Josh did a great job assembling an 8x6 metal shed for me. I was coordinating everything from out of town, and he made the whole process easy. Communication was great from the beginning, he showed up right on time, kept me updated throughout the job, and sent pictures when everything was finished. The shed took longer than expected to put together, but he still honored the price we agreed on and made sure the job was completed properly. Everything came out great. I would definitely recommend him and would use him again.

I highly recommend Coach Talita Alencar! She has been providing self-defense classes for my 10-year-old daughter and her friend, and our experience with her has been excellent from the very beginning.
Before we even booked the classes, Talita’s communication was outstanding. She was responsive, patient, and took the time to answer every question we had, which made us feel very comfortable moving forward.
What I appreciate most is her teaching style. She is tough and pushes the girls to challenge themselves, but at the same time, she is caring, encouraging, and clearly invested in their progress. She has taken the time to understand each girl individually, recognizing their different strengths and weaknesses and adjusting her instruction to help them improve and overcome the areas where they struggle.
It’s been great watching their confidence and skills develop under her instruction. You can tell Talita genuinely cares about teaching them not only how to defend themselves, but also how to become more confident in their abilities.
We couldn’t be happier with the experience and would absolutely recommend Coach Talita to any parent looking for a knowledgeable, dedicated, and caring self-defense instructor for their child.

I started taking my kids to JJ Science Core for Jiu-Jitsu and self defense a few months ago, and the results have been incredible. Not only have I seen improvements in their fitness, but I’ve also noticed a positive change in their discipline, confidence, and overall attitude.
After seeing their progress, I decided to start taking classes myself. I’ve been challenged in all the right ways and have really enjoyed the experience. I’m especially impressed with Coach Talita’s ability to adapt to each student’s skill level while still providing the right amount of challenge. She has a way of making complex techniques easy to understand and creating an environment where learning feels both engaging and rewarding.
I highly recommend JJ Science Core to anyone looking to begin or elevate their fitness and martial arts journey. Whether you’re a complete beginner or have years of experience, you’ll find excellent instruction, a welcoming atmosphere, and an opportunity to grow.

She is truly an exceptional martial arts instructor. Since I arrived in the United States, she has played a huge role in helping me evolve my jiu-jitsu and overcome new challenges. She has worked extensively on my mindset, which has made a tremendous difference both on and off the mats. Her passion, dedication, and commitment to teaching are evident in every session. She is a 6-time Jiu-Jitsu World Champion and a professional MMA athlete ranked in the UFC’s Top 15, bringing an incredible level of knowledge, experience, and professionalism to her coaching. Her teaching methodology is outstanding, making complex techniques easy to understand while helping each student reach their full potential. I highly recommend her to anyone looking to learn self-defense, improve their martial arts skills, or train with one of the best professionals in the MMA and jiu-jitsu world.

Talita has been coaching our three kids (ages 4, 6, and 8) in jiu jitsu and fitness, and what makes her stand out is how much attention she pays to each kid, not just the physical skills.
Each of our kids has had a moment where they were nervous or hesitant about something new, and Talita noticed exactly what was going on and helped them work through it in a way that actually stuck. She has a great way of turning a hard moment into a real lesson, reminding the kids that their mindset shapes what their body can do.
Our kids have told us they feel proud of what they accomplish with Coach Talita because she pushes them outside their comfort zone. One of them even said Talita is one of the only teachers they want going forward, which is a pretty strong endorsement from an 8 year old.
She's patient, encouraging, and clearly loves working with kids. We highly recommend her.
