What is Rejuv Medical?

Joel Baumgartner, MD (Writes to his staff)

I am excited to share with you my vision.  I first want to recap the events that have occurred that have allowed us the privilege to be treating our patients and clients in a manner that creates TRUE HEALTH! We all have a calling in life…An inner drive that propels us to do…to be…to become.  I have always been the type of person that wanted to help others.  That was modeled early to me by my mom in how she made us, and others feel special and valued.  She is, and was always very giving and caring.  She makes those around her feel important and truly cared for.   For me, from a young age I remember being sensitive to the needs of those around me.  I knew in some way I wanted have a positive effect on others and have the ability to influence them for the better.  As my years went on, I grew to also have a competitive spirit and an aptitude for sports and physical activities.  I was a competitive gymnast from age 5 through early college and then competed as a University springboard diver.   I enjoyed being active and challenging myself in any sport I played or learned.   I always enjoyed pushing my body to the extreme of performance.  In college, I also needed the stimulation of the mind, so I challenged myself to what I thought was the ultimate intellectual challenge… to get accepted to Medical School.  At the time, I didn’t necessarily want to be a physician, but needed something to occupy my drive to learn and see what I could do.   I needed a goal and a challenge. Then the day came when the acceptance letter was to arrive at my house…yes a real paper letter.  It came addressed from the University of North Dakota School of Medicine and Health Sciences.  This was the day.   Everything could change.  I was a visual art major with a minor in science and pre-med.  I was going to be an artist of some form (most likely a starving one), and my back up plan if I didn’t get accepted to Medical School was to travel and create art. After tearing open the letter my life took a change in a different direction.  My dad was on the phone.  “Ok dad, here it goes…what will I be…an artist or a miserable medical student?”  The first sentence read, “Congratulations Mr. Baumgartner, you have been accepted into the 1995 Class of the University of North Dakota School of Medicine.   We will be contacting you soon.” …and so the story goes.   Since then much has changed.  The model of healthcare I have created with Rejuv Medical is the future of medicine. I like to call it “REGENERATING HEALTHCARE”.  Before Rejuv, I was working for a large healthcare system in town.   I was seeing as many patients as they could pack on my schedule in a day.  Seeing them for a 5-10 minute office appointment while making a quick diagnosis and getting onto the next patient.  I felt that the quality of outcomes of my services were not optimal. I was prescribing medications to get patients through the pain and didn’t have an opportunity to fully treat them in a complete manner to really create health and real change in their lives.  But then another life changing event happened.  The clinic I was working for decided to leave the area and go back to the Twin Cities.  They were closing in 60 days and I was left to find a new job or pack up and head to the cities.  I had a following of patients and decided to stay here.  I had always thought there is a better way to treat patients.  I had the skills and knowledge to do it and this was my catalyst to make it happen.   I wanted to give my patients the gift of true health, based on sound science and research. My passion has always been repairing and restoring the human body.   It was not an easy road as I started out.  I was in a small 1000 square foot space.  We started out as a fearless three some…my nurse, my receptionist and me.   After about 3 months, I was down to a few hundred dollars in my personal bank account.  I was not paying myself, and if we didn’t see any profit, I was going to have to sell my house or get a loan.  That month we were blessed with our first reimbursement check from Blue Cross.   I still couldn’t pay myself, but at least my 2 employees didn’t have to find another job.  Those early years didn’t stop me…My passion to do things the right way and the feedback I was getting from my patients was all the fuel I needed to keep pushing forward.  As a non-surgical and sports medicine specialist I was doing procedures like Prolotherapy and PRP.   At the time, I was the only one in the area/state providing regenerative options to my patients.  The rest of the medical community at that time wasn’t ready for the wave of the future, but we stood firm in what research was showing us that we can regenerate degenerating painful joints and debilitating chronic disease.  We were definitely outside the box at that time.  Now, we are the box.   What we do with nerves, PRP, STEM cell injections, hormones, and exercise and weight loss is now all backed by sound scientific research.  We believed in our model and now what we do is becoming a new standard of care. Rewind back to where I was 5 years ago.  I wanted more than just getting my patients joints and backs healed.  I needed to restore vitality in my patients.   The standard medical model of medications to treat symptoms and not impacting health and longevity, to me, was a thing of the past.  I needed to rebuild my patients.  It was time to add functional medicine and medical fitness.  My nurse at the time was very versed in hormone replacement and balancing the endocrine system, so together we started to evaluate hormones, adrenals, GI health and micronutrient imbalances.  My patient testimonies where becoming stronger and more dramatic with not only no pain in their old painful joints and spine, but now more energy, zest and passion. Knowing the degenerating effects that poor diet, extra weight and no exercise has on the body I needed to teach and train my patients how to achieve maximal health.   I could only do so much with exercise and weight loss in my clinic.  I could tell them how important it is to get the weight off, but they would also return to my clinic without any change in their overall health status…struggling to lose the weight and uneducated in nutrition.  It was time to create a healthcare model that would be the solution to the healthcare crisis.   I needed to get my patients healthy.   I was in search of my fifth employee…. He was a trainer at Gold’s Gym and was seeing me for a rugby injury that had plagued him for years. In our conversations I discovered that he was unhappy with his personal training job in a “box gym” as he stated.  Around this time, he was about to finish grad school and was talking to me about his desire for a new career. He spoke of his passion to help individuals lose weight, who would otherwise struggle on their own. He loved the show “The Biggest Loser” and how the show utilized a medical approach to help those who were the most desperate.  I was looking at that time for someone that could come into my small clinic and teach my patients how to lose weight, exercise and eat right.  My goal at that time was to combine the science of medicine and the physiology and endocrinology of the body to develop a healthcare model that creates permanent changes and regeneration in my patient’s lives. My patient believed in my mission and he became my fourth employee.   His name was Jerry Ray.   JR joined my clinic and we converted an exam room into a small gym.  I wanted to create a model that could turn back the clock, heal degenerating conditions and restore health and vitality to my patients.  We needed to start to teach our patients how to eat right and exercise….and so we did just that! I have always believed that we need to stop covering up the symptoms and start to treat the causes associated with each diagnosis. Cortisone does not repair the painful, arthritic knee, nor does diabetes medication make the disease disappear. Prescribing one medication after another does not fix anything. It was time to abandon the Band-Aids and restore health.  I understood the need to rectify the problems and behaviors that led these individuals to their current health status. The patient with bad knees was helpless until he lost the 50 pounds that was causing the arthritic joints. The diabetic patient was still going to have complications and be dependent on medication if he or she didn’t lose weight and make positive lifestyle changes to reverse the disease that was slowly killing them. My purpose is to make an impact large enough to get the attention needed to change the way the health system operates and decrease the rise in chronic diseases that are killing our patients, families, and communities.  We need to change the healthcare delivery system to focus on prevention and disease reversal and empower our patients to take their health into their own hands through education, exercise and nutrition.  On the Orthopedic side we need to show our patients that the first option should be joint and spine regeneration with PRP and STEM cell procedures and not cortisone, pain medication or surgery.  Everything we do at Rejuv Medical is evidence-based and developed to reverse the risk of chronic disease and the degeneration plaguing our population. In 5 years we have grown and expanded what we can offer, and are building momentum for a viable and long-lasting entity that will help society rebound from the current healthcare crisis.  We have gone from 3 to 59 (maybe now 60) TEAM members.   We have assembled a TEAM that is full of talent and passion and I believe shares my same mission to change people’s lives for the good.   As for my vision, we will continue to be pioneers and leaders in Regenerative Medicine and Medical Fitness.  We will continue to challenge ourselves to improve what we do, organize our approach and perfect how we deliver it.  We will strive to create an environment that our fellow employees feel valued and respected.  We will support each other to achieve personal goals and pick each other up when they need some help.  Rejuv is a TEAM.   That means we have each other’s back.  We put ego aside and work to create a corporation where we can grow personally and professionally while making an enormous impact on those we serve.  We will continue to be leaders in our fields and create a system that will change the delivery of healthcare into the future.   We will be aware of changing trends, but will stick to the systems and foundations that are solid and tested. I am honored to have such an amazing crew onboard!  I value each one of your contributions and the work you do to make things efficient and a valued experience for those utilizing our services.  You all have the ability to affect the lives of those we encounter every day.  Every conversation, training session, clinic appointment or even just a passing hello, is an opportunity to create an experience for those that entrust us with their care. We all have a lot to look forward to as we continue to grow and touch the lives our patrons! Thanks for all the hard work, late nights and “sweat”.    Let’s continue to work so well together as a TEAM and continue to grow closer to a new healthcare model!
