Daniel Tillwick, age 61 of St Petersburg Florida, passed away unexpectedly while vacationing in Cancun, Mexico on June 23, 2023. His loss was completely unexpected and his family is shocked and deeply saddened by the tremendous loss. They love and miss him more than words can express.

Dan was an accomplished Engineer - he was a licensed Professional Engineer in both Florida and California and was a licensed Residential Contractor in Florida. He started his own construction business in 2015, Willow Homes LLC, where he and his wife enjoyed building a residential rentals business together, serving their St Petersburg FL community. In the earlier part of his career, he was a Supply Chain and Business Development executive at several Engineering companies, including as COO for Solicore (2008-2015), Senior Director of Mechanical Solutions at Jabil (2002-2008), and VP/GM at Tracewell Systems (1999-2002).

Dan earned an MBA from Drake University, and held a Bachelors of Science in Chemical Engineering from Virginia Tech. After college, he proudly served his country in the United States Navy, serving in the Active Duty Nuclear Submarine Service and the Navy Reserves, until he retired as a Commander in 2001.

Family meant more to Dan than anything in the world, and his children were by far his proudest accomplishments. His wife Kelly was his real life princess and best friend whom he loved terribly and cherished with all his heart. Dan cherished his friends deeply - he will be remembered as a smart, loyal, gregarious, passionate, funny, and caring person by all who were fortunate enough to know him.

Dan was also a passionate fitness enthusiast - his proudest achievement was training for and successfully completing a full IRONMAN in 2006. He was an avid pickleball player and loved the camaraderie and friendships he made on and off the court. He also loved being a full-time member of the St Pete Half Century Softball Club where he treasured his teammates and the memories they made together on the baseball diamond. He had a strict conditioning routine where, rain or shine, you could find him rollerblading every morning through the Placido Bayou neighborhood with his two beloved dogs, Willow & Elora.

Dan is survived by his loving wife Kelly Witherspoon, his adult children Trevor (Justina) Tillwick and Jacquelyn Tillwick, his beloved brother Jeffrey (Betty Jane) Tillwick and sister Karen (Joe) Pierce, and the mother of his children Renee (Rick) Flowers.

A celebration of life will be held on Saturday, July 8th at 11am at BridgePoint Church Downtown campus in St Petersburg, FL. Dress attire is casual. Address is 737 3rd Ave N, St. Petersburg, FL 33701.

In lieu of flowers please consider a donation to Willow Cares, a 501c3 non-profit he founded with his wife to assist veterans needing to modify their homes to match their needs. Dan was passionate about helping people in need and enjoyed giving back to his community with his skills, and his wife will continue honoring his legacy through Willow Cares.
