RAYNHAM — It’s not often that the Raynham Public Library hosts a Renaissance Man to speak to kids and parents.
The career span of educator and now author Aaron L. Polansky, according to his resume, has included executive sales manager and designer for a multi-million-dollar landscape construction company; director of Massachusetts USA Wrestling; professional speaker; and school superintendent.
The latter job description applies to his role as superintendent of Old Colony Regional Vocational Technical High School in Rochester.
Prior to accepting that job, Polansky from 2008 to 2016 had been assistant principal and then principal at Bristol County Agricultural High School in Dighton.
His latest avocation is writing children’s books.
Polansky, a Natick native who lives in Raynham with his wife and six children, spoke to about 20 children and adults late Saturday morning inside the public library.
The 42-year-old Polansky read from his recently published first book “Dolphins in Trees,” subtitled “A children’s book with implications for all of us.”
The implicit theme he said he’s trying to convey in the guise of a fanciful tale is the importance of empathy and caring.
Polansky said as a professional educator he ascribes to the teaching theory known as “social and emotional learning,” or SEL for short, which seeks to establish a welcoming, collaborative and caring classroom climate.
During his visit to the library’s community room, he read from his 40-page book and engaged both children and adults in a brief question-and-answer session.
When one young boy asked why he had wanted to write a book, Polansky said in addition to being fun he wanted to help readers “think of ways to help other people.”
Polansky, who sat near a stack of books for signing and sale, said he was inspired to write his children’s book from having watched the 2017 movie “The Greatest Showman” — a musical film based loosely on the former Ringling Bros. and Barnum & Bailey Circus.
The idea to write it came to him while driving home with his wife, Rhonda.
“I think I just wrote a book in my head,” he remembers saying.
Polansky said from start to finish the writing process took him all of an hour and a half.
He said he called fellow educator Joy Kirr, author of “Shift This,” and asked her advice.
Kirr, he said, told him that California-based educational author turned publisher Dave Burgess, who wrote “Teach Like a Pirate,” and his wife Shelley, who co-authored “Lead Like a Pirate,” wanted to publish a children’s book.
Polansky pitched his idea to Shelley, who liked it, and eventually presented a proposed book contract from DBC Consulting (Dave Burgess Consulting) to his lawyer.
His lawyer, Polansky said, told him “That’s a good contract.”
Polansky said he’s already working on a second book, which will be for slightly older children.
The “Dolphins in Trees” title, he said, is meant to suggest that young students, no matter their background, are capable of achieving things beyond their imagination if they take risks and stretch their minds.
“I never imagined writing a children’s book. I was a dolphin in a tree,” he said.
Polansky said he was fortunate that the Burgesses were able to connect him with an illustrator named Genesis M. Kohler.
In addition to his role as a school superintendent, Polansky lists himself as CEO of Authentricity, a web site from which he offers his services as a professional, motivational speaker.
Polansky was a keynote speaker last November in Boston at the 18th annual Building Learning Communities 17 Education Conference.
He also will travel to Orlando in October to speak at a conference being held by the nonprofit Blue Ribbon Schools of Excellence at Disney World’s Yacht Club Resort.
Among those attending Polansky’s book event on Saturday were his wife, four of his six children, an aunt and uncle and his parents, David and Elaine.
“I’m bursting with pride — it’s amazing,” Elaine Polansky said.
“Dolphins in Trees” is available in both hardcover and paperback at Barnes & Noble and Amazon.
A description of the book on the Amazon website refers to Polansky’s book as “Dr. Seuss meets Tony Robbins.”
