“ I’ve been working with Kaz for a few months, and he’s proven to be an effective, detail-oriented trainer. I appreciate his background in physical therapy, which he uses to help me target the muscles I want to exercise with small changes to my lifts. He’s easy to get along with and i’m stoked to keep working together! ”

“ Kaz is very knowledgeable and educated in kinesiology. He has the information to alleviate back pain, shoulder pain, and knee pain. He is a wealth of knowledge. If you have suffered from back pain for years he can fix you up and give you pain free living. He is very focused with his training to make sure his clients get the best service and results. He has his masters exercise physiology. He is also very friendly and fun to work with. Training is functional and also fun. He can help you with weight loss and body recomposition as well ”

“ I was referred to a CSCS-certified trainer by my doctor, and it made a big difference. Kaz created a full-body program tailored to my needs and adjusted it each week based on how I was doing. He paid close attention to my limitations, provided helpful reminders and homework, and kept me consistent. I'm not a typical gym person so I appreciated how encouraging he was. I felt supported, not pushed beyond what was good for me ”

“ Finding a trainer who actually gets you, your body, your habits, your head, is rare. Kaz is that trainer.

What sets him apart isn’t just technical knowledge, though that’s deep. He understands how the body works and treats recovery as seriously as the training itself. But he also pays attention to the stuff most trainers ignore: the behaviors, mindsets, and patterns that either support or quietly sabotage your progress. That breadth makes a real difference.

He adapts to where you actually are, not where you’re supposed to be. No inflated expectations, no generic programming. He’s honest without being harsh, direct enough to tell you the truth, grounded enough to make it land well. He’s also genuinely flexible in how he works, responsive outside sessions, and supportive without coddling.

What I respect most is that he practices what he teaches. He’s a walking example of sustainable discipline, someone who’s put in the long work himself and carries the self-awareness that comes with it. He’ll tell you about his own failures and how he reframed them. That kind of authenticity is hard to fake and harder to find.

He brings real energy to every session, the kind that feeds the room, and a genuine passion for this field that shows in how he engages with it. Being around him makes you want to work with your body instead of against it.

If you’re looking for short-term results and hype, he’s probably not your person. If you want someone to actually build something lasting with, stick with Kaz. ”

“ I got into working out last year (for the first time in my life) and did not really know what I was doing. I decided to look for a trainer and found Kasra online. He worked with me to build a very solid foundation for working out and went out of his way to tailor my routines to my goals/lifestyle.

I really enjoyed that he took the time to explain the physiology and science behind workouts and nutrition so I could understand the "why" of different routines.

Additionally, he was able to offer a lot of flexibility for me when it came to working out. I have a pretty busy work schedule and he was able to work around it.

Overall, Kasra is a great trainer, very personable and very knowledgeable! I would recommend seeing him if you want to build a good foundation or really understand how to workout properly and reach your goals! ”

“ I can’t recommend Kaz enough. I’ve known him for about 10 years, but only trained with him for the last 6 months—and I’ve seen more progress in that time than I ever have before.

My main goal was rebuilding muscle after having my kid, and Kaz has been so intentional about helping me get there. I’ve always worked out, but never had results like this until I invested in a knowledgeable trainer. Kaz has his Master’s in Exercise Physiology, and you can tell—everything is thoughtful and actually works. I also love that he checks in monthly to go over progress, talk through goals, and adjust my plan based on what I want to focus on.

I’ll be honest, I’m not the easiest client. I’ve had migraines since I was eight and some shoulder issues, so while I’m disciplined, I definitely have limitations. Kaz has been amazing at working around those while still pushing me to get stronger.

I’m an exclusively online client, so it was really important to me to have a trainer I could actually access—and Kaz delivers. He’s available for constant communication and sometimes even checks in daily to see how I’m feeling, how my workouts are going, and how my nutrition/macros are on track. He keeps me accountable, encourages me, and also gives the hard truth when I need it.

As a full-time working mom of a toddler, I really appreciate how realistic and structured his approach is. If you want real results, it’s 100% worth the investment—Kaz is the best ”

“ I came to Kasra with L4-L5 degenerative disc disease and a serious accident that left me with almost no use of my left hand (except my thumb). I honestly thought my gym days were over and that I’d never be able to safely strengthen my back again. Kasra completely changed that for me.

From the very first session, his knowledge and expertise stood out. He truly understands how to work around injuries and limitations instead of pushing through them. He’s created workouts that are both effective and safe for my back and my hand, many of which I would have never thought of even when I was younger and working out regularly. The creativity and attention to detail in every exercise have made a huge difference in how my back feels and in what I’m able to do physically.

Kasra is patient, encouraging, and genuinely invested in my progress. Thanks to him, I’m back in the gym, getting stronger, and feeling more confident in my body than I have in years. If you have back issues, injuries, or just need someone who really knows what they’re doing, Kasra is absolutely worth it. I can’t recommend him highly enough. ”

“ Kasra is a first-class trainer. One would have to search far and wide to find such fine technical instruction, attentiveness to the goals of clients, focus towards overall physical health, criticism that is always constructive — as Kasra offers.

I began working with Kasra weighing at ~230 lbs and finished four months with him having lost about thirty. With Kasra I developed a confidence in my ability to exercise both safely and with intention.

Fantastic trainer, an excellent investment. ”

“ My experience with Kasra was invaluable. Life passes you by and you don't realize the effects of it until something triggers you to reflect. I had always been very athletic and active and then I started a corporate life and got consumed by the routine. It wasn't until my health started to be affected that I realized what had happened. Being someone that doesn't usually ask for help I said I could do it on my own. But times had changed, I no longer had the time I did in my young adulthood or motivation. I realized I needed help and that's when I turned to Kasra. He help instill discipline, consistency and effectiveness with the limited time I had in my day. Guided me back to healthy nutritious decisions and eating habits along with strength training and cardiovascular activity. And well the results were more than evident. I would beyond recommend you to give Kasra an opportunity to help you as well. ”

“ I've been through fewer than a dozen workout sessions with Kasra and already I feel transformed.

Kasra focuses on maintaining proper form and balance in my pursuit of hypertrophic muscular development. His repertoire of exercises is amazing in its breadth and effectiveness.

Kasra is a clear communicator and a careful listener. Initially, he performed a thorough and thoughtful assessment of my workout history and goals.

He has intuitively applied this extensive knowledge, gained from study and broad experience in fitness training, to maximize results while always delivering an enjoyable training experience.

Workouts are varied and challenging, but always carefully calibrated and tailored towards achieving the results I'm looking for. I've noticed lasting improvements to my body after every workout.

I can't exaggerate my satisfaction in working with Kasra! ”

“ First time working with PT. Kaz is very professional and provided insights into all areas of working out and nutrition. Everything was clearly broken down from the nutrition piece to the work outs. The application tracks all the food and specific work our plans. Highly recommend using Kaz. ”

“ Working with Kaz has been an awesome experience. As a guy in my 40s who still plays soccer regularly, I needed a trainer who understood balance, building strength, improving mobility, and avoiding burnout or injury. Kaz nailed it.

He’s incredibly flexible and always tailors workouts around how you’re feeling that day, while still pushing you to get better. What sets him apart is how much he teaches during each session, you leave knowing more about your body, your form, and how to train smarter.

If you want a trainer who really gets what it means to stay active and strong as you get older, and who’s just an all-around great person, Kaz is your guy. Can’t wait to get back to it with him soon. ”

“ Kaz has been incredible in helping me rehab an old dance knee injury. Through consistent training sessions, we’ve focused on strengthening the area and reducing pain, and it’s made a huge difference. I’m moving better, and finally feeling more confident with my knees. Highly recommend Kaz for anyone recovering from an injury or looking to get stronger! Also my dog loves him so that's a huge plus! ”

“ Talk about a wealth of knowledge. I was fortunate enough to work with Kaz for two years and not a single training session was wasted. There was always something new to learn, but most importantly Kaz always provided the explanation as to why we were doing what we were doing. His credentials and his conviction make him an irreplaceable asset to anyone's fitness journey. I was significantly stronger, leaner and more mobile through our time together. Highly recommend for anyone who values the importance of getting results while learning how to ultimately be self-sufficient in the future. ”

“ I can’t recommend Kaz highly enough! He first worked with my son, a high school athlete recovering from a lower back injury. Kaz’s knowledge, patience, and personalized approach made all the difference. My son not only healed but came back stronger.

After seeing those results, I decided to train with Kaz myself, and it’s been one of the best decisions I’ve made. He’s helped me build strength and confidence through customized workouts, accountability, and advice that extends beyond the gym. I especially appreciated how he checked in with me outside of sessions and offered great guidance on nutrition.

On top of being an excellent trainer, Kaz is a true sports buff—he’s got some amazing fantasy football insights and always kept our sessions productive and fun. We’d often talk about sports, food, and tech while training, which made the time fly by.

Kaz is the real deal—whether you’re a busy professional trying to fit fitness into your schedule, an athlete looking to improve performance, or someone just wanting to live a healthier lifestyle, he’s the trainer you want in your corner. ”

“ Kasra is an excellent all-around trainer.

His numerous years of experience have clearly made him a cut above the rest. He’s been able to help me develop my strength, improve mobility, and better my overall confidence in the gym. Whether you’re a novice or long-time athlete, his programs will help you take you to the next level.

“ I met Kaz back in 2013 just as I was halfway through my Sophomore year of high school. I weighed maybe 115lbs and had nothing but experience playing soccer and the heart to be great. A few months into my new gym l stumbled upon Kasra, who was one of the trainers there at the time. After my assessment with Kaz, I came to the conclusion that I needed professional help. He took me under his wing and not only trained me but became my fitness mentor. Everything from nutrition to workouts to recovery, Kaz had quality advice for, and I am forever grateful. If you're looking to invest in a trainer, look no further.

P.S. ever since i've met kaz, i have not been entirely out of shape. ”

“ I could not recommend Kaz as a personal trainer enough. He's incredibly professional and passionate about teaching the right way to train. Instead of just pushing me through workouts and lifting heavy off the bat, he spent time explaining proper form and the importance of recovery. He also helped me understand the importance of a well balanced nutrition plan and gave me examples and macro goals. After years of trying to work out on my own, I finally feel like I have a solid foundation and the confidence to hit the gym. I recommended him to my Dad and Kaz was excellent at adapting to his specific goals, too. ”

“ I am a 78 year old male.

I enjoyed a relatively labor intensive 40 year career.

I developed problems with my back, knees & shoulders.

I worked with Kaz for two years before he relocated to Southern California.

My flexibility & mobility in all areas improved tremendously!

Kaz is very knowledgeable & communicates that knowledge very effectively!

He is patient, thorough & reliable.

He encourages feedback & really listens to clients concerns & goals!

I recommend Kaz to anyone wanting/needing to improve strength, flexibility & mobility! ”

“ I've been training with Kasra for over seven years now, and honestly, it’s been a game changer for me. From day one, he took the time to understand my specific needs, especially when it came to physical therapy and rehab.

Kasra really knows his stuff when it comes to anatomy and injury prevention. After dealing with a few injuries, he crafted a program that not only focused on building strength but also on improving my flexibility and mobility. I’ve seen incredible progress in my recovery, and I appreciate how he’s adjusted my workouts as I’ve improved.

Nutrition is another area where Kasra shines. He offered me practical tips and created a personalized eating plan that fits my lifestyle and goals. It’s made a huge difference in how I feel and perform, and I’ve learned so much about fueling my body the right way.

If you’re on the lookout for a trainer who is knowledgeable, supportive, and truly invested in your journey, I can’t recommend Kasra enough! ”

“ Kaz was my personal trainer for about a year and a half before we had to part ways. I had gotten 2 meniscus tear repairs, a meniscectomy, and a meniscal transplant on the same knee within the span of 7 years. Within a year and a half, Kaz has helped me become the strongest I've ever felt since my injuries. He inspires me to push myself as well as helping me gain confidence in my own strength and abilities again. He made me feel so comfortable. Kaz is reliable and brings the energy to the gym. If you are looking to bounce back from an injury, I advise you to check Kaz out! :)) ”

“ Kaz is an incredible trainer. I have lupus and was struggling to regain strength after a case of Covid. Kaz’s expertise and encouragement enabled me to build stamina, mobility, and strength without ever causing a flare. If an exercise put too much strain on a joint, he would quickly modify; however, he never babied me and I made steady progress. I’m so grateful for Kaz’s help and envious of the San Diego people who will be lucky enough to train with him! ”

“ Kaz is the best! I worked with him through strong times, injury, and returns from extended vacations. Kaz was able to adjust my workouts to get me back on track. Don’t let Kaz’s muscular physique fool you, he knows how to work with us older folks too.

Honest, dependable and well educated in physical fitness (he has a million certifications) you can’t find a better trainer than Kaz. I wish he would move back to the Bay Area. ”

“ I have trained with Kaz for over 5 years and he has been fantastic. I came to him with a newly diagnosed slipped L5 disc and my primary goal was injury prevention in addition to strength and conditioning. With his expert care and guidance I have been symptom free all this time, and have been the strongest/healthiest I have ever been. His experience and education shows in his ability to tailor exercise plans to my needs. He has enabled me to surpass my fitness goals, and I am able to always max out my scores with the Army Combat Fitness Test (now AFT) which I am required to do every 6 months. Our sessions fly by and I always feel accomplished. If you need an expert trainer, Kaz is the right person for you! Also great with dogs - our dog loves him which is the ultimate mark of approval! ”
