Tiffany Larson

Tiffany is a Napa native. She graduated from Napa High School and Napa Valley College. She has developed a passion for fitness and wellness and helping others reach their goals by conquering obstacles.

She and Jeff married in 2001 and after having children she found herself at 217 pounds and not sure how it happened or how to get back. Determined to find herself again and achieve better health she started attending boot camp 5 days per week and never looked back.

Her belief: Fitness and wellness is journey, you never actually arrive, it doesn’t happen today or in 4 weeks or a year. It happens everyday of your life.

Tiffany helps clients in the program by offering support, answering questions and managing the boot camp program. She understands the stress of being a wife, a mommy, an employee and a business owner and can relate to the many obstacles we all face when it comes to making self care and fitness a priority in your life. She works behind the scenes making sure each boot camper has all the information and motivation they need to succeed at discovering and reaching their goals.

 


Joanna Mittman

Joanna has personally experienced the success that awaits the boot camper who puts her or his mind to achieving fitness and weight loss goals. She started attending boot camp in 2006 in the hopes of getting out of her gym membership rut. Fairly fit, but also overweight, she trained hard, lost fat, and grew strong and fit, but she still wanted to lose more weight. Although Jeff often asked about nutrition and told her to journal her food, she didn’t see the need because she was not a junk food eater, or even a sweets eater. She ate what she believed to be a pretty healthy diet (except maybe for those couple of glasses of wine after work every evening).

Finally, after buying her first pair of size 16 pants, Joanna attended a Boot Camp nutrition seminar on January 9, 2009. Jeff’s nutrition information clicked and the next day she began following the Rapid Fat Loss program and journaling her food (turns out she was a carb junkie). 35 pounds and 6 pants sizes later, she has become a Boot Camp trainer to share her enthusiasm for hard workouts with excellent technique, improved fitness and conscious nutrition choices. Boot Camp changed Joanna’s life, and she knows it can change yours too!

Aside from training at Boot Camp, Joanna is an attorney and a teacher at Napa Valley College. She has two wonderful grown children, who have always supported their boot camp addicted mother.

Tay Espinosa

Tay Espinosa was born in Chicago but raised mostly in Miami Florida. After graduating from the University of Miami with a bachelor’s degree in nursing Tay was commissioned as an officer in the Navy Nurse corps. She was stationed in the bay area where she met her husband Julio, a career naval officer.

In 1991 she was deployed to the Persian Gulf on the hospital ship, Mercy in support of Desert Storm. During the 9 month long deployment she began to run to work off stress. This habit continued upon return to the United States but seriously took hold about 10 years later when she ran her first marathon with Team in Training. The thrill and camaraderie of training for endurance events contributed to her interest in fitness and a healthy lifestyle. Going to a gym did not provide motivation or the “fun” factor she craved in her workouts until she found Adventure Boot Camp.

Tay has been an avid “boot camper” for 4 1/2 years. She has achieved and maintained a superior level of health and fitness through working with Jeff and Tiffany. Having the demands of two children, age 16 and 11, and a very busy husband she strives to take care of herself so she can take care of her family. As a coach, Tay wants to help others reach their health and fitness goals. She believes everyone has the capability to achieve a healthy lifestyle with the workout and nutrition support of Adventure Boot Camp.

  • N.E.S.T.A Certified Personal Trainer
  • Precision Nutrition Level 1 Coach

- Tay regularly teaches the Napa 12:15pm and is our Nutrition Coach

Carson Carattini

Carson is originally from San Jose, Ca, but has lived all over the Bay Area as well as spending some time in Charlotte, NC. He is a lifelong athlete, playing basketball and football, but mainly baseball  starting from the age of four all the way until the completion of High School.

While playing competitively may have ended, his passion for athletics never did, as he played intramurals in college and hoped to pursue sports at a professional level. In 2002 he began a coaching career, teaching middle school sports in the South Bay. Since then he has moved along to High School and AAU Club Basketball, where he currently coaches in Marin County. His passion for teaching athletes to be successful both on and off the court is what keeps him motivated and enthusiastic about coaching.

Shortly after becoming a resident of the Napa Valley in August of 2011, Carson connected with Fitness Revolution Napa and Napa Valley Adventure Boot Camp. Seeking a way to integrate fitness and basketball, NVABC was an obvious fit. It was only a matter of time until he found the added benefits of camp. His understanding of movement patterns, nutrition, and strength training have vastly improved with the help and guidance of Jeff and Tiffany. He hopes to share his passion of fitness and athletics with campers throughout the Valley, not to mention the vast array of knowledge and assistance NVABC has to offer.

Carson and his wife of two years Katherine, are really enjoying their new home in the Valley and their experience with NVABC. In the short time with camp each of them has lost 10 pounds, as well as a noticable change in body image. They know, this the first step in a lifetime of fitness, that anyone can achieve.

Having a host of health issues at a young age, including being obese, pre-diabetic, having high blood pressure, high cholesterol, and being sedentary for a number of years led her down a path of limitations and a lesser quality of life.  She slowly began making small but healthy changes in her life, which eventually led to big changes and over the course of approximately two years and she managed to shed a remarkable 90 pounds which she has kept off for over two years now.  She is now in excellent health and along the way she has discovered her passion for fitness, healthy eating, and helping others to achieve this as well.

She has since become a fitness enthusiast who enjoys all aspects of fitness and you can find her regularly cycling, jogging, boxing, doing bikram yoga, competing in mud runs such as the Tough Mudder, 5 & 10K races, sprint triathlons, and of course boot camp training.  She enjoys doing anything that challenges her physically and mentally.  Through her own personal experience she recognizes just how strong and amazing the human body is and what it is truly capable of.

Kat Martucci

Kat Martucci bio picKat Martucci was born and raised in Reno, NV. She moved to Napa to support her husband’s passion for wine. Kat began her involvement in sports when she was 15 and discovered her passion for running. To her running became very a source of therapy.

After years of running, cardio kick boxing and a variety of martial arts taught by her step-father she dealt with a chronic hip injury and was forbidden to do high impact sports by her doctor. This turning point in her life led her to riding long distance on her bike to replace high impact activity.

After moving to Napa she trained reformer Pilates for three years, but Kat had the desire and need for more intense athletic activity. She started Aerial Acrobats after her step father passed away as a tribute to him.

After joining Fitness Revolution / Napa Adventure Boot Camp she discovered how this was exactly what she needed to re-build her body and muscle and joint stability to move better, feel better and look better.

Kat now enjoys running, boot camp and aerial acrobats with much more strength and stability. Being a member of the program and interning as a coach has helped her understand fitness on a whole new level. She has reached goals that she didn’t think was possible.

Kat went to the Art Institute for Fashion Design and Revery Academy for Metal arts. She still enjoys designing and assembling clothing and jewelry but after owning her business for 7 years she discovered that she still had a deep desire to be a part of the fitness world.

Inspired to revisit her “youth” dream of being a fitness instructor she completed her A.C.E. Certification in August 2013.  She looks forward to motivating and inspiring others to reach their goals and inspiring others to be the best they can be!
