RAELEEN JADE M. MARIANO
Raeleen Jade M. Mariano, better known as “Rae” is the newest member of our team and the youngest one too! But don't be fooled by her youth and pint size. She is a highly motivated/firm individual who thrives in a fast-paced environment. She is smart, organized, works hard, and shows up everyday ready to learn and take on new challenges. Rae's nickname is “Mighty Mouse”, a name given to her by an observant patient that witnessed her ability to manage the entire office when Grace was on leave. Rae is very family oriented. She is the youngest of four daughters and has many nieces and nephews. She has a certificate of Mastery in Early Childhood Education, worked in the hospitality industry and has experience with customer service as well. As a result, she is able to work comfortably with our pediatric patients, manamko and their families. Our clinic and patients are in good hands with Rae!
