Born August 22, 1985 in New Bedford, MA, he graduated from All Saints Elementary School in 1999, and Bishop Stang High School in 2003.

Gannon graduated with honors from Westfield State University in 2007 with a Bachelor of Science in Criminal Justice, a Master’s with honors from Massachusetts Maritime Academy with a degree in Emergency Management in 2011, and the MBTA Municipal Police Academy. Gannon’s internships included Nantucket Police, Westfield Police, and earned certifications as an EMT and Life Saving Instructor.

Gannon started his career at Stonehill College in 2007 as a member of the Campus Police before joining the Yarmouth Police Department in 2010. Gannon was part of the Emergency Management Unit, a part-time member of the Proactive Anti-Crime Team, and he was the first K-9 narcotics officer for YPD.

After retiring the K-9 narcotics officer, Gannon acquired the patrol dog who was also injured at the scene of the crime.

Sean leaves a legacy of high moral integrity, infectious humor, and collaborative work with colleagues. He enjoyed travel, working with his hands, donating his time to Big Brother/Big Sister and being outside. He loved spending time with his family and friends. Sean was deeply intuitive and inspired others to be there best selves.

Sean leaves his wife, Dara (Bryan), his parents, Patrick and Denise, his siblings, Timothy and his fiance Mary, Martha and her husband Derrick, his in-laws Kathy and Dean Bryan, and their son Ross, along with many relatives and friends.

Whatever Sean did, he gave 100% of himself. He will be profoundly missed by his family, colleagues, and friends.
