What Clients Say About Working With Andrea

Most of what you’ll find about a dietitian online is a polished bio or a stock photo of a smoothie. Here’s what clients actually said, in their own words, lightly trimmed for length but otherwise unchanged.

Individual results vary. The experiences below reflect specific clients’ outcomes and aren’t a guarantee of similar results for every client.

HYROX & Hybrid Athletes

“Working with Andrea has been such a positive, life-changing experience. I’ve lost weight and inches, but more than that, I’ve gained confidence, knowledge, and a healthier relationship with food and exercise. Nothing ever felt like a generic plan, everything was personalized to my goals and my life. She taught me how to fuel my life rather than simply follow a diet.”
— Jackie B.

“Before working with Andrea, I trained hard but didn’t always have the energy or recovery to match it. She built a practical nutrition strategy around my training schedule and a race-week fueling and hydration plan that was easy to follow. I felt stronger in the later stations, maintained my energy through the race, and recovered much faster afterward. She understands the demands of HYROX and knows how to translate sports nutrition into a plan that actually delivers.”
— Michael R.

“I used to train consistently but often felt flat during sessions and struggled to recover between workouts. Andrea built a structured nutrition plan around my training week and a clear race-week carb-loading and hydration approach that removed the guesswork. On race day I felt steady through the runs, stronger in the final stations, and my recovery afterward was noticeably faster.”
— James T.

Runners & Endurance Athletes

“Working with Andrea has completely changed the way I think about fueling my body. Especially with running, I feel stronger, more energized, and way more confident about what my body actually needs.”
— Kerry

“I’m a runner and needed to lose weight without sacrificing my training. Andrea worked with the lifestyle I actually have, not a generic plan, and taught me what I needed to know to maintain it on my own going forward. I’d be lost without her.”
— Jennifer O., Chicago, IL

Weight Loss & Body Composition

“I wanted to lose fat while also gaining lean muscle mass, which is tricky and can be frustrating (I know, because I tried it without help first and got almost nowhere). Andrea had me on the right track in no time. Her suggestions were realistic and actually fit my lifestyle. I’ve dropped from 35% body fat to 27%, and the fat keeps coming off while my performance in the gym keeps improving.”
— Mary H., El Centro, CA

“Andrea is an amazing sports nutritionist. I’ve been active my whole life but was never happy with my eating habits during training. She helped me see food as fuel and is extremely knowledgeable, not just about what works for me, but why it works. In three months I dropped over 2% body fat and, more importantly, learned a lot along the way.”
— Karen O., Encinitas, CA

“If you want to change your body and change how you think about health and nutrition, work with Andrea. I’ve been with her since February 2012. I’ve lost 10 pounds and gone from 19% to 14% body fat, but the bigger wins are better workouts, better mood, better sleep, and better skin. She’s accessible, responds quickly, and genuinely cares about her clients.”
— Kayla B., San Diego, CA

Metabolic & Clinical Health

The following reflect specific individual clinical outcomes and should not be read as typical or guaranteed results. Always work with your physician alongside any nutrition coaching involving a diagnosed condition.

“I was diagnosed as a type 2 diabetic and reached out to Andrea for help. My A1C was at 15 at diagnosis, positive for diabetes. A year later, largely because of her guidance, it was down to 6. She helped me build a nutrition and exercise routine that’s become my medication. I’ve also dropped 30 pounds, mostly around my waist, and have more energy than I’ve had in years.”
— Joe B., San Diego, CA

“I reached out to Andrea about elevated cholesterol because I didn’t want to start the statin medication my doctor had prescribed. She gave me the information and the plan to bring it down without medication, and my recent bloodwork shows a significant improvement. My doctor is on board with holding off on medication for now. I don’t think I’d have gotten here without her.”
— Heather L., Fair Lawn, NJ

Athletic Performance

“I’m a former college tennis player who never focused much on my diet. In my early 30s, I needed a real wake-up call, and working with Andrea was exactly that. She’s positive, encouraging, and genuinely knowledgeable about nutrition, training, and supplements.”
— Stacy M., San Diego, CA

“Andrea makes nutrition feel simple and realistic. No crazy rules, just practical advice that actually works with real life, and I’ve noticed a big difference in my energy and performance.”
— Chris

General Health & Lifestyle

“I travel constantly for work, which makes consistency hard. Andrea understood that and built a plan around my actual schedule instead of asking me to force my life around a diet. I already know a fair amount about nutrition, and I’m still learning from her regularly.”
— Amy J., San Diego, CA

“Andrea is not just a dietitian, she takes a genuinely whole-person approach to health. She goes well beyond a standard meal plan and tailors everything to your specific situation. In four months of working with her, I’ve built lean muscle, gotten faster, and noticeably increased my energy through diet and training changes together.”
— David J., San Diego, CA

“I originally hired Andrea for professional guidance with nutrition, but she turned out to be so much more. She approaches nutrition from a fully-rounded health perspective, taking into account my exercise regimen, work schedule, and lifestyle, and making sure everything worked together. She even customized my nutrition around high-altitude ski trips, which helped a lot. I’ve gotten noticeable results with gut health, energy levels, weight loss, and leaner muscle mass. She’s a wealth of knowledge and really understands how to guide a realistic approach to staying fit while living a busy life. Her energy is contagious, I feel uplifted just from our sessions. Hire her, you’ll be happy you did.”
— Kevin Grant

Youth & Collegiate Athletes

“I gained lean muscle while keeping my performance sharp, and Andrea’s plan flexed with me the whole way. In the offseason, she built a nutrition plan around gaining weight the right way, real muscle, not just pounds, mapped to the demands of playing O-line at San Diego State. She tracked my body composition, strength, and energy and adjusted things as I changed. Once the season started, she shifted my plan from gaining weight to holding my playing weight, staying strong and fueled through practices, lifts, and games. She even stayed in touch with my coaches to make sure everything lined up with what the program needed. She held me accountable and taught me how to actually fuel like an athlete, not just eat more.”
— Kyle B.

“I went to see Andrea to talk about my half-marathon training and how to lose a little weight before my wedding. She helped me get on track with my eating, training habits, and workout regimen. She was knowledgeable, friendly, and always available, by email or at the gym, even when I was having a rough time elsewhere. If it hadn’t been for her, I probably would have quit. If you need help with food or training, do what she says and you’ll see results.”
— Gabbie N., San Diego, CA

“A few months ago I decided I needed to change the way I eat to get back into shape, so I asked Andrea to help me understand food and what I actually need day to day. She didn’t hand me some crazy diet, she introduced foods I hadn’t been eating and showed me how to cook at home instead of eating out. It’s not always easier, but it’s a lot healthier, and I feel better knowing what’s in my food. I’m sticking with it even now that I’ve hit my goal.”
— Scott S., San Diego, CA

“Andrea is incredible, passionate about what she does, and it shows. I went to her for help losing my baby weight. Not only have I lost the weight, I feel great. She truly helps you understand your own nutrition so you can live a healthier, more active life while meeting your actual needs.”
— McKenzie A., Carlsbad, CA

“Andrea is amazing. I initially came in for an assessment about 8 months ago just to see what it was all about. I’ve been seeing her monthly since, and I’m down 15 pounds, but more importantly down in body fat, with better numbers across cholesterol and triglycerides too. I’ve learned to exercise more efficiently and changed my lifestyle for good. She’s also realistic, she knows I’m going to go out and have a cocktail sometimes, and we work that into the plan so I still see results.”
— Nicole L., La Mesa, CA

“I’ve worked with Andrea since 2012, through some real life milestones including preparing for my wedding. She got me where I wanted to be on my big day, and I was actually learning about nutrition the whole time, not just following a plan. Beyond the workout ideas, learning how to eat to support healthy weight loss and maintenance has helped me stay consistent as a wise eater long after the wedding.”
— Mari M., San Diego, CA

“I was the heaviest I’d ever been, with no energy and low motivation, when I started with Andrea. Her positivity helped me break out of that routine, and she built a lifestyle plan that was realistic enough to actually stick to. My triglycerides went from 450 to 200, my blood pressure came down, and I’m no longer pre-diabetic. The information itself is out there for free if you look for it, but something about how Andrea coaches makes actually following through possible.”
— Marcus A., Chino Hills, CA

“If you need help with eating habits and meal plans, Andrea is who you want. She’ll write you a plan tailored specifically to your goals, and it works. I saw her with the goal of leaning out, and after a couple of months the results were obvious. When I slacked off, I lost progress, so I came back to get on track, and I’m already seeing it again after a week and a half.”
— Tyler H., Alpine, CA

“I’ve been working with Andrea for several months and the results, physical and mental, have been hard to put into words. She takes a holistic approach to transforming eating habits and motivation, not just handing you a diet. The food journaling through her app sounds tedious but it’s genuinely part of what makes it work. I have more energy and more accountability with my habits than I’ve ever had, and she’s just an incredible person to work with on top of it.”
— Caroline S., San Diego, CA

“H2O Nutrition is the best. Andrea is very knowledgeable and helped me reach my goals in an educational, realistic way. I’ve never felt better or stronger.”
— Kipp G., Encinitas, CA

“My first meeting with Andrea was wonderful. Her energy got me motivated to work on my health and nutrition again. She’s knowledgeable and genuinely cares about her clients’ goals, and she didn’t hand me food restrictions or an unrealistic plan, just help balancing out my diet. I’m excited to see where this goes.”
— Sahar B., San Diego, CA

“Andrea isn’t just a wonderful person with great energy, she knows her stuff. She’s clearly passionate about what she does and practices what she preaches, which matters. I’d recommend her without hesitation to anyone looking for nutritional guidance.”
— Andrew C., San Diego, CA

“I was referred to Andrea by a friend who’d had great results with her. She set up a nutrition and workout plan that fit my needs and helped me feel good about myself, and recommended supplements that supported my goals too. I’d been confused by conflicting advice online for a long time, so it was genuinely useful to get answers from a professional and a plan built specifically for me. I lost 12 pounds and 4% body fat working toward my wedding, but the bigger win was actually understanding what my body needs.”
— Christina B., San Diego, CA

“I was excited to meet Andrea because she builds a program around your actual body type. I started with training sessions and had fun getting pushed. I’d also been dealing with digestion issues, and her recommendations for adjusting my eating did more for that than any doctor had. Her enthusiasm and positivity have been the best motivation, I can’t thank her enough.”
— Sandy I., San Diego, CA
