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.

I've been doing strength training with Jennifer Dietrick for over a year now and it's one of the best decisions I've ever made. She has an expert's understanding of anatomy and fitness and she's always willing to explain her methods and offer advice if asked. I had never worked out at this level before so I wasn't totally sure what to expect when I started, but Jennifer is great at adapting to what each client needs and wants. If you're looking for a knowledgeable and reliable trainer with a strong sense of professionalism, I highly recommend her!

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 personaltrainer, 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!

When I first met Jennifer near the end of last year, I was morbidly obese. I had gained about 50 pounds, and for two years could not get rid of them. The only thing I could do was call a professional. I was hesitant because I have had a lot of experience with personaltrainers. Each one had their own approach, and I started feeling the ‘personal’ in personaltraining was more about the trainer’s personal philosophies, and less about me. I would cancel more than half the sessions and dread the sessions I was present for. And I never lost weight!!!!!
Jennifer was the first trainer to listen to my needs. I told her about my fears, and she designed a program just for me. And I started feeling very differently about my workouts. In fact, I started looking forward to them. So much so, that a couple months ago I asked Jen if we could go from 2 to 3 sessions a week. Jennifer has taught me important dietary changes as well. She works without being condescending or forceful. She is exactly the perfect personaltrainer for me. But I also know that she caters to every client according to their personal needs.
I look good, feel good, asthma is gone, bp is normal, heart rate is lowered, and my self-esteem is back. I just weighed myself before writing this. 27 pounds off as of this morning. Thank you, Jennifer, for bringing this hot lady back. I’m off to conquer the world. ;)

My 6 ACE certifications are personal trainer, health coach, orthopedic exercise specialist, fitness nutrition specialist, sports performance specialist, and functional training specialist.
