At St. Petersburg College (SPC), one professor stands out not just for her expertise, but for the way she transforms the lives of her students. Dr. Lynn Grinnell—a retired Air Force veteran, sustainability advocate, and a guiding force in the College of Business—is the embodiment of passion, grace, and dedication.
Dr. Grinnell doesn’t just teach—she empowers. She has a unique ability to make her students feel that no matter where they are in life, they can rise above challenges and create an impact.
Her belief in her students is unwavering, and her encouragement fuels their confidence to achieve their dreams and go beyond what they thought possible.

Leading the Charge in Sustainability and Net Impact
As the leader of SPC’s Bachelor’s in Sustainability program and the faculty advisor for Net Impact, Dr. Grinnell’s mission is clear: to inspire students to take actionable steps toward a better future.
Through her work with Net Impact, she encourages students to go above and beyond in sharing the message of what we can do to protect our environment, both locally here in Florida and on a global scale.
Whether tackling issues of environmental stewardship, corporate responsibility, or sustainable innovation, Dr. Grinnell is a champion of creating leaders who are prepared to make meaningful contributions to the world.
Her passion for sustainability is deeply rooted in helping students achieve certifications that make them stand out in their careers. Certifications like the prestigious LEED (Leadership in Energy and Environmental Design) and the Green Innovations Certificate are transformative for students.
Dr. Grinnell is right there alongside them, offering guidance and support. Her dedication ensures that students are not just prepared to enter the workforce but are inspired to lead with purpose and innovation.

A Legacy of Service and Dedication
Her life is a testament to resilience and service. Dr. Grinnell’s military career not only shaped her disciplined work ethic but also brought her a love story—she met her husband while serving in the U.S. Air Force.
Today, she channels that same discipline and heart into shaping the next generation of leaders. Watching her work is awe-inspiring; her energy and dedication seem limitless. She pours herself into every task, ensuring that her students not only learn but also grow as individuals.

Inspiring Women to Break Barriers
For women students, Dr. Grinnell is especially inspiring. Her journey from serving her country to leading a cutting-edge academic program shows that no dream is too big.
As one of the first women in an Operations career field, she controlled fighter planes and became the first woman Master of Air Defense—a prestigious skill rating achieved by only 100 pilots and controllers over 25 years. Her trailblazing career reminds women that they can overcome any barrier, break into male-dominated fields, and leave a lasting legacy.
