Julia Walderzak, Owner

Screen Shot 2013-04-21 at 9.18.35 PM Owner Julia Walderzak founded H2K Happy Healthy Kids Fitness 4 years ago outside of Boston. As a child, Julia struggled with her weight and hated competitive sports, so she taught herself how to get fit and maintain a healthy lifestyle in other, non-competitive, ways. Knowing there was huge population of children and families currently struggling with the same issues she had overcome, Julia developed the concept for H2K. H2K was created in hopes of helping these families, who have been under-serviced in the past, learn how to live happy, healthy lives. Since becoming a new mom, Julia has experienced first-hand the importance of consciously maintaining physical, mental, and emotional health for both care takers and children alike. It’s her personal and professional goal to provide a resource for kids and families of all kinds to learn tools to stay happy and healthy in mind, body, and spirit.

Julia currently has her 4th degree red belt in Taekwondo and also has certifications in Zumba, kids Zumba, kickboxing, Radiant Child Yoga levels 1-3, and Yoga for Children with ADHD, Autism, and those who are Differently-Abled.
