Discover Our Alumni - Dan San Buenaventura, Class of 2012

“One hundred percent positive attitude each day” is how Dan San Buenaventura journeyed through high school, college, and still continues today. Dan “San” (as he was fondly referred to) is a 2012 graduate of GCP who, while at Guerin, was known for his perpetual smile, positive attitude, and willingness to help out in any way he could. After four years, he was practically the unanimous choice for the Spirit of Guerin Prep award. Dan is also a wonderful example of the variety of ways that our students have the opportunity to grow during their time at GCP.

He started out taking classes across the curriculum, from our Sullivan and Providence programs. He worked diligently throughout his high school career, always striving to outdo himself. His hard work paid off. Upon graduation, Dan attended Concordia University in River Forest where he majored in Computer Information Systems and graduated cum laude with a Bachelor’s degree. Dan is especially proud of his work and involvement with IEEE (Institute of Electrical and Electronic Engineers), an organization for students at all levels. He helped host many events for the organization along with his professors at Concordia and served as president for three years. Dan also worked in the undergraduate admissions office at Concordia and then moved on working as a temp in the Ulta Beauty corporate office.

Today, Dan works at ISSA (International Sanitary Supply Association) where he started as the database manager and was recently promoted to the IT manager. Dan, who loves working with technology and people, has enjoyed meeting customers who work with ISSA and showcasing the company’s cleaning products. He recently traveled to a tradeshow where he was able to meet both keynote speakers, Howie Mandel and Troy Aikman.

“ISSA is an amazing company,” said Dan. “It has been a blessing to see my hard work pay off and get to this point,” he added.

Dan plans to go back to school for a Master’s in Information Technology Management in the fall of 2018. He says if all goes according to plan he will graduate in May of 2020.
“I always plan for big things and just work my way towards them,” he said. “You need to have that 100% positive attitude each day; challenges may taunt us but we can’t let them bring us down.”

Dan is also a wonderful spiritual role model. He is part of the Knights of Columbus at his parish, St. Monica’s in Chicago, where he participates in many events. He was inducted as a 4th Degree Knight in the order in May of 2017.

When asked about his experiences at Guerin Prep and why parents should send their son or daughter to GP, Dan said, “Confidence and leadership – those are the two main things I got from Guerin.” He concluded, “Guerin Prep will be your second home; you will grow, make new friends, form new relationships, and be ready for your next journey when you cross the stage at graduation – you won’t regret making the decision to go there.”
