Owner/InstructorBryan Cooke, Owner

Bryan holds a BS degree in Mechanical Engineering and an MS degree in Engineering Management, both from Drexel University. He has also taken various continuing education classes, including Vibration Analysis, Root Cause Analysis, and Reliability Methods. Bryan spent 20 years as a plant engineer and has also spent 10 years as a reliability consultant and corporate trainer. He realized a love for teaching when he was a corporate trainer and as a Scout leader. Bryan has wanted to get into the teaching field for several years. He looked into public schools and colleges, but there were many roadblocks. Then he heard about Mathnasium and checked it out. Bryan agrees with the integrity and ideals Mathnasium promotes and the teaching methodology is powerful and understandable. The teaching method is similar to how he learned Math from his mother and grandfather. "We 'mathed' as well as 'read' while I was growing up." Bryan sees Mathnasium as a way that he can pass on his love for math and give back to the community. Bryan has lived in the Cherry Hill area for almost 30 years with his wife and 3 children. He has been involved with Boy Scouts as an assistant Scout Master and enjoys camping, tennis, golf and swimming.
