True Power isn’t just a brand. It’s a way of being.

After a lifetime of moving beyond multiple chronic health diagnoses, I learned that we can be unlimited - when we move ourselves out of our own way.

Among innumerable client engagements, Jennifer has facilitated many strategic discussions regarding sensitive, confidential subject matter for national expert panels, conferences, and top level executive discussions, specializing in guiding emotionally-charged conflict to collaborative agreement. She works with live audiences and has been featured as an expert panelist, keynote speaker, and radio show host. Jennifer has also been featured on Fox Atlanta, CBS and many other media outlets.

“I’ve worked with JMac at companies of various sizes spanning for profit and not for profit over the past 15 years. JMac always delivered as promised and consistently achieved more than I had hoped regarding the team, culture, and alignment.”

- Jackie Breiter, Chief Operations Officer

“Jennifer is one of the most inspirational people I’ve ever met! She is insightful, creative and exceptionally skilled in helping individuals break through to reach their full potential!”

- RoseAnn Colesante, HR Professional

When JMac was a non-profit executive, she was also a serious workaholic. And it cost her.

By 1998 she was diagnosed with a chronic health condition. After having been told she would take pharmaceuticals for the remainder of her life, Jennifer chose a different path. Within two years, she had transformed her health - and her life.

Since 2002, over 90% of Jennifer’s clients have originated from word-of-mouth referrals that began when others witnessed the way she led her team, and the way she reignited her wellbeing. From multiple requests for her counsel, The Prosperity Formula was born, which became the primary tool within The JMac Method.

Throughout the years, Jennifer has had to practice what she preaches to move through divorce, breast cancer, and the bankruptcy that followed them. She’s been on the receiving end of multiple crimes, and lives to tell reflective, humorous stories. Her 4’10” stature creates a disarming tone as she shares relatable anecdotes and the wisdom to help move through all of life’s adventures with greater ease and joy.
