I’ve been training with Mark at Gateway CrossFit for about five years now, and he's not only an incredible coach, but also a great friend. The community is amazing. I’ve met many awesome people through CrossFit here. Mark puts together specialized, thoughtfully designed training that really fits the needs. We even have fun gym events from time to time! I’m super excited that he’s moved to a new, larger facility :) Highly recommend!

Mark really understands his clients and works to keep them healthy and on the go. He customizes workouts for specific needs and capabilities. Don't be afraid to start with a trainer - it will make a lifetime of difference (if it's Mark 😊).

Mark is a great trainer and is very good at creating workouts that are challenging and manageable for any level of experience. Gateway is an amazing space with great people and awesome dogs to help you with your workouts.

My husband and I have been working out with Mark for nearly three years. He is an amazing trainer, motivator and friend. After only a few months of training with Mark, I noticed significant changes in my strength and stamina, and he effectively increases weights and intensity over time. Our workouts are always different, which keeps me interested and engaged even after years of working together. Reach out to Mark if you are looking for a knowledgeable and results-oriented trainer!

Mark meets you where you are and then pushes you to get better. Adjusts the workout for where you are at, and allows you to recover and get stronger. --- Also he is flexible with schedules - when work or life gets in the way.

Highly Knowledgeable, Adaptable, and Results-DrivenIf you are looking for a trainer who understands biomechanics, functional mobility, and tailored strength training, Mark is the best in the business. Our family has been training with him for six years, spanning three generations—including myself (47), my teenage daughter (18), and my father (75). His ability to program effectively for all age groups is incredible.He has coached me through recovery from injuries during my training for an Ironman 70.3, provided excellent nutritional guidance, and created travel-friendly workouts to keep me consistent when I'm on the road for work. Mark is an absolute professional who genuinely cares about his clients' performance, health, and longevity. Five stars all the way.

I have been training with Mark for 3 years and I have gained so much strength! His training has also helped me majorly reduce my back and joint pain. He has flexible scheduling and he is just fun to work out with!!! I can’t recommend him enough.

I have trained with Mark for 12 years.He has kept me strong through stress, strains, everyday life and even while I underwent Chemotherapy. I didn’t miss a session.He is outstanding at what he does. I had a low back issue: primary care, neurologist and physical therapist without relief and it was Mark who figured it out. His knowledge of muscle work and movement led to figuring out the source.The strengthening and cardiovascular workouts we do translate into everyday life such as lifting and moving in your day to day life.I think this is money well spent to maintain your health and mobility.

I have trained with Mark Whitener for 8 years now. I am stronger and more fit than I have ever been. He is incredibly skilled and patient in his instruction. I particularly appreciate his meticulous attention to detail, proper form, and natural safe mechanical movements. Mark helps clients from an entire range of premiere young athletes to older clients staying strong and balanced as they age. He personally guided me judiciously and compassionately through a health issue. And I’ve seen him do the same for other clients who can keep exercising safely through life challenges. Mark is an amazing person with profound integrity, genuine concern for and faith in his clients, and a sense of humor that makes the time fly. Training is fun and effective. I am extremely grateful for how much he has helped me.
