Meet The Redefining Strength
Leadership Team
Cori
I’m Cori Lefkowith the founder of Redefining Strength. The reason I can get my clients great results is because I’ve been the idiot that has made every mistake and experimented…Even with ridiculous things. I’ve been stuck in that diet and deprive, binge, guilt, binge, try a new diet cycle.
I’ve ignored injuries and pushed through only to end up more injured. I’ve gained weight and lost weight. I’ve worked out hard and then slacked off because I’m so burnt out.
And because I’ve made all the mistakes, I now know what works. That’s why I can help you.
I realize that each person has unique needs and no two fitness journeys will look alike. I’m a fitness nerd and former Division I tennis player and the 2011 Massachusetts/Rhode Island State Best Overall Raw Lifter. I can’t wait to help you on your journey 😊
Ryan
Hey, I’m Ryan, and I’m Cori’s sidekick and #1 fan. I grew up in Southern California playing just about every sport imaginable. I’ve always had a passion for helping people. I attended Berklee College of Music in Boston, MA, where I met Cori while we were both in college in the same city.
Fun fact: Our first date was when I told her I was going to show up to her tennis match, and I took her out to sushi afterward. Now we live in Southern California and have two dogs named Kiwi and Sushi.
Before joining Cori at Redefining Strength, I was a jingle writer! You’ll find me behind the camera at Redefining Strength, supporting all of your amazing health and fitness journeys!
Jessica
My name is Jessica, and I am so honored to be a part of your journey to becoming your best self!
I will be the first to tell you that this journey isn’t an easy one, and I know that because I have taken it myself. But I don’t want you to be afraid, worried, or feel overwhelmed. You aren’t venturing out alone this time!
I grew up on a farm in rural Alberta, Canada, and moved to the United States for college. I met and married my college sweetheart and moved to our dream Colorado ski town.
I’m an adventure seeker and thrive when the adrenaline is pumping. I’m an expert skier, backcountry snowmobiler, single-track and downhill mountain biker, and scuba diver. I’m also a wife and mom of three, and I love living the empty-nest lifestyle!
Michelle
My name is Michelle Alley and I am a registered dietitian. I believe in keeping nutrition simple and sustainable. We should enjoy our eating, not suffer from it. I know that small wins day to day create momentum towards larger goals. My spark for nutrition came as a collegiate track athlete who learned quite literally that I could not outrun a bad diet.
Since then I have earned two degrees in nutrition (BS in Dietetics, BS in Health Sciences with a Nutrition Emphasis) I and have worked the last 9 years counseling others to reach their nutrition and fitness goals. I’m an avid hiker, and love the outdoors. I’m also a bit competitive and love finding new challenges to continue to push myself and see what I am capable of. My current fitness journey has me pursuing triathlons and trail runs.

Coaching Team
Brooke
I’m Brooke and I’m a Registered Dietitian! Fitness, athletics, and nutrition have always been apart of my life! I grew up playing every sport out there, but truly fell in love with soccer. I eventually went on to play Division 1 soccer but during that time realized my passion was more in nutrition and overall fitness, not just soccer. I graduated in nutrition and dietetics.
I married my high school sweetheart who was also a college athlete so you bet there’s always a competition going on in our house. I love lifting, running, hiking, cycling, cooking and taking walks with my husband and dog 🙂 I love coffee and warm weather! What I love most about nutrition is that there is always a place to start! No matter where you are in your journey, I will meet you there and will help you take little steps to get you to you overall goals! All foods fit, and I am here to help you learn how to eat for YOUR body, and feel YOUR best every single day!

Ashley
I believe that health and wellness are the foundation that the rest of our lives spring from. My personal coaching philosophy stems from a deep belief that health is the vehicle that can usher in total life transformation. As you come into alignment with who you are, what’s important to you, and who you want to be, those intentions will bleed into your daily actions/habits/and mindset. Fitness helped to take me from a college dropout prone to anxiety and addiction to confident, thriving, and living a life of purpose. As we dive into WHY YOU are on this journey and what it means to you, we will come to know what shifts we need to make. You are the expert on where you want to go – I’m here to give you a roadmap on how to get there.

Sara G
I became super passionate about helping others overcome their health and fitness struggles after I went through my own during and after pregnancy. It helped me realize that sometimes we need a coach to be able to help see what we can’t see and learn how to be effortlessly accountable to our goals. I have a BS in Exercise Science, Minor in Psychology, Personal Trainer and Brain Health Coach Certifications.

Julia
My passion for health started during my time as a collegiate athlete, where I realized the immense impact that both nutrition and fitness had on my quality of life. Through my own health challenges, I went on to become a registered dietitian and certified personal trainer.
Today, I help guide others on their health journeys to feel their best, while simultaneously finding sustainable results. My favorite quote reads, “Give a man a fish and you feed him for a day. Teach him how to fish, and you feed him for a lifetime.” — and my ultimate goal is to teach you the necessary tools so that you may apply them throughout the remainder of your life. I am a proponent for creating a healthier lifestyle overall, without the need for extreme dieting and restrictions. I believe in small daily changes that will add up overtime to create remarkable improvement. Most of all, I’m passionate about helping you become the best version of yourself!

Andrea
My career in fitness has spanned over 12 years. As a Fitness Coach, I have helped countless people lose weight, run marathons, clean up their nutrition and even helped them touch their toes. More importantly, I’ve helped people feel confident in their own skin! Health and fitness have always been a passions of mine. I enjoy taking on new challenges and experiences.
I played on an international roller derby team, competed in a figure competition, ran a marathon and also played college softball. I have been a vegetarian for over 15 years. This way of life has opened up my eyes and taste buds to unlimited flavors but has also taught me an important lesson about planning and coming up with different tactics to ensure the food I’m eating is supporting my health. I believe in viewing food as fuel and/or medicine for our bodies. Once you understand the impact healthy eating has on your health, the possibilities are endless and also tasty!

An interesting fact about me is that it is my goal to become the oldest person to complete a marathon. The current record is 92. The advantage of doing it is that everyone will wait for you to complete it no matter how long it takes.

I love coaching! From a young age, I knew I wanted to be a teacher. I’ve worked in education for 15 years.

Working with clients to help them become their strongest selves is one of my passions.

Hey, I’m Megan, a holistic nutritionist and integrative health practitioner. I dove into health and fitness at a young age with sports and a desire to learn how to keep my body fit. That love for health just kept evolving into personal training and nutrition coaching and spending my free time learning and exploring the world of health and wellness.
In my 30’s I got more into hiking, mountain biking and trail running and I try to challenge myself with a couple outdoor fitness endeavors every year. I love to see what I can do physically and mentally and watching others challenge themselves inspires the heck out of me! My passion for health has always guided me to help others to improve theirs as well and I hope to continue to do so for many years to come!

Divergent interests and personality traits is my MO. I love schedules and spontaneity, hanging out inside to read and heading outside to run, spending time with people and being alone.

I love being able to meet you where you are at, no matter where you are in your fitness or nutrition journey and being able to help you reach your goals. I live somewhere near a beach with my husband, 2 dogs and a cat. I love cycling, SUP, lifting heavy things, traveling (pre-pandemic), the beach, anything true crime, gardening and give me all of the animals please!

Lynne
Growing up, I was always active and loved cooking from scratch. I dabbled with a couple of sports, but I was 100% passionate about cheerleading. I spent 20 years as a military spouse and mother. We moved often, but my love of exercise and good nutrition followed me wherever we moved. Over the years, I have enjoyed a variety of activities: strength training, sprint triathlon, 5&10ks, obstacle races, rappelling, fly fishing, hunting, camping…as long as it doesn’t involve a ball, I’ll try it.
After my husband retired from the military, I decided to put my degree to use and become a personal trainer. I guess you could say, I’m still a cheerleader. I just cheer people on hitting their personal goals.

I love to help my clients build strong habits that last a lifetime! I love to help people find their journey towards their strongest selves. I enjoy running, lifting, yoga, and water sports. When it’s time to rest and recover, you’ll find me reading a good book 🙂

Sara N
My personal fitness journey began over 20 years ago and it carries on to this day. During this time, I realized that I had a passion for helping others navigate what living a fit and healthy life looked like. I enjoy helping people find what works for them and encouraging them through the ups and downs (because there will be ups and downs). The truth is that during many of my downs, early on, I would scratch my workouts, but now they are a must do.
I know that living a fit life is more than the way I look – it is about the way I feel. I have learned through the years that when I put myself first and take care of myself I can be a much better version for everyone else. Being a military wife and mom of three amazing kids I know it is not always easy to take control of fitness and nutrition, but it is oh so worth it!

Emily P
I have always had a passion for all things related to health, fitness, and nutrition. I have experimented with different diets, supplements, and every type and style of training I can find. From trail running to CrossFit, Pilates, yoga, rock climbing, mountain biking, snowboarding, and jiu-jitsu – I love finding out what I am capable of and how far I can push my body.
The most rewarding aspect for me is helping others discover their own limits and then surpassing them to become the best version of themselves. Although I focus on helping people change their relationship with nutrition and fitness, it goes beyond that. Witnessing people evolve and thrive in every aspect of their lives is what truly makes me love what I do.

Valerie
My passion for fitness/nutrition started when I struggled to lose weight after my 3rd son was born. I dove into educating myself, lost the weight and became a Certified Personal Trainer.

I want you to experience the same life-changing positive effects that fueling our body via nutrition and exercise has on our lives!

Erin
My journey into fitness and nutrition started with a personal mission to lose weight and adopt a healthier lifestyle. Along the way, I discovered a passion for helping others achieve their goals. Every client brings a unique ambition, whether it’s losing weight, gaining muscle, or simply feeling better. My job is to craft a plan that fits seamlessly into your life. I firmly believe that any fitness or nutrition regimen should enrich your life, not dominate it.
That’s my aim for every client. Let’s ditch the rollercoaster of starting and stopping ineffective routines. There’s a smarter way: work efficiently, not excessively. Let’s build habits that become second nature. Discover a workout style you genuinely enjoy and eagerly anticipate. Because life’s too short for workouts that feel like chores. Together, let’s make fitness fun and sustainable—where every step forward is a step toward a happier, healthier you!

Emily B
Hey Y’all, I’m Emily B- a passionate, well-rounded advocate for fitness and wellness. With a journey that’s led me through various avenues of the industry. From teaching skiing, managing and coaching at a martial arts gym to co-owning a thriving CrossFit box, my career has been a blend of hands-on coaching and business management. My deep dive into alternative medicine and nutrition started at a holistic clinic where it sparked a fascination with the body’s intricate workings and a commitment to helping others achieve their healthiest selves. As a single mother of two amazing kids, I’ve embraced the challenges of balancing family life with my calling for fitness. I’ve competed in a wide range of athletic competitions, including CrossFit competitions, triathlons, Tough Mudder, and more—there’s not much I haven’t tried!
Competing in bodybuilding is now my new obsession. I am always pushing my limits and working on achieving new personal milestones. Becoming a Certified Nutrition Coach through NASM allowed me to blend my expertise with my genuine purpose of empowering individuals on their wellness journeys. I’m excited to bring my wealth of experience to Redefining Strength, where I strive to inspire, guide, and support others in reaching whatever their fitness and nutrition goals maybe. It’s Go Time!

My Love for cooking and eating good food pulled me in the direction to explore nutrition coaching. I am driven to help as many as I can to reach their goals and feel good about themselves!

Nikki
Hello! My name is Nikki and I am a mama of 3 crazy beautiful humans. I was born and raised in California but since then spent 6 years in Oregon and recently took a leap of faith and moved to South Carolina. I grew up a competitive gymnast and my whole life changed when I was forced to quit the only thing I ever loved at 16 because of a back injury.
After that is when my love for fitness and helping others on their journey began. I love to dance, camp, hike, snowboard and really do anything that has to do with water. Sometimes I wonder why I wasn’t created a mermaid because if there’s water – I’m in it!
Lauren
Passionately caffeinated, I’m always on a mission to sprinkle kindness and support wherever I go, all while fueled by my trusty sidekick coffee. When I’m not doing that, you can find me turning workouts into highly competitive events with my husband lol. And speaking of companions, there’s Jasper, the fluffy CEO of my heart.
I am thrilled to be a part of a team of like-hearted individuals who share a passion to empower others in achieving their dreams.
