Chicago Sports Institute provides comprehensive and individually tailored performance training by expert coaches with proven success rates. Here’s are some testimonials from some of our successes describing their experience training with us:
Corey Baker, Pitcher, St. Louis Cardinals Organization & Member of Team Israel in the World Baseball Classic
A teammate referred me to Chicago Sports Institute after my 6th season of professional baseball with the Cardinals. I can honestly say after spending my off-season training with Dave, I am more ready both physically and mentally than I have been for any previous season. Dave’s knowledge of training and nutrition changed my body in just a few months. He not only cares for my baseball career, but for my health in general. I would highly recommend Dave and his staff to anyone who is looking to improve!
Corbin Bryant, Defensive Tackle, Buffalo Bills (Excerpted from video interview)
Flexibility is the biggest thing for me to become a better player and I’m definitely moving a lot better on the field and in drills now… The things Dave incorporated in the workouts helped me develop into more of a complete player….My pop off the ball and my explosiveness have definitely improved in just 3 weeks of training with Dave….I would refer Dave to any of my former teammates or any other professional athletes out there that are ready to train hard and get better.
George D, Avid Athlete
I was referred to Chicago Sports Institute by a friend. I am currently treated as needed by Dr. Jon Sebby at Chicago Chiropractic & Sports Medicine and I train two times a week with John Sandberg. I feel better today than I did 20 years ago. I am playing in paddle tournaments again – and I’m pain free. I know that I would not feel as good as I do today if it weren’t for the collaboration of the medical staff at CCSM and the trainers at CSI. John and Dr. Sebby work together to customize my training and treatment regimen and consult on progress. The combination of the staff is seamless, easy and everyone is incredibly friendly.
I have had 6 knee operations, plantar fasciitis in both feet and a variety of other sports related injuries. After four rounds of cortisone shots the effectiveness started to fade and my orthopedic surgeon told me I would need to have both knees replaced. I started to pre-hab by doing yoga. After one month of doing yoga three times a week the pain I was experiencing decreased but I knew I needed more. A friend bought me a gift certificate for an evaluation and five training sessions with John Sandberg. John was able to assess my weaknesses from injuries and sitting behind a desk for 20 years. John designed a program to strengthen those areas of weakness, specifically in my legs and hips. After working with John for two months, John suggested I would benefit from working with Jon Sebby to work on decreasing years of scar tissue from the knee operations. The results were amazing – a significant decrease in everyday pain, and in increase in my ability to train – and performance while playing sports. Additionally, John and Dr. Sebby have enabled me to reduce in season injuries through off season training programs.
The biggest benefits of the integrative approach with Dr. Sebby and John are that I have not needed the knee replacements – and I am pain free for the first time in years. The combination of working with John to strengthen areas of weakness and Jon Sebby to break down years of scar tissue has reduced my pain significantly and I feel stronger than I did 20 years ago. The staff continues to work together as new issues arise. The combination of having John Sandberg and Jon Sebby under one roof couldn’t be more convenient.
I am extremely satisfied with the results after each session. Each time something comes up I know that everyone will get me back on my feet. I re-tore my plantar fascia playing paddle tennis a few seasons ago and John Sandburg and Jon Sebby had me back on the court in a month.
I have, and will continue, to refer friends and family to Chicago Sports Institute and Chicago Chiropractic & Sports Medicine – there is no better use of time and treasure than to insure your health and quality of life.
“I started training with John Sandberg my junior year in high school, and I have never looked back since. My baseball coach referred me because at 6’2 and 150 pounds, it was obvious I had room for improvement. In just one short year, my senior year of high school, I put on 50 pounds of lean muscle, improved my flexibility, and increased my cardiovascular strength to be competitive at the division I level. In addition to strength training, John has rehabbed me from two major injuries (a spinal L5 fracture and Tommy John surgery). His dedication to his craft is second to none, and his commitment to his client is evident through the elaborate workout routines, nutritional support, and overall fitness advice. John provided a platform to compete and battle the rigors of a division I athlete. The confidence of knowing my body was at a competitive advantage to achieve success led to further skill development and increased performance ability. John has been a constant in my athletic career, and I wouldn’t have it any other way. I would not be where I am today in baseball if it weren’t for John.”
– Max Allen, Georgetown University Baseball
“Training with John has helped me a lot through my hockey career. I started training with him several years ago and the results on and off the ice has been tremendous. Being able to have played in the NAHL and USHL, I’ve learned a lot about how important strength is. This year, playing at UCONN, I feel great about my body’s strength and I’m excited to see the results. Before going to John, I had never Olympic lifted anything or knew how many lifts there actually were. John taught me everything I know about lifting and how it relates to my body in a hockey sense. I feel so much more explosive, stronger, and even more confident when I’m on the ice because of his training style. It’s really helped me in my development and I couldn’t thank him enough.”
– Max Kalter, University of Connecticut Hockey
“I love looking back and remembering where I started off and where I have come. I started off 6’7” 165 pounds before I began working with John and now I am 6’ 9” 230 pounds. John helped me gain muscle while adding several inches to my vertical jump. I have used my strength and conditioning to help make me the best player I could be. I played 2 years with the USA boy’s youth Olympic team. I had gone on after that to play at Pepperdine University and start all four years. John has helped me bring my game to the next level as I recently had a chance to play with the Serbian national team, following which I signed a pro contract with Cannes (French Pro A Volleyball). It’s been amazing to see my progression in the sports of volleyball and I thank John for those gains.”
– Nik Antonijevic, AS Cannes Volleyball
“I started working with John 7 years ago when I was a scrawny high schooler with college and professional hockey aspirations. I did not, however, have the strength to compete at the higher levels. I knew that working on the ice was one thing, but I needed an extra edge to take my game further. After working with John for one year, my success at the AAA midget major level increased drastically and I was offered a spot in an elite junior hockey league. Since then we have continued to work together and my college dreams have been realized and now I am working towards making my professional dreams come true as well. I can honestly say I wouldn’t be anywhere close to where I am today without the help and knowledge of John.”
– Rob Linsmayer, Les Rapaces de Gap, France
“I first started training with John for the purpose of continuing to heal a back injury. John not only helped me recover, but he pushed me to become the strongest version of myself. During my first workout with John, he asked me what goal I wanted to accomplish with my training, to which I replied, “Get my back to 100%.” I have John to thank for helping me come back from the worst injury of my athletic career and for preparing me to be a trainee at the Joffrey Ballet School in NYC. John’s individualized workout programs, extensive knowledge, and enthusiastic dedication ensured steady progress and made for a productive and inspiring environment in which to train. Regardless of if I asked for a 6am or a 4:30pm workout, John was always there, engaged and committed to training me.”
– Sophie Allen, Joffrey Ballet School
Matt Raimo, Pitcher, Manoguayabo & San Lazaro in the Liga de AA, Dominican Republic
Dave Hollinger has always been the one person I have counted on for athletic training knowledge, nutrition, and injury prevention above any other. I trained with Dave from the time I played D1 level baseball to the minor leagues in the Dominican Republic. No one will give you top notch training while teaching you how to take care of yourself better than Dave. He truly cares about making a difference in your performance, and health as much as you care about yourself. He will take you from any level, amateur or professional and he will find a way to improve your game. In my opinion he is the best trainer around bar none.
Susan T, Avid Golfer
In six months of training with Dave (Hollinger), I dramatically reduced my body fat percentage and rediscovered a vitality and energy that I have not felt in years. In my 40’s, I worked out at various gyms or in group classes, and thought the aches and pains and general slowness I felt were inevitable parts of aging. I was so wrong. Training with Dave means training smart and efficiently, and reaching your goals. I also see Dr. Sebby (at Chicago Chiropractic & Sports Medicine) from time-to-time, and the integration of his active release techniques and Dave’s workouts is phenomenal. I’m a golfer, and my driving distances, swing speed, and other aspects of my game are vastly improved.
Tanner Creel, Goaltender, UConn Huskies
Dave’s professionalism, intensity and knowledge in the field is second to none. He pushed me beyond limits I thought I had and brought me to the next level both mentally and physically. After working with Dave this past summer he enabled me to increase my vertical by 6 inches while gaining 13 lbs of muscle. I have trained with many skilled trainers, but Dave is bar none the best at what he does.
“Mike creates workouts that cater to individual needs. For example, I had a pulled hamstring that he worked around while designing my workout plans. That being said, even with a pulled hamstring, he helped me increase my leg strength immensely. Also, being an ex-D1 athlete himself, Mike understands the importance of every session and helped me get the most out of every lift. He never let me slack.
I am definitely satisfied with the results after each session. Everything mike puts on the workout sheet is there for a purpose and he catered each workout to my specific needs at the time: whether it was taking tension off my hamstring by strengthening the complimentary muscles, helping me prevent concussions, decreasing muscle fatigue, etc. The workouts Mike puts me together are tough, and sometimes I feel bad for myself midway through, but I always walk out of the gym knowing I got better.
In the offseason going into my freshman year of college, Mike helped me put on 30 pounds, while decreasing my body fat index. I ended my senior football season at 179, and at the peak of my offseason I was 209. At the same time, I was able to rehab a hamstring issue that had been nagging me for months prior to training at Chicago Sports Institute, and completed my first college season with no hamstring problems.”
– Spencer Cotten
“I’ve been training at CSI for a little over 3 months. I made the decision to train with CSI because I felt my current training had become stale and unproductive. I wanted to be pushed/coached to improve all around athletically and physically.
Working with CSI has help me refocus on the nutrion aspect of my lifestyle. I’ve appreciated putting some structure around my meals and training.
I am thrilled with the results. There is, obviously, the improvement in physical appearance, but perhaps more importantly, I feel like my mental game is improved, as is my strength, and my energy levels are consistently higher.
I would certainly recommend CSI to anyone willing to put in some effort and trust the process. The results are undeniable, and I feel really confident that people of any background could get positive results.”
– Helen Lesser
Bryan Pancich, NHL Referee
Dave prepared me for my first full season working in the NHL. He was very attentive to my goals and with his professional guidance I gained 15lbs of lean body mass over 12 weeks training 4 times a week. I have never felt more confident and prepared for the rigors and physical demands of a season. During the season my training was reduced to once every 7-10 days. This allowed me to maintain my strength, body composition, and most importantly remain injury free.
For over the 2 years David personally trained me, I not only reached an elite level of strength that helped me make the 2010 Olympic team in Long Track Speedskating, but learned more about myself through his expertise and integrity that pushed me to be a better athlete and person. The overall package you get from training with David is exceptional and will make you proficient for life.
“My name is Mike Tauchman and I am an outfielder for the Colorado Rockies. This was my first off season training at Chicago Sports Institute. Having done the same off season program for the past four off-seasons, I wanted to seek out a program that focused on improving mobility as well as increasing lean muscle mass. Throughout the 10 week program, we made significant gains in lean muscle mass and mobility, as well as correcting imbalances in my body. The thing I enjoyed most about the training program was that it was individualized to my body, as well as my sport. James also helped me implement a nutrition program designed to decrease body fat. The end result is that I feel stronger, faster and healthier than previous off seasons. James and the trainers at Chicago Sports Institute are extremely knowledgeable and I would recommend them to any athletes looking to take their bodies to the next level.”
