Kristy Gharabally
Personal Trainer
Specialty: Functional Strength & Body Composition

Fitness should fit seamlessly into your life—not overwhelm it. As a NASM-Certified Personal Trainer since 2021,  I help busy parents and professionals build resilient, functional strength that lasts.

My passion for specialized strength training began after having kids. Navigating pelvic floor and core recovery firsthand showed me the power of targeted corrective exercise. Coming from a demanding corporate background, I also know how difficult it is to prioritize fitness amidst a packed schedule. Making the switch to in-home workouts showed me that fitness doesn't have to compete with family life—with the right setup, feeling strong and healthy is always within reach. When I’m not training clients or squeezing in my own workouts, you’ll find me outdoors—hiking, paddleboarding, skiing, or walking our dog with my husband and two kids. I look forward to helping you build your strongest self!

Rheanna Rinauro
Personal Trainer
Specialty: Weight Loss & Sports Conditioning

I have been a ACSM certified Fitness Professional for 4 years. My passion for fitness began as a young athlete at the age of 5. I specialize in functional training, weight loss, strength training, sports conditioning/performance, kickboxing and TRX suspension training. I make sure each workout and overall programs are designed to meet the needs, interests, and goals of my clients. I graduated from California State University of Monterey Bay in May of 2014, earning a bachelor’s degree in Kinesiology (also known as sports medicine) receiving honor roll. While attending college, I was a competitive softball player and interned for various wellness organizations. I worked under a physical therapist for all types of clients, as well as children with disabilities. I spent my senior year as an athletic trainer for football teams and loved every minute of my internships. Throughout my experiences, I took my passion, knowledge, and love for the wellbeing of others and turned my career into personal training. Here at Tower Personal Training my goal is to help my clients feel excited about themselves and have a positive outlook on not only the way they look and feel, but their life as a whole. What is truly exciting to me is to see my clients change mentally and physically through fitness and health, surpassing what they didn’t think could be possible! I love what I do, and I LOVE that I can share my passion with others!  Fitness is what I LIVE for, it’s not just a lifestyle.

As a lifelong athlete, I have always been driven to understand the biomechanics of the human body.

I’ve spent over a decade honing my skills, obtaining various fitness certifications, and winning the North Carolina Golden Gloves and US Muay Thai Open. The rigorous dedication required for combat sports not only has sharpened my training techniques, but has also reaffirmed the importance of a well-balanced regimen focused on all aspects of the mind, body, and spirit.

Crystal Eck
Personal Trainer and Nutritionist
Specialty: Weight Loss, Nutrition and Improving Health, Youth Training and Women's Health

My name is Crystal Eck and I am a mother to three daughters. I have a strong passion for health, fitness and wellness which became clear to me especially when I was pregnant with my first child and realized just how much our bodies change during those stages of pregnancy. This is the time I became extremely passionate about yoga, strength training, healthy eating and weight loss.  

I started my education at the US Career Institute becoming a Personal Trainer and Nutritionist. My education then took me into a Stanford University program where I developed an even stronger knowledge of Nutrition from studying Nutrition Science. Getting hired from the NFL working at 49ersfit in Saratoga, I transformed into a highly qualified trainer. Working one on one as a trainer with clients, I instructed HITT classes and an Ab class weekly and fell in love with the world of fitness. My knowledge grew at this facility and I knew fitness really needed to be loved at a young age and with nutrition. I followed that intuition and became the Nutrition Director for Gymguyz of Silicon Valley. For 5 years I created, developed and ran that nutrition program where I really got to pursue my expertise in Nutrition with all ages.

Then when moving to Half Moon Bay, I pursued working with the youth and became a PE teacher for the Cabrillo Unified School District teaching TK-3rd Graders. 

Being a certified personal fitness trainer and nutritionist since 2012 has been a career I can say I am very proud of.

Continuing to help the youth, young adults and women learn movement through play, focus on biomechanics, balance, stretch and strength along with finding joy in a healthy lifestyle is a goal I bring to Tower Personal Training. Helping all to live a long healthy, functioning, sustainable lifestyle and forever grow stronger is a goal I strive for.

My Certifications: 
- Nutrition Science from Stanford
- Youth Fitness Training ASFA
- IDES Certified for Post Pregnancy 
- Certified Personal Trainer: DEAC, IDEA. AFAA, ASFA

My name is Coach Michelle and I have been a certified fitness professional since 2017.

I am very passionate about helping others achieve their body, mind and overall health goals with fitness and nutrition and creating workout programs that are customized to my clients needs and matching their goals will always be top priority. 

 At Tower Personal Training my goals are to create more genuine connections with clients and to help them believe and achieve any level of health and fitness that they desire.
