The Gem Academy Team

Jim Hershey

Founder / Executive Director

For the last 14 years Jim has specialized exclusively in therapeutic work with overweight teens and young adults, with an emphasis on immersion programs, long term treatment and aftercare. He has amassed over 5000 hours of direct client work in this specialty putting Jim in a small, exclusive group of clinicians in the world. As a member of the Obesity Action Coalition Jim is a constant advocate and educator regarding the causes of obesity and effective interventions.

His work in this field began in 2007. This was after 4 years as a clinician working with college athletes in the field of sport psychology.  Jim moved from Phoenix Arizona to Fresno California to take a position at the world’s first boarding school for overweight teens. During his tenure he held the roles of therapist, clinical consultant, and program director and clinical director.

Among his peers he was known for his tireless determination and commitment to the kids and their families. Mark Twain once said, “the two most important days in a person’s life are the day they were born,  and the day they find out why.”

Shorty after Jim began his career at the boarding school his “why” was realized. “There was a level of bravery, sacrifice and hope that I would see every day in the kids.  It made you want to be the absolute best you could be for them. With everything they were bringing to the fight, they deserved every bit of that”

Jim’s dedication to the students and their families allowed him to build long standing relationships. Through Jim’s investment and continued involvement with his students and families, Jim recognized the need for a far more comprehensive support structure for recently transitioned students. This became the catalyst for Gem Academy as a long term solution for adolescent obesity.

Gem was born over a decade+ long process of evaluation of prior experience, refined practice, the latest health research and new research into areas of achievement, performance, habit formation and character. But the most critical influence into building Gem has been the shared personal experiences of hundreds of students over the last 14 years. Sharing their successes and challenges has created a better understanding of what is critically needed to support these students for the long run.

Through his professional and educational pursuits Jim has had diverse and eclectic experiences as a tradesman, working musician, on-air radio personality, and collegiate athlete and captain.

Jim is a Wisconsin native but has been a resident of the Phoenix area for 16 of the last 20 years. He and his wife have a seven year old little boy and a four year old little girl.

Carly Lane

Community Mentor


Carly attended and studied dance and psychology at Western Wyoming Community College and has been an avid lover of the dance form since she was 3 years old. Growing up in the dance world she had the opportunity to learn many different styles that she has loved teaching and sharing with others for the past 8 years. Her love of, and belief in movement without judgment allows her to teach in a unique way that encourages reconnection with, and love for the body and one’s self every step of the journey. She specializes in ballet, contemporary, lyrical, modern, jazz, hip hop and dance improvisation techniques.

Prior to Gem, Carly spent much of her time working with youth to learn coping skills, breathing techniques and expression through the arts. As a children’s art teacher she used many different materials and mediums to help others learn how to take everyday objects and things that might otherwise have been thrown away, and turn it into something completely new that they could be proud of. Carly uses these skills of hard work, grit and creativity to remind others that you can take any situation and, with the right steps and motivation, transform it into something that serves you.

In her own life Carly has dedicated much of her time to studying DBT, CBT  and positive affirmations as they have helped her to overcome negative self image in her own life. When she saw that her mission aligned seamlessly with Gem she knew she wanted to be apart of the team. Carly brings her fun, bubbly and gentle personality as she works each day to help others see their value and worth allowing them to put themselves first and find internal motivation to create the lives they absolutely and authentically love.

When not at GEM Carly enjoys creating her own art, hiking, traveling, playing the ukulele, caring for her plants and spending time with her wonderful husband and puppy.
