Updated review: I updated this review to repeat my appreciation to One on One for the results that keep me doing the things I love. I also want to comment on... read more the absurd and malicious review that Neda M. posted, and the patient and resounding response to her fabrication. Neda, do your colleagues at AESO know that you treat people and businesses who are trying to help you with arrogance, contempt, and lies? They will. I have now been a client for over 20 years, and give Sandra, Codrut, and the entire team a resounding thumbs up! At 72, I can do everything I could in my 30s. I ski, hike, swim, kayak, and travel extensively to remote natural areas. I also have the energy to sit on four boards. One on One helped make and keep me fit, they nutritionally educated me, and supported me in my goals. This is a very high performing team who care about their clients.

June 28, 2024Sandra and her team are the best in the business. I suffered all my life with back pain and then for a decade with pelvic symphisis. I tried everything I... read more could for years to get into better shape and solve my back and pelvic issues including yoga, HIIT classes, and more. The pain was getting worse year over year. Then I was introduced to One on One. My trainer is an expert, has a kinesiology background, and knows how to build on my overall fitness and strength overtime without exacerbating my condition. I'm coming up on two years with One on One. This is the longest program I've stuck with and it's because of the support and expert guidance I receive. One on One has transformed my body and mind. I can't thank them enough!

June 28, 2024Several years ago I had a bad fall - the kind that doesn't break bones that heal, but rather tears and pulls of muscles and ligaments, and cartlidges doing cartwheels.... read more Recovery had been long and slow, but after a referral from my physio to see Sandra, my rehab started to take a significant turn for the better. She assigned me to Nathan, who seems to specialize in injury recovery (and he has been able tolerate my difficult schedule and sometimes significant whining :). I have been working with them for over a year now, and since day one their understanding and compassionate care has been second to none. The history of this place and their trainers is one of dedication and success... I have spoken with other clients and there is so much respect for their work and their complete commitment to their clients. I feel for the first time in years that I am truly recovering. Other therapists kept telling me what I cannot do... Sandra and Nathan continue to inspire me to go above and beyond what I thought my limitations were. Thank God for these guys... and 35 years of folks like me would form a parade to demonstrate it. THANK YOU One on One. What you do, really matters.

June 28, 2024I have been a client at One on One for over a year now and I cannot begin to thank Sandra and Nathan enough for all of their amazing advice... read more and support. I never feel judged or pushed into something I don't want to do or don't feel comfortable trying. Sandra and her entire team are absolutely wonderful people who truly care about each of their clients. I have never enjoyed weight training or thought it was for me, but I truly look forward to my two days a week at One on One. I am listened to, encouraged, and challenged in all the best ways to meet my goals - primarily of becoming stronger for everyday tasks and more fit to take on new ones, and (in a few years) of entering my 60's and beyond as a strong and fit senior who can continue to enjoy my family, friends, and the beautiful outdoors. I look forward to being a One on One client for years to come.

June 28, 2024Sandra (owner) and Nathan (trainer) are truly wonderful. Prior to training here, I had hated exercising and had never worked out before. I started with them near the end of... read more the summer last year, so about 8 months ago. But since working with them I have become way more motivated, and have learned to enjoy working out now, and continue to strength train regularly and consistently outside of our sessions. They tailor to your goals and encourage and challenge you to progress and build confidence. In my case, I’m a woman in my 30s who is already petite but wants to be leaner and I’ve seen results since I started. During our training together, I enjoy being reminded which muscles I should be engaging during the exercises and ensuring proper form. Thank you Sandra and Nathan!
Janine Fung
April 8, 2024Sandra and Nathan are fantastic and I would highly recommend trying out One on One if you are looking for a personal trainer. I came to One on One having never... read more worked out before and ten plus years working a job that had me seated for 12+ hours a day. Needless to say, I was a little fearful of training, but Nathan was *excellent* in meeting me where I was at. After six months, I felt like a whole new person. In addition to that, Nathan referred me to a physiotherapist he knew who specialized in necks. Between Nathan and the physiotherapist, I was able to fix a painful problem I'd been trying to fix with various other providers for over a decade. A+

I started working with them on personal training and nutrition in January, and I’ve lost a good amount of fat and put... read more on a fair amount of muscle since I started at One-on-One; from day one, they heard me, saw me, and supported me to achieve my goals. I had never been someone who went to the gym before or felt comfortable working out, and I felt like I lacked much of the education to know how to work out properly. With the support from One-on-One, I’ve learned so much, and I’m motivated to learn even more as we continue working together! They’ve helped me hit my goals for my upcoming wedding and also my overall dream to become a healthier, stronger, and happier person. They support sustainable health and fitness for the long term, and that is a gift like no other. I highly recommend working with them.
