Meet Jill, our newest trainer who brings a naturalistic, grounded perspective to The Butterfly Effect Studio. 

Jill is working towards a Bachelor of Science in Wildlife Ecology and a Bachelor of Arts in Anthropology at the University of Delaware, and comes from a family of yoga instructors and outdoor enthusiasts. 

When she's not in school or the studio, Jill is focused on the fine arts, animals, and adventures in the great outdoors. She's often drawing, writing, hanging out with her pets, fishing, or out exploring on hiking paths or 4x4 trails. Through these pursuits she gained a drive towards understanding and gaining a healthy body and mind- you can't go on many adventures without those!  

Her passions for nature and culture make Jill a valuable asset to the Studio, where she encourages clients to pursue their own balance in life and explore all that they can. She looks forward to meeting you and helping you on the path to life's adventures. 

Destini is the Spa Services Manager at BEST and a proud recent graduate of Delaware State University, where she earned her Bachelor’s degree in Public Health. She’s passionate about personal growth, wellness, and building a strong sense of community.

Outside of work, Destini loves spending quality time with her family, staying active with workouts, shopping, and enjoying outdoor adventures with her dog, Milo. She’s known for her positive energy and dedication to helping others feel their best—always aiming to uplift and inspire everyone around her.

Alexandra “Alex” DiBiaso is a 26-year-old NASM-certified health and fitness coach who brings compassion, structure, and consistency to every client. Her journey began at 17, when she weighed 200 lbs and hit a turning point—she joined a gym, changed her nutrition, and lost 50 lbs in 5 months. Two years later, she discovered weightlifting, and it became both her passion and her purpose: helping others feel strong, capable, and proud of the life they’re building. Alex supports clients through personalized strength, HIIT, and functional training, with a coaching style that’s encouraging, detail-focused, and built around sustainable habits. She also provides macro-based nutrition guidance and accountability to help clients stay consistent outside the gym. In addition to one-on-one and group training experience, Alex brings hands-on skill in manual assisted stretching to improve mobility, recovery, and overall movement quality. She’s committed to helping every client make progress they can feel—and keep.
