseph Gregar Junior Member Seminar of the ASGS is to foster the junior members by focusing on basic techniques and procedures used in Scientific Glassblowing. The goal of the annual seminar is to increase exposure to necessary skills as well as provide expert instruction from the industries top glassblowers.

A brief history of how the Joseph Gregar Junior Member Seminar came to be.

The first “Junior Member Workshop” was held in 1987 at the Boston, Massachusetts Symposium. The program stated ” Instruction and demonstration of techniques as requested by Junior Members attending”. The next year in 1988 at the Atlantic City, New Jersey Symposium was the first Seminar that Joseph Gregar was an instructor. Since then Mr. Gregar has been instrumental in making the Seminar what it is today. 2013 was the last year Mr. Gregar was in charge of the Seminar. Mike Souza took over as the interim leader in 2014 until a more permanent person could be found. This only lasted one year. In 2015 Christopher Bock officially stepped up to guide the Seminar into the future.
