He works to build connections with clients, teaching movements and techniques that are sustainable over time, and adaptable to any individual or situation. He will help you get stronger and move better, give you mental and physical principles that will help guide you for a lifetime, and—maybe most importantly—remind you that while we’re serious about our work, we don’t have to take ourselves too seriously!

Customer Testimonials

  • "Training at Leap Fitness has been the best decision I’ve ever made for my health. After a busy year without regular exercise, I was determined to make some lifestyle changes, reclaim my fitness, and gain a sense of overall wellbeing. From day one, Ronan has provided clear and tailored guidance that extends way beyond just exercise - not only has he helped me build strength and mobility, but he’s worked with me on a nutrition plan, actively addressed old injuries, and given me a more integrated, 360 view of my health. Gabriel on the team has shared brilliant advice on heavy lifting, and James is an extraordinary bodyworker who shares insightful feedback on my body’s mechanics with Ronan to help inform my program. In addition to being absolute masters of their craft, Ronan and his team are also kind, patient, and fun. Leap is such a welcoming and energizing place to get fitter and feel better."

    Aaron B.

  • “I have four kids and have been working out with Ronan, before pregnancies, during and after. I can not express how blessed I am to have such a wonderful trainer. He is always available for feedback, training, and support. Leap Fitness is the best investment for a healthy lifestyle.”

    Dokleida

  • “I have been training with Gabriel for over seven years, several times a week. He is very experienced in various methods of fitness and tailors his approach to the needs of his clients. As someone with chronic back issues, I appreciate the patience and care Gabriel takes to ensure I am using the correct form and appropriate weight. At 53 years old I have never been stronger or in better shape. My back is strong as a result of the technique and practice Gabriel has instilled.”

    Jonathan B.

  • “Wow, I have only been working with Jazmin for 6 weeks. Through her guidance, I already have lost 6 lbs. I am feeling stronger and more stable. My mobility and range of motion have improved so much. I can finally squat all the way to the floor which I could never do. I am so psyched to find a personal trainer who can attend to all my health needs and she clearly knows what she is doing. Looking forward to continuous improvement and hitting new goals.”

    Conal

  • “Ronan is the ABSOLUTE BEST!! With a vast knowledge, good communication skills, and a great sense of humor, he makes each workout session interesting and enjoyable! I came to Ronan 2 years ago with recurring neck pain and frustration in my workouts. Within a few months, my neck was fully functional and pain-free, while my overall health greatly improved. We start each session with a check-in as to how my body responded to the previous workout and we go from there. Thanks to Ronan, I have remained injury-free and am finally achieving my fitness goals!”

    Yvonne T.

  • “I've been training with Gabe since 2018 and he is a rockstar. He goes above and beyond to help fine-tune programs that work great for me. We've not only hit major strength and cardio milestones in the past, but he's helped me rehabilitate and recover from a cycling accident too! He's a great trainer who cares a lot about his clients and their progress!”

    Michael N.

  • “I have been training with John for about 3 months now and the experience has been amazing. Ronan has been super professional and responsive in setting up the training sessions and John has been equally as responsive and professional. John has helped me put on more muscle and has taught me how to sustain growth outside of our training sessions. Words cannot express about how much I've enjoyed my time at Leap.”

    Ethan

  • “Ronan’s expertise is simply top-notch across the board. In two months I’m down 17 pounds, feeling stronger and better in every way. I cannot recommend him highly enough. He knows just how far to push and keep you advancing towards goals while also being mindful of the complexities of the human body. A master of his craft. Truly.”

    Jeff

  • “Leap Fitness is awesome! I started training with Ronan and Gabriel about three months ago. I came to Leap as I am a busy working mom of two and wanted to gain strength and drop some lbs! It has been such an incredible experience working with the team at Leap. They are truly fitness experts! Not only are they easy to work with, but I have also seen real results. I used to be on the cardio circuit full time and it was time for a change. I can feel my body getting stronger and I’m having a great time. If you want to change up your routine and need a kick in the butt—I would highly recommend the Leap team!”

    Jana

  • “Leap is an amazing training and wellness studio. I’ve been going there for almost three months and the results are phenomenal. I feel healthier, stronger, and experience less pain. Ronan takes a wholesome approach and addresses not just physical fitness but also nutrition and mental well-being. I train with him once a week focusing on mobility and physical strength. The entire team is great at creating engaging and challenging programs that improve my fitness. They deliver the training in a one-in-one environment allowing for personalization and privacy. The studio is clean, large, and private. I love Leap and would highly recommend them to anyone.”

    Brenda

  • “I have struggled with snapping hip syndrome and various other hip issues for over 8 years, seeking help from multiple personal trainers with little to no improvement. However, my experience with Alvaro has been nothing short of life-changing."

    Dani P.

  • “I have been working with Ronan and Jazmin for a few months. I was having specific mobility and pain issues in my right hip and knee. Now, I’ve completely cleared up and I’m now on a weight loss program. They keep me accountable with my diet and exercise program. Most of all, I am feeling stronger and more energetic. Their knowledge and attention to detail are what sets them apart from my past experiences with trainers. So happy with my results.”

    Howard

  • "Ronan and Leap have been a game changer for me. I had gained a ton of weight and didn't know how to get out of my rut. I've been working with Ronan for 2 months now and I've lost 15 lbs and feel a million times better already. He and the team are kind and patient, but also push me just enough to go out of my comfort zone. Can't recommend enough!! I wanted to add to my post now that I've also had a chance to also train with Gabe at Leap! Gabe is awesome - he pushes me the right amount but also listens to me if something doesn't feel comfortable. He's thoughtful in planning my workouts and always makes them fun! I've now lost 25 lbs in 5 months with Ronan and Gabe! Leap has really helped me turn things around."
