AUTHOR BIO:
Lynn M. Griesemer became a long-distance swimmer in 2020 and has swum around more than 69 different islands in Tampa Bay, Florida and beyond. Her current swim goal is to complete an open water 10K swim (6.2 miles) in all 50 states. She has completed 15 different states, with 10 more planned for 2026.
Lynn is a veteran, mother of six, grandmother, and author of 12 books on various topics, including marriage, homebirth, and public speaking.
She was the first person to swim around St. Pete Beach, Florida in 2022. At the age of 62, Lynn and her swim partner Ken Morgan were the Oldest Male-Female Tandem Team to complete 20 Bridges around Manhattan (28.5 miles in 10 hours, 11 minutes).
Lynn Griesemer began her swimming journey at the age of five when her father introduced her to the joy of swimming. Although she wasn’t a competitive swimmer, she developed a passion for swimming over the years. She became a long-distance swimmer in 2020 and has swum around more than 69 different islands in Tampa Bay, Florida and beyond.
She was the first person to swim around St. Pete Beach, FL in 2022. At the age of 62, Lynn and her swim partner Ken Morgan were the Oldest Male-Female Tandem Team to complete the 20 Bridges swim around Manhattan, which is 28.5 miles. Four days after the completion of her New York City swim on 8/9/25, Lynn decided to write a book because she felt transformed by the experience. In fact, most of the books she’s written over the years have come from a place of conviction. Her current swimming goal is to complete an open water 10K swim, (6.2 miles) in all 50 states. She has completed 15 different states, with 10 more planned for 2026.
In addition to swimming, Lynn’s other passions include advocating for long-term happy marriage and husband and wife homebirth. Lynn is a mother of six grown children and grandmother of five. Although she was career-oriented in her twenties, she believes her greatest joy is that she had a large family. She’s been a family mom for three decades and homeschooled her six children from 1994-2016. She enjoyed learning from her children and watching them blossom over the years.
Before children, Lynn was an Army Officer and later, a Human Resources Manager. She received her B.A. in Psychology from Boston University and M.S. in Human Resources Management and Development from Chapman University.
After four hospital births between 1988 and 1993, Lynn and her husband Bob decided to give birth at home alone for the birth of their two youngest in 1996 and 2002. Not much was written on unassisted homebirth, and she was inspired to publish “Unassisted Homebirth: An Act of Love” in 1998. She is considered a pioneer in the field of unassisted birth (or freebirth), which is giving birth without a doctor or midwife.
Another strong interest: public speaking. As a former shy child, Lynn believes effective speaking is necessary for everyone, especially those in leadership and influential positions. She’s written several books on public speaking, with emphasis on children ages 10-18. A bucket list item of hers is to find an expert marketing and business partner to help promote and implement her public speaking programs.
Lynn has two more book ideas swimming around in her head – one about island swimming and another about the fifty state10Ks. Her mentor is advising her to write a book on unassisted homebirth, and she’s trying to make time to follow through. Lynn has written 13 books on various topics and is determined to write a handful more in her lifetime.
SUMMARY OF BOOK:
How and Why a 62-year old woman swam 28.5 miles around Manhattan Island in New York City.
On a clear August morning in 2025, with perfect weather and water conditions, two swimmers began what would be the swim of their lifetime. At the age of 62 both Lynn Griesemer and Ken Morgan were the Oldest Male-Female Tandem Swim Team to complete 20 Bridges, one of the three prestigious swims that constitute the Triple Crown of Open Water Swimming.
The swim was transformational for Lynn and she says it changed her life. Four days later, she decided to start writing a book about it. Swimming Around Manhattan: Find Your Passion ~Make it Happen is a story of a long-distance swimmer who circumnavigated the 28.5-mile island in New York City, but this swimmer had a few obstacles to overcome before the big day.
Lynn encourages readers to find and follow their passion. She says, “Your passion can make the seemingly impossible become possible. When your desire is strong, tenacity follows. Worthwhile pursuits require endurance and focus, discipline and commitment. It’s that simple.
Lynn is a champion of the underdog and shows what life looks like when you have a burning desire to follow your passion. It’s never too late to do something great!
