I started coming in beginning of Feb 2026, with completely no idea about what to expect or what to do. It's part of the BJJ process. That being said, everyone at 805 was welcoming and encouraging so it made my first day an exciting experience. The instructors are friendly, patient and extremely knowledgeable. You'll have to put in the work but the instructors see that and will help you on anything you're stuck on. Almost five months in, I still feel the excitement that I felt on day one. Highly recommend! read more

Incredible place! Going on our second year with this Gym. We have three boys of different ages and they all love it here. Went to a competitor to see if it's a good fit and it was so loud that all three kids wanted to leave. So loud, I could barely hear the sweet young man manning the front desk in the middle of chaos. A few minutes after leaving, we got a call back from 805 to come see their place. The boys walk in, and in unison said "this place" while Coach cowboy and I were talking. He told them to take their shoes off and join the class. It was "home"... He is more than just a coach. He cares about all his students! When they fall out of line, he cares enough to help the parents get them back in line. He instills discipline, self esteem and values. All the coaches here are amazing! I'm so happy we joined Thank you 805 for making us a part of your family read more

A 2 year update! Still highly recommend 805 Combat! Family friendly and safe environment for everyone :) it's been a joy to continue this jiu jitsu journey! read more

My experience was amazing and I would like to share it to others as it was a fulfilling one. My life was going down spiral between work days and kids school. Drowning myself into mediocracy and unfulfilling dreams, seeing my life vanishing between my fingers. Broken dreams and Netflix nights were my tombstone. Until one day while picking up a pizza , I noticed what it looked to me a happy hour bar, since every person behind the foggy glass were having a good time while being punch in the neck. Loud laughing and music capture my soul dead ears again as my crusty fingers got embalmed of honey desires. Feelings of inadequacy and low self steem were high on those previous moments before I stepped in the soon to become my new reborn sanctuary and lifestyle. After cautiously observing the environment of men and chivalry between brotherhood which I once belong before on my youth, I wanted to feel alive again as the emotion were a verbatim reminder of what my ashes used to be. I embarked on this new journey with closed eyes and surrender any thoughts of selfishness as they usually hide behind self-pity and lame jokes. As a 45 yr young husband and father, I've been enjoying the taste of sweat and pain while I'm being choked out by a 22yr young buck. My bruised neck and night muscle spams that I been enjoying at night before going to bed, it tells a story or being alive again. The musky sweat of my peers crowns my new found freedom and revived my pale soul back to a colorful garden if vitality and masculinity. Now I stand tall while dropping my kids at school knowing that I can North choke the PE teacher any time my kids gets a F while I grind my chiseled, fully salt and pepper beard. Now I'm in control of my mind and body as I enjoy the camaraderie with other bald hairy bearded men like me that enjoy the struggle while give thanks for another day of Training. Salty floors and steamy sweat is my aphrodisiac as my wife tells me while she can't get enough of this new born baby ninja white belt stud she enjoys. Long live the King JC read more

The best. Our daughter is 3 years old and loves coming here. Chris and Josh are extremely encouraging and patient with the kids. My daughter tries her best to keep up with the older kids, everyone in class is supportive as well. She's definitely getting stronger. read more

Super clean facility. Super talented and excellent coaching. Really a great place to learn self-defense , BJJ and get a better version of yourself. Highly recommend. read more

Been doing a few private lessons with Josh and Jen. Great instructors and very patient. I come from a boxing background so this is new to me but I'm catching on fairly quicky due to their thorough and comprehensible demonstrations of the techniques. The facility is pretty big, allows for a lot of moving/rolling around and is well maintained. read more

My husband and children started attending this gym a few months ago and we couldn't be any happier. The attention to detail and connection the coaches have with the kids is amazing. I've seen my girls self confidence improve over these past few months. Excited to see their journey! read more

805 Combat Sports - Kids class with Cowboy! My kids love his classes!! - Brazilian Jiu-jitsu Near Me - Simi Valley, California

My daughters and I started here a couple months ago and we couldn't be any happier. The high level of experience from all the coaches is noticed in every session. read more

My son has been attending 805 for about 10 months now. He loves it. I've seen so much personal and physical growth in him. There was recently a change over in coaches. The current coaches have been really great and it was a nice change. They have fun with the students while providing great instruction. They always find a way to create real life situations for practicing their moves and they are so encouraging to them. They've also been great at fine tuning the students skills. Detailed and hands on instruction. I love good form so I've really appreciated the fine tuning. A quote from my son about 805, " the coaches are super nice and funny. I wish I could put 10 stars." read more

I love it! I want to do more Jiujitsu! Grant-age 7 My kids have been practicing here for over 9 years! Coach Cowboy has a fun and engaging style. The kids have learned a lot training here. read more

This is an amazing jit-jitsu training facility with skilled instructors and professionally run. Learning life lessons through self defense training and physical and mental well being. Highly recommended over any other establishment in Simi Valley. read more

recently enrolled my son, and he absolutely loves the training and the coaches, Josh and Chris. The coaches have so much patience, and make the class so fun. Abdiel looks forward to this after school activity every day. Thank you for teaching him self defense and confidence. read more

Great vibe! Not taking anything away from some of the other jiu-jitsu schools, but this one has a real workman-like blue-collar energy that I think lends itself to really solid training. Also, a great variety of belts, so you don't just end up going against all white belts all the time, like many places that focus on always cycling new people through. This place is inhabited by old die hards. If you are a tough fireman or something similar this is probably your tribe. read more

My son has been practicing here for a few months and he absolutely loves it! He wishes he could go every day and has already asked me if he could increase the number of days he can attend. He is very quickly learning incredible skills that the coaches teach at a pace the kids can follow. They are patient and keep the kids laughing and engaged. They have the kids demonstrate for one another and get involved with which moves they will learn and practice. The most critical thing I enjoy is the way the kids encourage each other and support one another. My son constantly gets pats on the back and "good job today" from older more experienced kids in the class, which is so great for his self-esteem. I also really appreciate the 1:1 attention the kids get from the coaches to ensure they are not only practicing the moves correctly but also in a way that they will protect and not hurt one another. The most important takeaway is that my son is smiling from ear to ear the entire class and can't wait to show off his moves to the rest of the family when he gets home. Learning skills, respect AND having fun. Can't ask for a better class! read more

Can't say enough good things! The coaches are so helpful and patient with the students and take the time to make sure everyone understands the moves. They keep the class structured but still fun! My 5 year old absolutely loves it and asks to come every chance he can! read more

Love this place! But more importantly my daughter LOVES it here. She's been here for about 18 months and she still gets excited to come and get some "work" in as she calls it. The coach's are really great and make it a fun environment for the kids to learn and progress in their Jiu Jitsu journeys. read more

Gym is great, been going here for a bit over a month and everybody is welcoming. Coaches work on such an individual level that it makes your technique perfect. read more

Love it!!! My Son was coming for 10 months before I decided to join. Great team of coaches. Great environment. And now they are offering even more. Anyone looking for fantastic physical and mental experience, this is the go to. Tons of support and fun. read more

My son has been attending here for a few weeks now and he loves it. He looks forward to going everyday after school. Just yesterday 5-10-23 after attending not more than three weeks, he was telling me how he feels he has learned so much already and I can see self-confidence starting to emerge out of him. read more

I've had the privilege of training at 805 for the past 3 years. We are truly blessed with the instructors we have, they love the art of jiu jitsu and can communicate it to all levels. read more

This program is amazing for kids, they do an exceptional job teaching my sons discipline & self-defense. I highly recommend!! 100%

I've been here for several jiu-jitsu seminars and open mats now and both the coaches and students are fantastic. Mark and Christian's technical knowledge is top notch and their students are always tough to roll against. They are a Jean-Jacques Machado affiliate so this isn't a surprise, but I feel its still worth mentioning. Plus they have tons of training gear you won't find at many other gyms, so whatever it is you're trying to practice they've got you covered! read more

Krav Maga is increasing in popularity in the United States each year. With so many choices offered by Krav Maga Association of America and International Krav Maga Federation, training in this intense Israeli self defense, combat, and fitness system is readily available. I was a student here for over 2 years and have loved every moment of the experience. The most impressive thing about this studio is the quality of instructors. I have talked to students from other establishments and they come here to train because of the high quality of instruction they get. Without a doubt, if you want your ass kicked then take a Krav Maga Level 1 course for a week. My first week blew me away as I was encouraged to kick, punch, knee, eye-gouge, and groin kick the living daylights out of my training partners. I was hooked ever since. Without a doubt the curriculum is also one of the most diverse. They have bag courses for fitness, fight class which include sparring, ground fighting, and my favorite, weapons class. Not to mention the special gun seminar, knife seminar, tactical pen seminar, and kid's curriculum. These classes seek to make the Krav Maga practitioner a well rounded fighter not just good at self-defense and combatives. It goes without saying that if you are in the area and want to learn something that is practical and maybe someday useful, then hook up with these folks. They kick your arse and smile while doing it, but when it's all done they are the friendliest people I know. read more

I've been training here for a while. Good instruction, particularly from the lead instructor (Jeremy Stafford). A great workout, and a lot of fun-all while you're learning useful technique. They also offer kids classes, and fitness classes that are tougher than anything you'll get at the gym. They offer a few classes for free, so feel free to drop in and try it without worrying about the cost. My only complaint is the one year lock-in to begin with (though you can pay up front for a discount). Still, most places around here require that. read more

I already left a review for 805 JJM Simi Valley. I'll re-iterate some facts. First, the professors there are highly skilled and qualified, both receiving their black belts from JJM! They both outwardly show care and compassion towards all their students and strive to not only make us better Jiu Jitsu practitioners, but better human beings. If you read some of the above commentors, specifically SUSAN R. she is bviously biased, completely wrong, and bordering on slander/liable. I have known Professor Mark for 10+ years and know him to be a hard working, caring, and upstanding individual. Mark completed is professional career and was given an honorable discharge, something he would have not got of her allegations were true. As for JOSHUA P. I was there the day he came in. He was welcomed and admonished regarding the level of training needed to participate in the days activities. JOSHUA became upset and stormed out of the gym. He was never treated poorly. Back to BJJ. I have trained at other academies and 805 is the best I have been to. Not only do we have amazing instructors but the bond/brotherhood that all the students have is second to none. If you're looking to get some amazing training and make life-long friends 805 JJM Simi Valley is the place to go! read more

I've known Mark for a little while now and he has been nothing but very professionally and kind to me. Mark is a hard worker and wants nothing but the best for others. My boyfriend knew Mark for several years and would also mention how professional, caring and outstanding of a person he is. Don't read miserable peoples negative reviews, they are the bullies for writing such horrible comments. If you want an amazing, professional experience, go to 805 Brazilian Jiu Jitsu! read more

After my long term experience in private training with Professor Mark Mirelis, I am compelled to write a review to highlight what a positive experience I and my children have had over the years. During this period of time, both my children and I have received what amounted to exposure to martial arts at the highest level. It was more than training. Professor Mark would always take time before and after training to sit down and discuss what the goals were for the day and always inquired of us how we were doing. He never hesitated to offer life experience advice which we took to heart. From the beginning, I wanted to know what I was getting myself and my children involved in. I discussed with him his background regarding martial arts as well as his previous life experiences. What I heard from him and what I discovered on my own was truly impressive. He is an honorably discharged Marine who had tours of duty all over the world. He is a three-time medal of valor recipient from the Los Angeles police department. He once saved a woman from a burning car after extracting her while the car was not only on fire, but had a live electrical pole fall next to it. Just this past New Year's eve, he was involved in a domestic violence shoot out involving a disturbed individual who came out shooting at every police officer arriving on scene. He successfully led a charge which, after was investigated the highest level of the Los Angeles police department, was noted to have used the finest tactics applicable to the deadly encounter. He has also volunteered his time to help implement more effective safety in defense of techniques for police officers in order to provide them with additional skills to protect themselves in the event of a violent encounter. Ironically, but not surprisingly, by being the first officer on a criminal scene, some of the people he has dealt with during arrest and others who knew that they could profit on his accomplishments have attempted to disparage his good name with sensational accusations and attempted to have media reports made about him to further their television ratings, all at the cost of his solid reputation. Fortunately, all of these unfounded accusations made by certain individuals and the press have been summarily dismissed when all the facts came out. Curiously, when people in the past have brought these issues up they have always conveniently failed to mention how these false accusations were dismissed at every level. To his credit, when I discussed these issues with him, he said that dealing with nefarious people was part of the job and it's something that he would never let defeat him. Regarding his martial arts background, he is a very accomplished wrestler having wrestled at numerous tournaments all over the United States, Europe and Asia. He is a third degree black belt at the at the Jean Jacques Machado Academy, which is considered the Harvard of Brazilian Jiu Jitsu. In addition to these accomplishments, he has authored numerous books on martial arts and self-defense. My children have been receiving instruction from Professor Mark for years. He has transformed them and both mind and body, while never letting them forget that the journey in bjj and in martial arts is not about your belt ranking but about your character. My children to this day never fail to look straight into your eyes and give you a firm handshake when they meet you. He has further taught them that all of the training in the world is no substitute for not continuing to be a respectful young adults and to always, always focus on their schooling. This is truly invaluable coming from somebody outside of our home. Furthermore, he has volunteered numerous times to coach them during their bjj tournaments. He always told them, "You will win matches but you will never lose a match as you will only learn from matches you don't win." I still use that saying to this day with my children. At the end of the day however, these accomplishments mean nothing unless you're able to be a person of character. He is a veteran who has honorably served his country. I have witnessed on numerous occasions other professors at various academies and other Los Angeles police department police officers comment on how he never failed to assist them or to lend an ear when they were facing a personal or work issue. Over the years, he has endeavored in several successful businesses and I have witnessed him being praised by his employees and has always had female employees assigned to high level positions. Ultimately, I cannot over emphasize how happy we are that he is the one that is leading me and my children down the martial arts journey. read more

The more comfortable you get being uncomfortable the more you grow. I still have a LONG way to go to get to where I want to be at Krav Maga "which will probably be a never ending process". I cannot express how thankful I am to have the trainers that I do who push me to be be a better version of myself every single time I step on to the mat. I challenge anyone reading this to try a class at Simi Krav Maga or 805 Brazilian Jiu Jitsu. You have NO IDEA the level of training this facility can offer to make you a better person in EVERY part of your life till you try it. read more

I have been training here since September 2011 and have found the classes to be very practical, a great workout, and quite entertaining. I first came across Krav Maga a few years ago, but I delayed in taking it up because I figured the classes would be filled with intense, military-minded men who lack any sense of humor. Glad to say that I was quite wrong. The entire staff is great. They know their stuff and help you reach your goals, but also make the classes fun. If you want a boot camp experience, they are happy to provide that. If you just want to build some self-defense confidence, they do that quite well too. The student base is very diverse, both in age and background/interests; Krav Maga is definitely not just for those dreaming of law enforcement careers. After spending many hours here over the past 6 months, I feel confident in recommending this place. My experience has been far better than I expected. read more

805's Friday night open mat class will kick your ass! Such a great Gi no Gi workout! Clean environment, helpful instruction and good attitudes. Glad my friend introduced me to this place! read more

So glad I found this place for my son. The coaches are patient, kind and genuinely care for the kids in there class. My boy came in with no experience at all and is learning so much thanks to the time and effort the coaches are putting into his training. They always take the time to brake down the movements and explain techniques, all while keeping class fun and exciting. After 3 months my son is still excited to go and seems to have found a new sport thanks to the coaches and wonderful kids he's training with at 805. read more

I've trained with Mark Mireles for over a decade. With black belts in both Judo and Jiu Jitsu and an extensive wrestling background, his knowledge of grappling is not possessed by many. I'd recommend this gym to anyone looking for top-notch martial arts training! read more

They do a generally good job with their training but you had better think real hard before you commit to their 1 year contract because they will not let you out of it and they will make sure to "continue with collections until all past due amounts are paid in full". read more

Good gym for kids BUT canceling membership is very difficult. Had to cancel credit card to keep them from charging me.

After a brief (and relatively ineffective) time with Karate, I enrolled my 11-year old daughter at Simi Valley Krav Maga. It was one of the best decisions I made as a parent. Krav Maga is a brilliant and practical fighting system designed to instill a high level of street-smart self-defense competency, efficiently and effectively. My daughter (now 18) is a Brown Belt and committed to going the distance to Black. Not only did she learn how to fight, but she dramatically improved her physical conditioning and self- confidence. Lead instructor, Jeremy Stafford is a SUPERB and committed teacher who will go out of his way for his students. Jeremy and his team of first-rate instructors run a great safe school filled with genuine esprit-de-corps. In fact, SVKM is more like a family. And as a father, there is nothing more thrilling than watching your child (man)handle multiple attackers during a stress drill. Thank you for everything, Jeremy. I worry about many things, but my daughter's ability to defend herself is no longer one of them! - Marc D. read more
