Marc Montgomery
Marc MontgomeryChairman of the Board
Marc Montgomery is an executive in the aerospace industry. He brings 37 years of management experience to the GRO Team having held a variety of leadership positions in both project and line management. A life-long proponent of continuous improvement, Marc holds a NASA-certified Master Black Belt in Lean Six Sigma process improvement techniques. Marc experienced the challenges of raising a profoundly gifted child in the 1980s when little information and even fewer resources were available to guide him and his wife in how to nurture and support their son. Many of the puzzling and challenging behaviors they witnessed they now understand to be manifestations of the “overexcitabilities” found among those in the gifted spectrum. Only when they accidentally stumbled upon an early college entrance program did their son begin to thrive in the educational environment for the first time. Marc is committed to ensuring parents and professionals have the information they need to support and understand the gifted population.

“The founders of GRO are a multitalented and dedicated group of individuals whose aim is to further our understanding of gifted children and their needs across domains of development – physical, emotional, social, and psychological. GRO intends to pursue a thoughtful and comprehensive research program and to make their findings available to all, thereby raising awareness of this unique group within society at large.”
Dr. Susan Daniels, Co-Founder and Educational Director, Summit Center, Professor and Educational Consultant, and Co-Author of Living with Intensity
“Imagine having research data that provides objective and accurate evidence of many issues we in the gifted community already see anecdotally. Picture parents and educators being able to discuss the social, emotional, and health concerns surrounding giftedness using scientific information to back up their opinions. Then consider a group of uniquely talented individuals making those outcomes their passion. That’s GRO. And I’m excited about the possibilities their work will afford all of us!”
