Penny Michaels


Swim Clinic Instructor

Coach Penny believes that swimming is a life-long sport! At a young age in Coral Gables, Florida, Penny got her start in swimming at the Venetian Pool. First she took Red Cross swim lessons, and then taught swim lessons through Venetian Aquatic Club. At that time in her life, swimming was more of a social event than a competition! Penny's coaching experiences include 3 years as a USA coach, ASCA level 1, and 3 years as a High School Varsity coach. Penny is also a certified NFHS, COSA, and USA swimming official. Penny divides the rest of her time away from the pool between her 4 daughters and is employed full-time as a School Nurse.

Holly Bradley



Coach Holly grew up swimming with a YMCA swim team in Massachusetts and continued to swim in high school and in college (Clark University, NCAA division 3).  The pool has always been her home away from home; some days spent jumping from practice to teaching swim lessons and then lifeguarding.  She continued to keep swimming in her life after college by coaching the same youth and high school teams she grew up with.  It is an amazing experience to share and teach others about this sport that has been such an impact on her life.

 When Coach Holly moved to Southern Maryland with her husband, she knew the pool was her first stop.
