About
I provide personal fitness coaching for clients in Kailua, Hawaii, drawing on 24 years of experience and 16 years in business as a dedicated solo coach. My focus is on high-quality movement and biomechanics, so you learn to move better, not just work harder.
Clients often say they leave sessions feeling “put back together” and “like they’ve just had a massage.” I design each session with measured intensity to help you feel invigorated, strong, and more connected to every part of your body.
I truly value the relationships I build with my clients and love supporting them in changing their lives and their experience of their bodies. If you’re ready for thoughtful, personalized coaching, I’d be honored and stoked to work with you.

I've been working with Trevor for a month now, and can't speak highly enough about him and my experience!
I chose him because I have some back issues and he is very knowledgeable in that area.
He has helped me already so much, not only with weights and exercise, but more importantly his approach on mind, body and soul. The breath work , and fascia alone has changed my entire fitness approach.
I Highly recommend Trevor

Trevor is an outstanding professional and an even better person. His knowledge is what initially led me to choose him as my personal trainer, and his personalized, compassionate approach is what kept me coming back.
When I first started training with him, I was dealing with knee pain and sciatic nerve issues that only seemed to get worse with exercise. He always respected my limitations and designed my training around proper biomechanics and functional movement.
Today, I’m pain-free and have much greater body awareness. I highly recommend Trevor to anyone looking for a knowledgeable, caring, and highly skilled personal trainer.

Trevor ranks above other top trainers I’ve worked with over the decades. For more than a year, I’ve been driving from town to Kailua to train with him.
The program he designed takes into account the whole picture, my goals, where I am on a given day. We started with traditional strength training, then transitioned to mostly functional training. He has me use cables, Swiss ball, medicine ball, free weights, body weight, bands, and more. He breaks down complicated moves, sets up progressions, and calibrates unerringly how to push me to higher levels. I feel safe, end every session feeling well-exercised, and am ready to go again the next day.
Trevor brings to his work broad and deep professional knowledge, strong teaching skills, and a passion and delight to help each client be all they can be. He’s a coach in the truest and best sense of the word.

My husband and I are nearly 80 and have been training at our home, with Trevor three mornings a week for 20 years !! Trevor’s commitment has paid health dividends beyond our wildest dreams. Trevor has built our strength, resilience and flexibility as we have aged and our workouts are tailored to our needs and each day is never the same! Trevor‘s understanding of the human body truly pays off when we have an unusual ache – he knows the human body and uses physical therapy to stretch our complaints away. As a result neither of us have had any need for orthopedic intervention. By investing in Trevor, we are able to stay physically active and enjoy staying “young” as we age. Trevor is truly gifted in what he does and has made a significant contribution to our quality of life.

Trevor is a wizard. The most detail oriented, keenly observant, thoroughly knowledgeable coach I have ever worked with in 25+ years of serious sports and fitness training, combined with one of the most thoughtful, empathetic, open-hearted individuals ever. Most trainers can give you a workout; only a very small handful can train you to get stronger and healthier by learning how to heal your body, fix dysfunctional movements, and unlock real athletic potential in anyone. Trevor trains everyone from world class athletes to elderly clients trying to stay mobile, and meets everyone where they are in their fitness journey. This is the one coach I would train with forever.
