Cant get over how relieved i am to have found this app (think it was mentioned in a podcast i was listening to) I was taking a cardio kickboxing group class 2-3 times a week before this but unfortunately due to my super busy work schedules, im not able to even commit to that anymore, sadly. LUCKILY, this app saved me & i stumbled upon SENSEI JON!🤘🏽🤘🏽🤘🏽 I truly enjoy our 1-on-1 training sessions & he’s literally a dream come true! Ive learned so much & still continueing to learn so much. He has an amazing way of teaching, he’s extremely patient, hilarious, motivating, inspiring, works around my ever-changing busy schedules, VERY knowledgable in muay thai, boxing, kickboxing AND he even recommends random cool stuff that are non-related (Like cool eateries to try out, healthier food options for my dog) Who even does that?! Lol. This guy is the raddest! Hope he never moves out of state or anything crazy like that because best believe im gunna have to follow him wherever he goes!🤣 Thank u for everything, Sensei🙏🏽

I’ve been training with Jonathan for close to year a now and it’s been an amazing experience. Jonathan is extremely professional and respectful. I always feel comfortable during my sessions and that’s something I haven’t experienced in the past. He goes beyond just sessions and keeps me accountable for working out outside of our sessions and making sure I’m eating healthy. He’s also incorporated kicking boxing and I’ve been really enjoying it since he’s also teaching me how to use these skills for self defense in the worst case scenario. I highly recommend Jonathan if you’re looking for a professional, respectful, and someone who will go above and beyond as a personal trainer.

Jon is awesome! He’s not only extremely knowledgeable about kickboxing /MMA, lifting, and nutrition, but his observational skills are on point. He’s able to identify strengths / weaknesses and tailor my workout plans to improve them. It’s always a great time when we’re throwing on the gloves, listening to good music, and getting a solid workout. Would 10/10 recommend him to friends and family!

Have been with Jonathan for over 2 years and honestly couldn't have asked for a better trainer. No other trainer I've had in the past has made me feel like they genuinely care for my health well being. If you need someone to keep you accountable and someone you're really going to learn a HUGE amount from then Jonathan is your guy. He travels to me at home and being a mom of 3 that really helps a ton. Especially since he wears a mask during all of it during these times and cleans and sanitizes everything before and after I use it. He's especially great with kids and training them in anything from Football to Soccer to Self defense and kickboxing classes for my kids. He's currently training my 12 year old to better his skills on the Field as a Linebacker and trains my 10 year old on self defense and kickboxing which is honestly really awesome to see.

Have been with Jonathan for over a year now and have felt a huge difference in the quality of everyday life with my family. Every time we workout he switches it up and is very clear with me about what has to change on my days not training with him and with my Nutrition in order for me to continue seeing a difference. Really feel like I'm getting my moneys worth and then some with Jonathan.
