As a former collegiate athlete I developed the discipline of exercise and nutrition, to maintain a level ofFitness. But as I aged, I discovered that the exercise and nutrition that I apply for success at a younger man no longer works for what I need for today . I started Bodybuilding at the age of 50 first competition at 51 last competition age 70. I’m now 72 and my exercise style has changed,my metabolism changed and my endurance has changed, so I needed to make the adjustments to live a quality life . Now l work for functional movements, flexibility and strength. If you’re between the age of 50 to 80 you will find a motivating environment at PDX MUSCLE . No intimidation, just motivation and encouragement.

My journey in fitness began with a personal need for both physical and mental transformation. Over time, I discovered that training doesn’t just sculpt your body—it forges character, discipline, and confidence. Today, as a personal trainer my mission is to help you build not only the body of your dreams but also an unbreakable mindset you can apply to every area of your life.
In addition to being a personal trainer, I’m also a certified nutrition coach, which allows me to offer complete guidance in both training and nutrition. This gives me the tools to support you fully throughout your transformation—from creating effective workout routines to designing personalized nutritional strategies based on your goals.
I specialize in muscle building, fat loss, and total body transformation. I’ve experienced both ends of the journey myself—I know what it’s like to want to lose weight and also what it takes to gain size. That personal experience helps me connect authentically with my clients and guide them with empathy, creativity, and real results.
I work with people who are ready to give 100%, who have a burning desire to improve, and who understand that real change begins from within. My approach is not just physical, but also mental and emotional. I design programs that adapt to your level, lifestyle, and objectives—regardless of your age or fitness experience.
As a coach, I see myself as complete. In every session, I challenge you to grow, push harder, and become the best version of yourself. I’m not looking for perfect bodies—I’m looking for strong minds, committed individuals, and people ready to conquer anythi
