According to a 2007 study of 90,000 employees in 18 countries, the single highest driver of employee engagement is whether or not senior management is seen as genuinely interested in employees’ well-being.

BUSINESS boostcamp  helps individuals and organizations thrive! While most training offerings address either skill development or wellness, our program does both. Through a dynamic combination of coaching, teaching, energy rubrics, workstyle analysis and mindfulness practices, this engaging, interactive program is designed to strengthen workplace wellness, drive high performance and boost organizational success.

Founded by certified success coach Maria Katrien Heslin, BUSINESS boostcamp sessions feature experts specific to the solutions you need. Team members specialize in coaching, consulting, business, management, leadership, communications, marketing, public relations, operations, strategic planning, budgeting, career services, resume development, interview preparation, public speaking, teaching, training, nonprofit and government management, human resource management, wellness, yoga and meditation.

The idea for BUSINESS boostcamp came to Maria about three years ago while taking yoga classes on the pier of her favorite Jersey Shore town. Feeling how much joy, clarity, energy, vibrancy and focus yoga gave her, she soon realized that these sensations weren't just experienced on the mat, but were carrying into her daily life. These benefits had an especially huge impact on her approach to work, success and happiness, and she felt that others could and definitely deserved to feel the same way. She set out determined to see how she could help others feel such similar personal and professional bliss, and thus the BUSINESS boostcamp concept was born.


Maria's firm, Thrive Coaching & Development, provides Success & Career Coaching services to college students preparing to enter the work world and professionals seeking job search support or career transformation. Boostcamp is a program of Thrive.

She co-authored The Roadmap, An Overview of Business, used by 30,000 Indiana University Kelley School of Business students, and served as the City of Bloomington's first female Deputy Mayor until she opened her own firm in Fall 2013. Her passion is helping people and organizations achieve joy and success as they define it.

As Deputy Mayor Maria introduced and led the strategic planning process; reinvented the budgeting approach and managed development of the $75 million budget. She also launched the City's wellness initiative; led the team that identified more than $6 million in innovations and savings; set policy; and managed the 750-person organization.

The wit and wisdom of Renaissance man and raconteur Joe Lee is rare and delightful. Joe has been meditating in the Zen tradition for many years and has developed a keen interest in the many other forms of meditation and mindfulness. With professional experiences that range from being a business owner, real estate agent, emcee, professional speaker, teacher, artist, author, creative director and clown, Joe credits his ability to thrive in so many hats (sometimes literally) to the focus, peace and clarity he experiences from his meditation practices.

When not sitting on his cushion he spends a good deal of his time as a cartoonist, illustrator and writer. He is the author and illustrator of "Dante for Beginners,"  “Greek Mythology for Beginners” and "The History of Clowns for Beginners," a subject he knows well as a graduate of Ringling Brothers., Barnum and Bailey's Clown College and a veteran of Ringling, King Brothers-Cole, and Hoxie Brothers Circuses.

Joe also has illustrated a dozen other titles in the ongoing For Beginners series. He is the editorial cartoonist for the Bloomington Herald-Times and staff illustrator for Our Brown County and Into Art Magazines, and an active freelance illustrator for many other publishers. Recently, Joe added real estate broker to his resume and is proud to be associated with F.C. Tucker.
