    Certified Personal Trainer

    Certifications/College Degree(s): BA Psychology, MA Anthropology, ACE Personal Trainer since 2002, Sample certifications; YMCA Group Exercise Instructor, TRX Level 1, YMCA Strength & Conditioning Course Teacher, Yoga for Personal Training. About: My journey in Fitness began in weightlifting several decades ago, as a way to alter lifestyle habits, and the direction of my life. With regular dedication and dramatic results, it wasn't long before others in the gym, including my friends, began to ask for training tips, information or help. Several years later I began teaching classes and loved it! With thousands of hours of training, teaching and managing fitness centers under my belt, regular examples of Client success include; 100 pound weight loss, training for 100 mile century bike races, and no longer needing medications due to consistent and progressive changes in diet and exercise. My specialties are helping clients regain strength and health in midlife, working with women's health issues, weight loss, flexibility, older adult exercise, adaptive fitness, pre and post rehab for knees and hips, as well as recovery from a traumatic life event through body movement. My approach is to consider all factors, such as time management, competing demands of family or community, to listen and watch attentively, have fun, and respect the client's inherent wisdom as the steward of their body. To better address providing guidance in changing lifestyle habits, my scope of practice is expanding to include comprehensive Health and Wellness Coaching. Teaching corporate classes for GymGuyz Marin is such a privilege to help students make positive changes in their wellbeing and quality of their lives!

  • Leslie

    GYMGUYZ Owner

    Leslie Dempsey San Rafael, California Marin County “Feel the fear, do it anyway”- Jo-Ann Houston shared this quote at GG training After I had my two children, I was on a mission to get back in shape. I started going into the gym and my husband Brain helped my with programming for weight loss and muscle building. I was also focused on nutrition. I got in the best shape in my life and started empowering others to do the same! I have played all types of sports but found my passion in Dance. I am trained in ballet, tap, jazz, hip hop and modern dance. Last year I found a great passion in Pole Fitness and now I train twice a week! My mission is to build a business that empowers our clients to change their lives and be the healthiest they can be! We are all about enhancing our clients lives by motivating them, holding them accountable and providing support in them most loving and compassionate way. My husband Brian, is a co owner and while he has a full time job in the staffing and recruiting industry, he is a constant help and support in operating GYMGUYZ! He is my rock and his ambition and energy is an inspiration to me. On June 17th we are celebrating our 11 year wedding anniversary and 12 years together! He loves mountain biking and swimming. Brian is the most amazing father to our children and the greatest partner a woman can ask for. My favorite thing about him is his unwavering loyalty to me, our family and the life we have built together. My daughter Layla is about to be 7 years old and she loves art, reading, swimming, gymnastics and dance. Her athleticism constantly surprises me and her kindness towards others makes me beam with pride. For being so young she has such a strong sense of responsibility and need to do what is right. Layla is always ready for the next adventure, loves to travel, loves to be around the ones she loves and she is so intelligent. My son Jack will be 4 in September and he loves swimming, and building and creating things. He has such an outgoing personality and his humor makes me laugh out loud everyday! While he has strong opinions he is so loving and affectionate. In being a parent, what I most proud of is the value my children place on our family unity! My son is always talking about how we are a team and my daughter places the utmost emphasis on our family bond. I am a certified fitness trainer and plan on getting a certification on nutrition as well!
