ABOUT ME

Duncan
Owner/Lead Trainer, B.S in Health Science: Health Promotion, ACSM-CPT, CSCS, Pre-Post Natal Certified
Fitness is the most essential priority in my life. I’ve learned that in order to show up for the people that matter the most to me, showing up for myself is essential. I prefer to lead my example, be a practitioner of the art of training. Making health and fitness a top priority has a huge impact on other important areas of our life. That impact helps get and keep things in alignment. My clients can trust me to be a resource in their life. They can trust that I care about them and the relationship we build together. I am all in with them every step of the way, and I will be all in for you too.

I’ve trained with Duncan throughout my second pregnancy. It has felt great getting a solid workout in each week throughout my pregnancy, allowing me to continue to feel strong and fit. He has thoughtfully curated the workouts to continue to push me but also to focus on mobility exercises that alleviate the aches and pains of pregnancy and will prepare me for a smoother childbirth and recovery. He is always open to adjusting our sessions and specific exercises to meet me where I am. He has a kind and thoughtful way of engaging with his clients and is a joy to be around.

Duncan is extremely professional and a pleasure to work with. He cares to understand your goals and makes sure your needs are being taken into consideration. He is motivational and takes the time to walk you through the excersize which is exactly what I said I was looking for. I am very happy I finally found a trainer that I enjoy working with and am already feeling stronger.

Duncan and I have been training together for the last 9 months, and it’s truly the best thing I’ve ever done. Duncan is a tough but fair and patient coach, and he has shown me that I’m far stronger and more capable than I ever thought I was. He has also made working out enjoyable for me again, and I look forward to our sessions every week. On top of being an incredible coach, he’s also extremely punctual, organized, and always manages to squeeze me in when I have to change our usual schedule. I’m grateful to Duncan for helping me build a strong foundation, and I’d absolutely recommend him to anyone looking to grow/build upon their fitness skills!

I worked with Duncan for the second and third trimester of my first pregnancy and had an A+ experience. Duncan is incredibly talented - he comes up with creative, challenging, and fun workouts that make you feel better physically and mentally. And, he is a really positive person who is easy to be around week after week. He is also an incredibly timely and organized person which helps make fitting sessions into busy schedules much easier. I genuinely enjoyed working out with Duncan weekly during my second and third trimester (and soon post-partum!) and give him a strong positive review.

The best trainer!! I highly recommend Keen Personal Training! He’s incredibly knowledgeable about all different exercises (including my favorite pilates) and has given me great alternatives when I’ve had an injury. His workouts are unique and always challenging, and I've definitely gotten so much stronger since working with him. He’s great at tailoring sessions to my needs and always knows exactly how to keep me progressing.

Coach Duncan has been the one consistent thing in my life for the better part of the last year and a half. over this period of time i’ve gotten to know myself deeper than ever. beyond an emphasis on form and technique, Coach Duncan has guided me through my journey in investing in my physical health - on another level. the philosophies that I gleaned from Coach Duncan (which he implements himself) will stay with me forever. Coach truly downloads and installs what’s necessary in your regimen and (with a magnifying glass) ensures that it is implemented properly. i’m very glad I found Coach Duncan; the work we’ve done together has rendered a greater version of myself!
