She successfully enhanced workflows, worked directly with top-tier clients, and collaborated with senior leaders to improve efficiencies and increase margins.

Gina met Erik in 1995 and they married in 1998. Just ten months into their marriage, Gina was diagnosed with stage 3 Non-Hodgkin’s Lymphoma. After a successful stem-cell transplant, she would overcome three additional bouts with cancer. Defying the odds of what she was told by doctors, in 2006, she welcomed a baby girl into this world. In 2016, Gina suffered cardiac arrest at the age of 44, and after being in an induced coma, walked out of the hospital just ten days later.

Gina has enjoyed growing in her role as Co-founder of Think GREAT since 2008, and she truly appreciates the opportunity to help others to experience a greater life – personally and professionally.
