Elizabeth Maniago, Studio Owner

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, got certified as a barre instructor, 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, AFAA Certified Group Fitness Instructor, and comprehensively trained Power Pilates instructor. She is currently wrapping up a year-long Classical Pilates Master’s program, under the guidance of a second-generation teacher. A member of the Barre Fitness Alliance, she is a certified Barre Intensity Advanced Instructor. Elizabeth graduated from Loyola University 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.

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.

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.

Lara Custer
Barre

Lara has been in the fitness world since graduating from High Point University with a degree in sports medicine in 2005. She worked for many bigger box gyms as a personal trainer, spinning, and boot camp instructor.  In 2012, she discovered barre, loving the low impact (but big results!) workout so much that she trained as an instructor and eventually opened her own studio in Timonium. She later opened Barrevolution Kent Island.

Lara and her husband Johnny have three beautiful children, ages 7, 4, and 2.

Lara is excited to come back as an instructor and share her love for barre with the Core Collective family!

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.

 
 
 

Erica Fox
Pilates

Erica spent 15 years of her childhood in dance classes. This passion continued into adulthood, where she also developed a love of Pilates. Erica immediately saw how Pilates complemented and strengthened her dance technique. It also helped with her back pain by keeping her body in alignment. Erica became more focused on Pilates in 2019 when she began training on the apparatus. She was recently certified as a Pilates mat instructor by Power Pilates and is eager to bring her unique style to the studio.

Erica grew up in Bucks County, PA. She graduated from Clarion University with a teaching degree in secondary mathematics. Erica and her husband moved to Kent Island in 2007, and they have never looked back. These days, she is busy taking care of her two daughters, two dogs, and a cat. She enjoys boating and listening to all sorts of music.

 
 
 

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.
