About

I help people think and be healthy! I assess each client to determine how best to improve their overall health and fitness. I look at all of their current habits in every area of their life to aid them in reaching their fitness goals. I train clients at their homes and I specialize in reshaping your body while building strength. Most of my clientele are business professionals looking to be fit, strong, and in optimal health. I'm also pet friendly and look forward to meeting your adorable animals. I am a Functional Training Specialist and Orthopedic Exercise Specialist and have plenty of experience working with clients requiring training programs to work around any ailments or injuries. As a former Anatomy and Physiology teacher, I have always been fascinated with the human body and would love to share my knowledge with you! Seeing the excitement of clients when they witness their progress and/or goals gives me great satisfaction. I enjoy guiding clients to help them change their outlook on health and fitness to maintain a lifelong journey of health. I also offer self-defense and jiu jitsu lessons for both one-on-one and group settings. My martial arts background is a black belt in jiu jitsu and I have been training and competing for the past 13 yrs. I have also been an instructor for 7 years. This martial art uses skills ideal for a smaller opponent against someone larger which is very beneficial for women.

Jen is an exceptional trainer and an absolute well of knowledge. She’s an athlete and a teacher, with a lifelong commitment to health and fitness that truly shows. I joke that she’s a walking billboard, she’s vibrant, strong, and the definition of vitality. What really sets Jen apart is how deeply she understands women’s bodies, especially as we move through different stages of life. She knows how to support strength, metabolism, and overall well-being through a smart balance of movement, nutrition, and consistency. She’s kind, warm, and genuinely lovely, but she also knows exactly when and how to push you. Every session feels intentional and supportive, with the right mix of focus, encouragement, and ease. Jen is incredibly attentive to form and safety, thoughtful about progress, and deeply knowledgeable when it comes to nutrition and holistic wellness. You can expect a clear program, structured sets, precise corrections, and someone who always shows up on time and prepared.

Since working with Jen Dietrick, I have more strength, physically and emotionally; I am toned; I have more energy; my body has changed. Before we started working together, I was overweight, my blood pressure and cholesterol were so high that I was in danger of facing daily meds. But since working with her my numbers are good, my health has been steady, and I am strong. As Jen is fond of saying "you can do more than you think," and I have been doing much more than I ever thought possible . . .because of JEN!"

After a long-time search for a personal trainer, one that would put my fitness in alignment with my health and jiu-jitsu goals, I am so glad to have found Jen. Not only have I been able to stay consistent on my path to a better quality of life, I feel confident and grateful to know that I have someone that will help me maintain and increase my fitness goals and show me the tools so can do it for myself for the rest of my life. Her patience and encouragement is never intimidating yet she is the no-nonsense type that is very firm and increases the challenge accordingly. She makes herself available to answer all my questions and customizes my plan to fit my needs. She is very knowledgeable in all things fitness. What I like most of all is how she corrected my mindset, how I see and talk about myself and my body, and integrates a proper attitude that sets me up for success. I love how she emphasizes the importance of maintaining good form to minimize injury and maximize efficiency. If you're looking for long-term results that will transform your mind and body, look no further. Jen is truly a wonder! She has made me look forward to exercising and removed any intimidation I had when thinking about weight-training and lifting. I look forward to training with her for as long as possible!

FAQs

What should the customer know about your pricing (e.g., discounts, fees)?
I offer a 15-minute free consultation via phone before you begin training. My rate varies depending on location and number of times you train per week.
What is your typical process for working with a new customer?
I offer a 15-minute free phone consultation to discuss the client's health and fitness goals along with their past history. During the consultation is also a great opportunity for the client to determine if I am the right fit as your personal trainer. I discuss my methods and my individualized goals for you and the upcoming process. I have the client complete forms about their history and goals. We discuss schedules and proceed from there.
What education and/or training do you have that relates to your work?
My 6 ACE certifications are personal trainer, health coach, orthopedic exercise specialist, fitness nutrition specialist, sports performance specialist, and functional training specialist. I am a former Anatomy and Physiology teacher and hold a B.S. in Secondary Education for Biology. I have a sports background in gymnastics, fitness competitions, and jiu jitsu. I have also coached in all three of these sports.
