Owner/Coach 

David Mills

David joined the Rock Fitness team as a member in 2020 after a 5+ year journey back to fitness. The intensity of the workouts, variety of skills, and opportunity to move barbells again had him hooked. Fitness became a family affair once his wife and two teenage sons started attending classes in June 2021. His two daughters now can be found swinging on ropes and creating obstacle courses with gym equipment. The Rock Fitness family welcomed the Mills family into their tribe and is supportive of everyone seeking better health. David is excited to lead the community forward starting in March 2022.

 

David has worked in the nursing and health care industry for 20 years. He has seen the costly impact that disease and poor health has on individuals and families. He is motivated to help others achieve their health and life goals. His personal experience is that better fitness leads to more confidence, energy, and improved mental wellness. Gains in these areas all support his goal to strive daily to improve as a person, father, husband, and coach.

Coach 

Jamie Wuerthner

Jamie is a wife and mother of 3. Jamie grew up participating in competitive swimming but as life happens her fitness seemed to slip away from her. In January of 2014, Jamie began a strength & conditioning program and completely fell in love. Soon Jamie found that what started as an activity to lose weight turned into so much more. Her fitness journey became more about empowerment, strength, endurance, confidence and community than only physical appearance.

Jamie is passionate about meeting an athlete at their current ability. She believes true fitness is being the best version of yourself. Her experience has taught her that anyone can be an athlete

Coach 

Natalie Moncrief 

Natalie is married and raising 4 teenagers. She enjoys outdoor activities, listening to live music, and traveling. She has always led an active lifestyle. Growing up she watched her mom teach aerobics classes (sometimes inconspicuously working out in the back of the room) and her dad play baseball. Natalie enjoyed playing softball from little league through high school, and intramurally in college. Natalie has a competitive spirit and enjoys challenging herself and learning new things. She has participated in numerous races: 5k-half marathons, triathlons, Spartan and Tough Mudder obstacle course challenges, and functional fitness competitions. She strives to be a role model for healthy living for her family and friends.

 

In 2017, Natalie reached a plateau with her fitness and decided to join the Rock Fitness team. The training program at Rock Fitness provided a whole new set of goals to achieve...ultimately taking her fitness to the next level. She's passionate about the Rock Fitness community and has been helping members reach their fitness goals since becoming part of the coaching staff in 2018.

Coach Jill Headshot_JPG.webp

Coach 

Jill nieto

Jill is a Cardiac Tech at a local hospital and a mother to a 7 year old girl. She played many sports, but mainly soccer throughout childhood into adulthood. She lives an active lifestyle and enjoys learning and indulging in functional fitness, nutrition and personal development. When she is not in the gym you can find her spending time with family, exploring the outdoors, fishing, hiking, mountain biking, or diving deep into books and podcasts.


Jill joined Rock Fitness in 2019, as she found herself wanting more out of fitness, rather than the inconsistent traditional gym regimen. Her love for fitness and a healthy lifestyle grew into a passion and  has a desire to share that with others. Within that year, she made many habit changes and made it a goal to get her Level 1 CrossFit Trainer Certificate and make her ambition of coaching become a reality.


She believes fitness is the essence of overall wellness. Jill says, the community, the philosophy behind functional fitness, and the growth mindset you can gain will change your life for the better, not only physically, but mentally. 


Jill thrives on seeing others overcoming adversity and challenging themselves, getting the mental and physical gains they always wanted, or didn't believe they can achieve. Celebrating all victories and milestones along the way. Any knowledge, tools, support or encouragement she can give to help others achieve and reach their fitness and nutrition goals or a better self, is why she made the leap into coaching. Even if it's to escape the daily stressors of life, or if it's your hour of daily self care, if she can make that one of the best hours of your day, she believes she did her job.
