My fitness journey began over 23 years ago in a small training studio in Carmel Valley. While studying Biochemistry at UCSD, I started at the front desk but quickly transitioned to working with clients and teaching group fitness classes. I discovered a passion for helping people that led me to a fulfilling career in the fitness industry.
I’m certified through the National Strength and Conditioning Association (NSCA) as a Strength and Conditioning Specialist. I’ve also obtained my Special Populations Certification, allowing me to work with:
I’m also completing my second level of Egoscue training, which focuses on postural assessment and corrective exercise.

Mark's profile lists active aging as the main focus areas.
Skills and services the profile names: Corrective Exercise, Postural Assessment, Group Fitness, Strength Training, Functional Training, Cardiovascular Endurance, Flexibility & Mobility, Online Training, Private Training, Injury Prevention, and Semi-Private Training.
On format, the profile mentions one-on-one private sessions, semi-private sessions, group training, and online coaching. Confirm what is available and how it is priced at your introduction.
Active aging training keeps strength, balance, mobility and independence high as the years go on. It uses progressive resistance work, balance practice and joint-friendly conditioning, because muscle and movement skill respond to training at every age.
Your coach asks about medical history, medications and limitations, and works within any guidance from your physician.
Sit-to-stand, carrying, pushing, pulling and getting up from the floor are trained directly, because they decide how independent you stay.
Short, specific work on balance, hips, ankles and spine keeps movement confident and reduces fall risk over time.
Volume and intensity progress gradually, with more rest where it helps, so you finish feeling better rather than depleted.
Every plan is built around the individual, so your coach will adjust this. As a general shape, the first four weeks of active aging coaching tend to run like this.
Health history, current activity and a gentle movement screen. Sessions begin with simple strength and balance work.
Sit-to-stand, carries and light resistance work are repeated until they feel easy.
Loads and balance difficulty rise slowly, with extra rest where needed.
You notice what has become easier, such as stairs or getting up from the floor, and set the next goal.
