  • John Rickard

    Practice Manager

    John Rickard is the Business Manager for the Practice (as well as providing computer support, web & graphics design, and the one who has to do all the heavy lifting). Little did he realize when first he first met Dr. Rickard (10 years ago...then just Valeria) that he would eventually marry her and become Business Manager for NOAH. Funny how things work out...

    John was born and raised in nearby Thurmont, Maryland, by wonderful parents who instilled him with strong values, honor and common sense. John's dad Glenn owned his own business as well as possessed the skills required to build their house (along with HIS father). Just working along side him allowed John to develop his work ethic as well as learning all his life-practical handyman-type skills. Throughout high school and college, John "pushed the envelope" in both the Math and Computer Sciences departments (that time not being very extensive) and found his own way to leverage those areas towards a Bachelor's Degree from Mt St Mary's College.

    At age 14, John attended his first martial arts class, thus beginning an introspective journey which continues today. For the next 23 years, he has studied with a non-profit, traditional Martial Arts school - In Ji Yong Martial Arts - in Frederick Maryland. He has earned the rank of 3rd degree black belt and today teaches both children and adults in the same traditional fashion that he learned.

    In addition to the many "menial" jobs held throughout school, and his martial arts teaching, John has worked as a computer programmer and software designer in both the Public and Private sectors, landing as Senior Software Designer for UUNET -> WorldCom -> MCI -> Verizon).

    At home in Haymarket, with his wife (Dr. Rickard) he tends the herd and tries to keep the house from being taken apart by the numerous dogs & cats they have as well.. so add kennel assistant and dog groomer to the list of jobs. In his "spare time" John enjoys traveling and scuba diving.
