Maria St. John

Maria is a Colorado native, born and raised in Littleton. She moved on to California after high school to attend the University of San Diego. Post-grad, she spent a summer working for the San Diego Padres on “Pad Squad”, aka she was a professional t-shirt thrower during baseball
games. She then followed her love of warm-weather and the ocean to Maui, Hawaii where she spent 5 years as a Wedding and Event Planner.

Family-ties brought her back to Colorado, and she is enjoying being back in her hometown. Maria was a multi-sport athlete growing up, and continued her love of fitness and exercise through her adulthood. She was introduced to Lagree in Maui from a dear friend, and was immediately hooked. The workout was killer, and the community was so supportive and
fun. Her other loves include her puppy, happy hour, and spending time with good-vibing people.


Lindsey has been teaching Lagree fitness since 2012 and has had the pleasure of being trained by Sebastian Lagree himself on more than one occasion. "You never forget a class taught by Sebastian!! It's a pretty intense experience "

Her appreciation for physical fitness can be traced back to her days competing in gymnastics, volleyball, and performing with a hip-hop dance crew. All of these experiences have made her the trainer she is today! 

"As an instructor, I care most about creating a fun and energetic atmosphere where people can get a killer workout and leave with new friends".

Katrina Prutch

Katrina has been active in sports and anything to do with outdoors since her youth. She has recently started SUPing in her journey to always have fun and enjoy the outdoors. She has been with the Southglenn team since opening their doors in 2013. Katrina was hooked from her 1st class and was amazed at how awesome and challenging this workout is. Since beginning with us she has had 2 beautiful baby girls and feels with her back ground as a Physical Therapist Assistant she can help you achieve your fitness goals.


 Hi my name is Amanda Parrott! I’m a fitness fanatic, former collegiate volleyball and soccer player, and professional Uber driver for my children.

I have 2 kiddos 7 & 10 that keep me on my toes! I love everything active and outdoors.

My passion is exercise and the impact it has on mental and physical health.


Alyssa is originally from Rochester, New York and moved to Denver in 2017. She started dancing at a young age and continued dancing throughout college, even minoring in dance at Ithaca College where she graduated in 2010. Fitness has always been an extremely important part of Alyssa's life, and especially fitness classes. It wasn't until she moved to Denver where she discovered Lagree, and like everybody else became addicted to this challenging, effective, and FUN workout. In 2019, Alyssa was taking at least 4-5 classes a week, and it became clear that she needed to get her Lagree certification. She has the best time creating playlists that will make this extremely tough workout manageable and the most enjoyable for everybody! When she isn't at Pilates Evolution Southglenn, she is a 2nd grade teacher in Denver Public Schools. Alyssa is also a part of a couple of different dance companies around Denver. In her spare time she loves being outdoors whether that is hiking, skiing, paddle boarding, or camping in the summertime!

Brooke Farrell

Originally from Colorado, Brooke moved around from Kansas to Chicago to California until finally landing back home. Having battled autoimmune issues the majority of her life, Brooke turned towards movement to help herself heal and she completed her 200 hr RYT and RockIt Body Pilates certifications while living in LA.

She is a nerd for anatomy, has found a recent obsession with pre and post natal movement and prides herself in making class challenging yet accessible. 

When she’s not teaching you can find her doing anything that involves the outdoors, petting every puppy she passes and busting out the awkward t-rex on the dance floor.

Hi I’m Lexie! I grew up in Littleton Colorado and attended Concordia University Chicago, 

where I earned my Masters in Health & Exercise Science with a concentration in nutrition. I have always loved being active and have reaped the positive benefits from a very young age. My passion for fitness grew in college, where I found a strong community that I could rely on during difficult times in my life. I have dabbled in most types of training ranging from yoga to HIIT to weight training. My passion is rooted in finding sustainable ways for my clients to find joy and fulfillment in their fitness journeys. I believe that a strong foundation and a persistent mindset can take you well beyond what you thought possible! Aside from my role as an instructor at PE I am a full-time teacher and part-time health and wellness coach for Empower Health and Fitness.


Hi, I’m Kelly Crettol and I LOVE Lagree fitness! 

I took my first Lagree class over twelve years ago and I’ve been hooked ever since. As a client, Lagree changed the way my body feels and looks. The workout pushes me mentally and physically in ways I’ve never experienced before. It is a mix of physical strength, flexibility but most importantly mental fortitude and power. 

I’m a strong believer that movement helps heal the body and Lagree has been my salvation in easing the pain and grief I’ve experienced from a lifetime struggle with endometriosis. I’m an early riser, so a morning Lagree class is my version of a cup of coffee and the best thing I can do to set my day up for success – a good shake and sweat can easily take my mind off the pain and anguish of the disease. 

After being a client for such a long time, I finally decided to share my love of Lagree with others, and I became an instructor in July 2023. 

Come join me for an early morning class and get your body moving!


Hi I'm Sara! I grew up in Littleton and moved out of state for awhile before finding my way back home. I have a degree in Health and Exercise Science which really made me love movement and nutrition! I love spending time outside, traveling, and with my family. I’ll take a good book or a puzzle any day of the week.

Come see me Thursday and Sunday mornings!
