Get into your best shape for life!


Hello. My name is Kathleen and I would love to help you reach all your fitness goals!

My Background

I have had my own personal training business for 25 years, which began with 4 years of managing a back and neck rehabilitation center for an orthopedist. I graduated from the University of San Diego, and also completed a spinal rehabilitation program at the University of Florida. I am certified as a personal trainer through the American Council of Exercise (ACE), TRX, and Johnny G.

My Philosophy 

I have a strong passion for helping my clients to achieve their best health and life, and to feel and look their best. I have trained many of my clients for more than 18 years, and truly care for each of them. I do my best to make a great positive difference in each of their lives, including their physical health, confidence level, and attitude.

What to Expect

I strive to customize each individual's program according to their unique needs, goals, and limitations. I incorporate a variety of different types of training techniques to make each session challenging, interesting, safe, and fun.  I consistently provide the motivation, knowledge, and support necessary to keep them on track.  I work with all fitness levels and all ages, from youth to older adult. I would love the opportunity to work with you, and will do my very best to make your training experience as enjoyable and rewarding as I possibly can.

Diverse Training

Workouts may include strength, flexibility, cardiovascular, conditioning, agility, rehabilitative, corrective, and functional exercises (focuses on movements necessary in everyday life, and proper body mechanics), TRX (suspension and rip training), tabata, HIIT (high intensity interval / bust training), plyometric, boot camp, boxing, and sports specific training, yoga, and mat pilates, in addition to traditional training, depending on the individual's needs. I offer nutrition, weight loss, weight management, health coaching, postural alignment, neck and back stabilization and conditioning, and injury prevention.


I am available to train at private homes, offices, beaches, parks, and several private health clubs, from San Clemente to Monarch Beach and San Juan Capistrano. You are welcome to contact me any time. I would be excited to hear from you!  I am happy to answer any further questions you may have.
