What Our CLients Are Saying
As a senior, I know how important it is to maintain muscle mass. I began working with Kim two years ago. Over that time, I’ve increased both my muscle mass and the bone density in my lumbar spine. Kim creates workouts specific to my needs. Her knowledge, experience, and positive encouragement make her a perfect fitness coach.

Kimberly has been my personal trainer for about a year. Prior to that she was my wife’s trainer for two years. She works with me three days a week for an hour. I am almost 90 years old, and working with Kimberly keeps me moving. The sessions include weight training and balance exercises which are very important at my age. Kimberly is very personable and professional. She is very easy to work with and I highly recommend her.
— Dick
After having worked with another trainer and often aggravating my bulged disc after personal training sessions, I entered our sessions thinking I’d just use up the ones I’d bought and be done. But Kristen has done such a great job identifying areas of weakness and starting with small but challenging exercises — I can feel the difference after just a couple sessions. She keeps my schedule in mind, reaches out when she has openings, and does a great job managing time and keeping exercises on track. She’s made me reconsider continuing my sessions — and I plan to buy more.

I love working with Kristen and would highly recommend her to anyone looking for a warm, experienced, and professional personal trainer. I was looking for a trainer who was a good mix of experience and presence — and that’s exactly what I found with Kristen. She took time to get to know me and my goals, and she’s helped me not only meet them but also find confidence in the gym. I highly recommend her to anyone looking to take their fitness goals seriously!

I highly recommend Kimberly as a trainer! After many months of poor mobility and hip surgery, she has me stronger, more flexible, and more confident than ever. Her expertise and personalized approach ensure safe, effective progress, and her patience and encouragement make all the difference. Plus we laugh along the way. Thanks to Kimberly, I’m moving better than ever and feeling stronger than I thought possible. She’s truly exceptional at what she does, and I’m so grateful for her support!

I started working with Kimberly in September 2022, and it’s one of the best health decisions I’ve made. In my mid-60s, I’m stronger, more balanced, and building muscle when most people expect the opposite. I’m not naturally athletic or self-motivated, which is why I was surprised by how much I enjoy training with Kimberly. Her programs are thoughtful, progressive, and never boring—and I feel safe and supported every step of the way. Working with Kimberly has given me real confidence in how I’m aging and the future of my health.
— Peg
I started with KDM Fitness in early 2023 because I was losing strength and worried about my ability to move well as I aged. Weight training was completely new to me. With Kimberly’s guidance, I’ve regained strength and confidence—I can get up off the floor easily, handle stairs, and carry things without hesitation. My bone density has even improved, and I can now do sit-ups, which I never thought possible. Investing in my long-term health has become non-negotiable.
— Jan
I have been “training” on and off for years on my own, never understanding why I never felt stronger. I came to Kristen in hopes of finding an answer and to gain a better understanding of what exercises I should group together on my gym days to actually gain momentum in my training. Kristen has gone above and beyond in helping me gain confidence, knowledge, and strength! Kristen helped me understand that even the smallest tweaks in form can change an exercise immensely. Kristen also takes great pride in trying to help with any aches and pains that a person experiences and her willingness to continue to research ways to help is more than I could have ever asked for in a trainer!
