Krystal Overly
APRN/Owner of Sandy Key Med Spa
Krystal was born and raised in Alabama. Although a country girl at heart, she has lived in the Perdido area since 1999 and specifically Perdido Key since 2015. Krystal graduated from UAB in 1995 with a degree as a Fitness Specialist. When she couldn’t find a job in that field, Krystal immediately enrolled in nursing school, obtaining her ADN from Jefferson Davis Community College in 1997 and her BSN from the University of South Alabama in 1998. After working as a Registered Nurse for a few years, Krystal knew it was time to pursue her dream of becoming a Nurse Practitioner. In 2004, she graduated from the University of South Alabama with an MSN. Growing up, Krystal always dreamed of having a career in medicine, with a heart to heal people.
Most of Krystal’s career was spent in long-term care and skilled rehab, with some remote experience in urgent care and ER settings. In 2019, she felt it was time for something different. By 2020, she had begun obtaining certifications in aesthetics, starting with neurotoxins and dermal fillers. During one of those training sessions, Krystal learned about Bio-Identical Hormone Replacement Therapy, which immediately piqued her interest. She then pursued additional training, beginning at Buckeye Regenerative Medicine in Columbus, OH, and continuing through Empire Medical Training and Elite NP courses. With her background as a Fitness Specialist and a passion for health and fitness, adding weight loss services to her offerings seemed like a natural fit.
Krystal has faced struggles with weight, body image, self-esteem, and self-worth throughout her life due to various childhood and life experiences. Having undergone many of the procedures and services she now offers, her confidence and self-esteem have drastically improved. This personal journey has fueled Krystal’s deep passion for helping others who may seek the same level of confidence. She is dedicated to assisting others to not only look their best but also feel their best from the inside out. Krystal strives to connect on a deeper level with everyone who walks through the door, building trust and ensuring that each patient feels empowered when they leave her care.
Krystal is married to Chad Overly, a retired Navy Chief who has been in and out of the area since it was his first duty station in the early 90s. Since his retirement in 2015, The area has also become his forever home. Together, they have two daughters and two German Shepherds. If you sit in Krystal’s chair, you’ll likely hear all about Lilo and Ruger and probably see a few pictures too. While Krystal loves all animals, she has a special place in her heart for German Shepherds, having had four since first adopting Hank, who now lives with her daughter, in 2017. Krystal proudly supports local dog rescues, including the Joy Committee and Save Underdogs.
