OUR TRAINERS

  • Nick Walejeski (Owner)

    NCSF, NESTA, NASM, USAT (USA Triathlon), TRX, Bachelors in Psychology,

    My name is Nicholas Walejeski and I have been involved in the fitness industry since 2004. I have group and individual clientele ranging from college level athletes looking to increase sports performance, to older populations looking to increase quality of life. I have a passion for the fitness and wellness industry and believe that in order to successfully change one’s fitness lifestyle, one’s current psychological abilities must be challenged and changed as well. I have a Bachelor's degree in Psychology from Cal State San Marcos and am currently certified from multiple nationally recognized personal training certifications (NCSF, NESTA, NASM).

    I believe in a holistic approach to fitness and wellness where my clients not only re-shape their bodies, but they re-shape their thoughts and attitudes towards fitness. I have competed in college level volleyball and have coached Men's Varsity Volleyball at Davis High School. I am experienced in developing personalized weight loss programs, resistance training programs, hypertrophy training, core training, polymetrics, functional training, post-injury programming, and special population training. I have been leading indoor and outdoor boot camps for over 5 years now and am continually impressed by the repeatedly developing abilities of my participants. Triathlon training has developed into one of my most successful fitness programs where people develop into a brand new sport and build lifetime friendships with fellow competitors.

    I have been leading the triTRAINed triathlon training program for the past 4 years in Davis. The 2014 season will be my 5th year coaching the team. Each year we grow stronger and represent deeper within the triathlon community. We are a goal oriented program and are proud to train a wide range of athletes; from first timers looking to complete their first triathlon, to consistent top three podium finishers. I hold a Level 1 USAT triathlon certification. Please take a minute to read our success stories in the Before and After section.

    I like to bring a fun and creative edge to my fitness programs where your current levels of fitness are challenged in new and exciting ways. My passion for fitness and wellness is contagious and will become ever apparent as I guide you to your fitness and wellness goals the quickest and safest ways possible.

  • Thomas Gojkovich

    B.A. in Sociology, Certification: American Council on Exercise (ACE), DHS Assistant Varsity Baseball Coach, Former Collegiate Baseball Player: College of Marin, Sonoma State University

    Fitness has always been a big part of my life. Growing up in Davis, I was an avid baseball, basketball and soccer player and loved the thrill of competitive sports. As the youngest of five boys, playing outside with my brothers was an everyday activity and my parents encouraged us in everything we chose to do. As I went through high school and into college, I realized that baseball was my true love. To excel in my passion, I needed to focus on getting into shape, and that meant hitting the gym. During my junior year of high school I started strength training, and working on my cardiovascular fitness and I was hooked. The way that exercising made me feel was unmatched by any other aspect of my life. When I got to college, I realized that my 6’1”, 175lb frame could not compete with the 6’4”, 220lb men the baseball field. I was determined to take my training to the next level, and by the end of the year I had gained considerable strength and endurance, and was ready to compete. I am so thankful that I was surrounded by people who took part in encouraging me in my fitness journey.

    My Sociology degree from Sonoma State has given me a wide perspective of different cultures and societies, along with a well-rounded thought process. However, at this point in my life, my calling is health and fitness. Every day I realize that fitness is my true passion. Passing on the vast number of advantages that an active lifestyle has to offer gives me an unmatched high. I live my life in a way that promotes health and longevity and I encourage others to do the same. I enjoy helping others achieve their goals, whatever those may be, by providing a fun and comfortable fitness atmosphere. Sometimes life makes the road tough, but when it does, I will be there to help you persevere. I welcome challenges in all shapes and sizes. I encourage you to follow your passion, develop goals, and reach for things that you thought were out of your reach. Let’s get fit and let’s do it together!

  • Derek Haff

    NASM Certified Trainer | B.S., Business Administration

    Are you looking to lose weight, get fit, or increase the intensity of your training regimen but perhaps need a little guidance, encouragement, or motivation? My name is Derek Haff, and I am eager to help you meet all your fitness objectives. While I am new to personal training in the professional sense, physical fitness has been at the center of my daily activities for as long as I can remember, and it has always been among the top priorities of my life. I have been involved in many aspects of athletics, having played football for many years as a youth, softball as a young adult, and have been studying the art of karate for the last couple years. Throughout, I have been highly devoted to all aspects of fitness, including weight training, aerobic exercise, and nutrition. My family has been members of the various manifestations of Get Fit Davis for about 25 years now; in fact, from the time that it first opened, and I have been working out here since I was 14 years old.

    I earned my bachelor’s degree in Entrepreneurship from Sacramento State University in 2015 and I have decided to devote my time and energy to the thing that I am most passionate about: fitness. Towards that end I concentrated my efforts during my final semester of college to obtaining my N.A.S.M. certification as a physical trainer. Although some might say that physical fitness is not a career, those who dedicate their lives to fitness know that nothing is further from the truth. Given the aging population and the obesity epidemic, fitness is clearly an area with unbounded potential and opportunity. Devoting myself to help others achieve their fitness goals gives my life purpose beyond what could typically be achieved in the business environment.

    Whatever your fitness goals may be, I can assure you that as your personal trainer, achieving those goals would be my highest priority. Your success will give me great personal satisfaction, and I will leave no stone unturned in making sure you become as fit as you want to be. I hope that my enthusiasm for fitness will be contagious, and you will embrace physical fitness as your main focus in life as I have.

  • Jeffery Roy

    Certified Personal Trainer and Senior Fitness Specialist, National Academy of Sports Medicine (NASM)

    My clients, or as I like to say “Team Members”, can range from a person just beginning their journey in health, to someone increasing mobility in daily movement and shedding pounds, to regular and “Masters” or Senior athletes who wish to go to the next level.

    After review and goal setting together, we start by emphasizing proper technique and strong foundation in balance and movement. We then build endurance and strength, with the options of power, speed, agility and quickness. We are always doing mini evaluations or “Tune –Ups,” whether it is going after extra weight loss (I lost 60 lbs), gaining confidence in daily movement, firming and toning, training or pursuing a specific sporting event, or even just having fun achieving “The Positive Body” that is within you in a safe and comfortable environment.

    I would like the opportunity to be your “Team Member” in Certified Personal Training. After a successful career as a Professional Winemaker and Certified Wine Sommelier, I enjoy an integrated health and a well-being lifestyle using appropriate, successful exercise to increase and improve the quality of your “Lifespan AND Health-Span.”

  • Bob Randel

    • Bachelor of Arts in Exercise Science
    • Certified Strength & Conditioning Specialist
    • Certified Personal Trainer

    I came to Davis in 1977 to attend UCD and study Exercise Science and started working as a personal trainer and conditioning coach soon after graduating. I have 30 plus years experience and enjoy working with all ability levels. As we work on proper form for all exercises I find that there are usually some mobility issues that need to be addressed so that proper form can be attained. I like to think of training as pre-habilitation and building up the entire body through a variety of exercises and modalities to keep things interesting for us both.

    I also work part-time at UC Davis as a personal trainer for the Workstrong program, training employees who have been on workman's comp.

    Running and sports participation has been in my life since I was a young boy. I have competitive and coaching experience with running, soccer, basketball, and baseball. When I was younger I competed in triathlons and ran races from 5k to marathons and when I turned 50 I started running 50k trail runs. I will be coaching a Get Fit Running Club so let me know if you are interested in joining us for some great conditioning workouts. I would really enjoy working with you as your personal trainer or running coach to help you reach your health and fitness goals.

  • Luciana Castro

    ACE Certified Personal Trainer

    I am an ACE certified personal trainer and a fitness enthusiast. I started when I was 5 years old by taking jazz dance classes and did it for 10 years. During high school and college, resistance training became an alternative to keep me fit and physically active in a busy daily routine as I could never stop exercising because I love the energy level it brings to me. I also trained to increase cardio and muscle endurance, participated in weight loss program, and became passionate about functional and HIIT workouts (at home and in group). More recently, I became interested in powerlifting and weightlifting techniques.

    My degrees in Mechanical Engineering (I’m an UC Davis alumna) help me to understand the mechanics and kinetics of the body, which induce me in prioritizing form in my trainings, avoiding injuries. After all, what really changed my life completely were my two kids. Now I feel I understand even more how important it is to live a healthy lifestyle to be able to enjoy them at best and give them a good example. Based on my life experiences, I decided to shift gears from my engineering career to become a fitness professional. Now I specialize in weight loss programs, improve activities of daily living in special population, fitness for health and wellness, and helping new moms that want to go back to their fitness life or want to start one, but doesn’t know how to. However, if anyone needs help achieving any fitness goals, I am always up for the challenge.
