Maggie Rickman
Maggie is a Muay Thai instructor, yoga teacher, fitness professional and retired fighter. She has always been passionate about fitness and learning new things. If you asked her at a young age what she thought she would do as her career, Maggie would have said, “either a speech writer for the President or a triathlete.”
While neither of those things actually happened (Maggie can’t swim and she never worked in politics), she did eventually turn her love of fitness and learning into her career.

Maggie began her martial arts journey because she was searching for a workout that would challenge her body and her mind. She was seeking an activity where she was actually learning something, rather than simply mindlessly working out. Maggie discovered Muay Thai and immediately fell in love.

With her dedication to her training over the years and her love for sport, Maggie decided that she wanted to make a change in her life’s work. She wanted to contribute something positive to the world. She knew that for her, when she was working in the corporate world, the hour or two she spent training each day was the best part of her day. Maggie hoped she could bring that same joy to other people.

So she quit her job as a busy litigation attorney at a fast paced Manhattan law firm, sold all of her belongings, and moved to Thailand to dedicate herself to training and fighting. Maggie spent 2 years living in a Muay Thai camp in Thailand training twice a day, six days a week. She trained alongside high level fighters such as Kanongsuk Chuwatthana, Jomthong Chuwattana, Kongfah Aood Donmuang, and Yothin FA Group and fought for such promotions as MBK Fight Night, M-150, Songkran Celebration, and the Queen’s Birthday Celebration.

In addition to spending much of her life training Martial Arts, Maggie has also been dedicated to her yoga practice. She found her way into a yoga room shortly after beginning her martial arts training and has been practicing yoga for over 15 years. Maggie completed her 200 hour yoga teacher training while living in Thailand. She has been teaching yoga for over 6 years, specializing in Hatha, Vinyasa and Restorative styles.

Maggie was able to turn her love of learning, fitness and fun into her profession. She has been teaching Muay Thai, yoga, and functional fitness since returning from Thailand!

Over her many years of training, Maggie has become passionate about educating her students about muscle activation, mobility and recovery as a way to keep their joints and muscles healthy. These practices will allow them to optimize their training, while also reducing their risk of injury. She and Danny hold seminars teaching these systems and the importance of including them into everyone’s daily training routines.

Maggie is forever a student and attends seminars and workshops to increase her knowledge base as both an athlete and a teacher.

Danny Millet
Danny Millet
Danny Millet is a Fitness Professional, a retired professional fighter and an active member of the local Muay Thai community who judges fights and trains with upcoming amateur and professional competitors.
After completing a day of work, Danny would rush to his martial arts gym to maximize his training time. Practicing and competing in many disciplines, including Boxing, Judo, Brazillian Ju-Jitsu, and MMA, he fell in love with Muay Thai. We believe it’s because the shorts have sparkly letters.

For many years Danny was an electrician who knew there was more to life than just punching a clock and splicing wires for 10 hours out of the day. He donated his belongings to the local veteran’s hall and put his 2-week notice in to pursue a fighting career in Thailand.

For 2 years Danny trained at well-respected gyms alongside high-level fighters like KongFah Aood DonMuang, Kanongsuk ChuWatthana, JomThong ChuWatthana, YoThin FA Group and fought in prestigious stadium shows such as Rajadamnern, Lumphini, Petch Buncha, M150, and MBK Fight Night.

On the long flight back to the USA, Danny knew this was his calling. He devoted his time to sharing his love and knowledge of Muay Thai and the many weight loss and fitness benefits of training in martial arts.

“I want to keep training deep into my 70s and beyond.”

It’s not just about competing or fight training, Danny is a student first, who seeks out other educational systems towards health and fitness. He’s a Certified Kettlebell Instructor (HKC) and is currently enrolled in Precision Nutrition, Functional Movement Screening, and attends a plethora of Speed & Strength seminars.

“Muay Thai Boxing helped me lose weight, get in shape, gain confidence, and build my self-esteem. My goal is to get people to do the same. Have fun, get fit and feel good.”
