Robin Billé

Robin is the proud owner of MEGAfit.  After a career practicing and teaching law, Robin is happily retired and enjoying a second career in fitness.  She is passionate about yoga and earned both her 200 and 300 hour yoga certificates from Charm City Yoga (now Yogaworks), where she formerly taught.  Robin started her second career in fitness at barre. where she trained under Marni Gorman.  She still loves to take and teach the method.

Robin believes in healthy living and tries to lead by example.  She considers her mega workout to create the solid foundation for all the other physical activities she couldn't live without!

Marni Gorman

Marni is the Master Instructor at barre.  She trained with the founder of Pure Barre before there was a "Pure Barre".  She's taken that training and honed it to such a point that she is considered by many to be the best barre instructor in town. 

She earned her megaformer teaching certification in 2013 (with Robin and Nan).   Marni puts her own twist on each class by layering barre moves into the classic megaformer workout.  Suffice it to say that her class is as fun as it is challenging!

Toni Paterakis

Toni fell in love with the megaformer workout while she was living in the midwest where she became a certified instructor.  Thankfully for us, she moved back to her hometown and joined the MEGAfit team.


Toni is a Lagree purist in the best sense of the word.  She believes whole-heartedly in the method and you will leave her class feeling like each muscle has been worked to perfect fatigue! 

Nan Rehfield

Nan is part of the Baltimore-fitness elite.  Like Marni, she's a former Lululemon Ambassador, and she's made a name for herself by teaching energizing classes set to great music.

Nan's signature style is fast-paced, cardio intensive and fun.  She loves playing around with new moves, and her energy is infectious!

Najat Ziyadeh


The strongest client in the class was always Naj!  Robin was so impressed that she had to train and hire her.  Nevermind that she spends her non-coaching hours working in the science field using her PhD.  We wanted her!

Her classes are inspired by her own commitment to excellence.  Expect to be challenged in the best way!

Samantha Berizzi

First and foremost, Sam is a competitor.  She came to Baltimore to swim competitively for Loyola and decided to stick around post graduation. 


She brings her enthusiasm and competitive drive to every class.  You cannot help but be inspired by her youthful exuberance and love of our workout.  Quite frankly,
she's the kind of motivation you need to keep from turning off that 5am alarm.  What a way to start your day!

Rachel Rutherford

Rachel is as warm and kind as she is beautiful and fit.  

She is our newest coach, but you would never know it based upon her poise and confidence.  Her classes echo her personality!  They are challenging, but her approach is so personable that you forget how hard you are being challenged to work.

Her warm smile and demeanor are not to be missed!
