Elizabeth Maniago, Studio Owner
Pilates, Barre, Personal Training
After recovering from spinal surgery, Elizabeth was eager to find a form of exercise that would strengthen her core, help her regain flexibility, and provide a low-impact but challenging full-body workout. She found all of this in barre and Pilates. Elizabeth dove in head-first and in 2018 took ownership of Barrevolution, a boutique barre studio in Chester, MD. Now as the leader of Core Collective, she continues to share the joy of movement with the Eastern Shore community.
Elizabeth is a NASM Certified Personal Trainer and Corrective Exercise Specialist, as well as a comprehensively trained, nationally certified Pilates teacher. She recently completed a Classical Pilates Master’s program, under the guidance of second-generation teacher Lesley Logan. A member of the Barre Fitness Alliance, she is a certified Barre Intensity Advanced Instructor. Elizabeth graduated from Loyola University in New Orleans with a degree in English Literature, and still loves curling up with a good book when she’s not at the studio. She currently lives in Grasonville with her husband, two children, bunny, and two golden retrievers.
Michelle Baudean, Studio Manager
As Studio Manager, Michelle combines her background in healthcare administration with her passion for building strength and supporting mental well-being through fitness. She first discovered Pilates at Core Collective in 2024 and quickly fell in love with both the practice and its supportive community. Inspired by that experience, she now brings her organizational expertise and people-first mindset to foster a welcoming environment for every member.
Outside the studio, Michelle enjoys reading, nature walks, and searching for seashells on the beach. She also enjoys dining at local restaurants and listening to live music. Michelle is a Maryland native and has lived on Kent Island with her husband, their three children, and two dogs since 2012.
Tina Reid, Lead Instructor
Barre
Tina took her first barre class in her home state of California in 2017 and never looked back. As someone who has struggled with knee issues for most of her life, she was thrilled to find a low impact routine that continues to challenge her at every class. After relocating to Kent Island in the summer of 2022, she immediately found her new home at Core Collective and trained to become an instructor. She looks forward to creating challenging, accessible — but most importantly fun — classes for all of her new friends.
When she isn't at the studio you can find her snowboarding (weather permitting) or riding her bike on the Kent Island Trail. She also loves to curl up with her two black cats and a good book.
Heidi Shiley
Barre
Heidi discovered Barre in 2017 when she was pregnant with her youngest. In 2019, Heidi took a Barre class at Core Collective and right away she noticed the community of strong women that gave her the feeling of empowerment after every class. After sweating through more than 500 Barre classes at Core Collective and becoming an instructor, Heidi is ready to share her love of Barre with others. She is also the face behind the screen across our social media platforms, serving amazing content and info on Instagram and Facebook.
Heidi is a mom to four beautiful children and a wife to one lucky guy. When she is not in the studio, Heidi can be found on the sidelines cheering on her children, running, boating, cleaning, reading, and having fun with family and friends.

She is an avid runner, participating in many local 5K, 10K, and half marathon races.

Abby Scaggs
Barre
Abby has always been passionate about performance, art, and movement. A born-and-raised local, she began her dance journey right next door at Step 1 Dance 2 Academy. In 2020, she moved to Philadelphia to attend the University of the Arts, where she earned her Bachelor of Fine Arts in Dance with a concentration in Business in 2024.
Now back home, Abby is thrilled to combine her love for dance and fitness by teaching Barre at Core Collective. After becoming a dedicated student herself, she knew she wanted to share that same energy and connection with others.
When Abby isn’t in a studio dancing or taking or teaching barre, you can find her with family in friends going for walks in the area, having coffee on the water, or traveling on the weekends.
Lauren Gray
Barre
Lauren found barre in 2024, and it quickly became her go-to low-impact workout, especially with her shoulders, which like to cause her trouble. The supportive community at the studio makes every class enjoyable, and barre’s combination of strength and flexibility has been a perfect fit for her body.
Outside of barre, Lauren enjoys riding bikes, spending time with her family and dog, and obsessing over her indoor plants and garden. She loves anything that involves being outdoors and taking in the fresh air. She’s excited to share the benefits of barre with others and help you build strength safely while having fun!
Jenn Neely
Pilates
Jenn discovered Pilates in 2005 after her first son was born. It changed her entire attitude toward exercise. In 2006 she became a certified Pilates instructor and taught mat and reformer classes in Annapolis for several years before returning full time to her 9-5 career. Although Jenn continued to practice Pilates over the years, it wasn’t until she found Core Collective that she was inspired to become re-certified and get back to teaching.
Outside of the studio, Jenn can be found at her kids’ sporting events, wandering the aisles in Trader Joes, working her 9-5 job providing CFO support to small government consulting firms, and headed to the beach any chance she can get. She lives on Kent Island with her husband, two sons, and adorable dog.
Keli Iannucci
Yoga
Keli’s love of group fitness led her to yoga in her twenties. Her personal practice has allowed her to feel good both mentally and physically, through the highs and lows of life. As a full time Pediatric Registered Nurse at Johns Hopkins, Keli took her first yoga teacher training in 2017 from Kidding Around Yoga designed for healthcare providers. In 2019, her passion and yearning to learn more led her to complete her 200 hour yoga teacher training at Ruah in Annapolis MD. Although Keli has taught many different styles of yoga classes, her true passion is to hold space for students to let go, unwind and recharge.
Keli and her husband are high school sweethearts who grew up in Connecticut. In addition to fitness classes, Keli enjoys her workouts outside, walking/hiking or bike riding. She loves spending time with her adult children, traveling, photography, boating, and spoiling her cat Oona.
