Summer hours are in effect from last week of June to August 29th.
Mon-Fri 6am – 8pm (unless there is a 7:30 class), Saturday 8:30-12 (with cardio kickboxing @ 8:30 and 9:30am), Sunday closed.
We are always open for Private Lessons by appointment.

 PowerHouse Kickboxing and Fitness is an Urban Martial Arts and Fitness Center.

Our focus is private, personalized training for each and every client whether it is in weight training, cardio kickboxing, or cross training.
We offer personal training, private group sessions, small group classes, kids’ classes, and self-defense programs.

Our Personal Training sessions are fully customized to your needs and with your individual goals in mind.

    Right Technique and Safety are our top priorities, therefore, we cap our classes at 8-10 athletes per class.

      The Youth, Ages 7-8, Class takes place on the Tatami floor. Boxing gloves are not necessary for a first free trial class but needed if your child decides to continue.


        To create a positive, wellbeing-centered environment where we all gather to enjoy what we do. To learn, to grow, and to excel as individuals and as a team. To share our knowledge, to empower and support each other and our clients, changing and improving our community one person at a time.
