A Few Words About Marissa – Jacksonville, FL

Marissa GainakasHello! My name is Marissa Gianakas and I am a Certified Pediatric Sleep Consultant and blessed to be a part of the Sleep Wise team. My husband and I met in Jacksonville, Florida and we have two boys, Benjamin and Alexander. I have a Bachelor’s degree in family, youth, & community science as well as a Bachelor’s degree in nursing. After working as a nurse in the NICU for almost 4 years, I received my Master’s degree from the University of Florida and became a Pediatric Nurse Practitioner.

I have loved babies and children since I was little. I started babysitting at a young age and was a “mothers helper” for several families. My career path followed as I have only worked with pediatric patients during my years of working in the medical field and now as a Pediatric Sleep Consultant.

Marissa GianakasWhen our first son was born, I spent many hours reading and researching sleep in order to help him become a decent sleeper. However, our second son did not follow the “rules” and what I had read in the books was not working. I did not have the physical or mental energy to keep trying different methods while also keeping up with a busy toddler. When he was just a few months old, I began working with the Sleep Wise team and saw an improvement on the first night! I was so impressed with my results and was excited to be rested and refreshed again, I had forgotten what that felt like!

My passion for babies, children, and families led me to become a part of the Sleep Wise team so I could continue to do what I love. Sleep not only has a huge impact on a growing child, but also for the rest of the family. I would love the opportunity to work together to help your family sleep through the night again!
