LJJ has the 4 things you need for a great jiu-jitus school - a technical program, great…read moreinstructors, great students, and regular sparring. They have a great set of lesson plans with a focus on attack and defense from specific positions. For example, one week will focus on attacking and defending in the mount. Focusing on one position for the week allows you to see and practice the a solid package for that position. The positional sparring at the end of class allows you to immediately put what you've learned into practice to really solidify the concepts in your mind. The instructors do a great job of teaching the technical aspects of each move and answering any questions you have. The demonstrations of the techniques are slow, smooth, and detailed to make sure you know what's required to make the move work. You truly couldn't ask for a better group of students. Everyone is there to be the best they can be and help the students around them be the best they can be. Everyone strives to be technical and the bigger guys never get lazy and just smash the snot out of their smaller opponents or just muscle their way through moves. Some of the guys in the class are literal more than twice my size but they never crush me. I have great sparring matches Every. Single. Time. Once you get your first stripe, you can participate in open sparring after class. Sparring is essential to becoming a great practitioner of the art. Drills alone will never give you the timing and critical thinking skills you need to truly master the art.

Took my 7-year old son to camp here for two summers and LOVED it. I particularly loved Ms. Spencer,…read morethe main camp instructor, who is also a teacher during the school year. She makes sure she added educational aspects to the program, which is really important for me. A camp day is divided into various activities. Ms. Spencer also provides the parents a detailed list of how their day is broken down and a weekly itinerary. They play board games, exercise, do arts and crafts, and learn martial arts every day. Specific days of the week they go on field trips----movie theater, splash pad, museum, nature walks, etc. Oh and dont forget Friday show-n-tell. I had my child enolled at the YMCA before I found Greubels. I immediately cancelled my membership when I found out that my son was sitting on the basketball course at the YMCA for the entire day doing NOTHING despite the catalog-list of activities they "sold" me to get me to sign-up. Switching to Greubels was the best decision I made for both my son and I. Greubels has a small child to coach ratio and really works hard to ensure the program is balanced between mental and physical stimulation. They're always looking for new ideas and ways to provide a more creative environment for the children. I'm not really sure about some of the other reviews on here regarding the camp. It's not physically possible for an adult to be doing martial arts from 6:00 in the morning till 6 o'clock at night---let alone a child. I would encourage others to be cognizant that this is CAMP. Kids in camp are supposed to play board games and color and watch movies and just have fun. Some parents should have expectation management--- summer camp is not the place for your child to be the next fighting champion. So, if additional training is important for you, they should have considered enrolling their child in actual classes in addition to what camp offers as many other parents do--- which is even better because you get a discount off camp. My husband and I both work, so finding a camp that has a balanced program and one that offers early drop off and extended pick up hours (without extra charges) is really important. There are not a lot of options out there, which make Greubals really a great place to send my child. They know my name. They know my son's name and we are ALWAYS greeted when I drop my son off or pick him up. Ms. Spencer even remembered my son's bday 3 months after camp had ended and sent us a note to wish him a Happy Birthday. It was so touching! This year there were a lot of birthday parties and all the kids became friends and celebrated outside of camp too. When I pick up my son, he was always so excited to show me the new moves he learned in class and tell me about his day. Greubels has made my son incredibly happy and that is priceless for me. This had been a great experience for the both of us.
