Meet Our Team

We’re the most knowledgeable, caring, and dedicated team of chiropractors, therapists, and coaches anywhere in Denver or San Francisco.

PostureWorks Chiropractic was founded in San Francisco by Dr. Jason Miller and Dr. Scott Levin to serve as a resource center for optimal health and healing in our community. In 2015, Dr. Jason Miller moved back home to Denver, Colorado, and opened the second PostureWorks location in the downtown area.

Both doctors’ passion and incredible drive to spread the message of hope and improved healthcare are evident by looking at their busy schedules. Not only do they run multiple full-time practices, but they’re also instructors for Chiropractic BioPhysics seminars and are professors, adjunct professors, and lecturers at several chiropractic and medical schools, including Life University, Life Chiropractic College West, Palmer College of Chiropractic, Parker University, UCSF School of Medicine, and UCSF School of Pharmacy.

Dr. Scott Levin

Dr. Scott Levin began his higher education at Brandeis University, where he followed a pre-med path while completing his bachelor’s degree in classical archeology and ancient history. His passion for learning and interest in prevention and wellness-oriented healthcare led him to pursue his doctorate from Life Chiropractic College West (LCCW) in the San Francisco Bay Area.

Prior to his chiropractic education, Dr. Levin recognized the tremendous benefits of musculoskeletal care and even became a licensed massage therapist during his senior year of high school. This knowledge of the musculoskeletal system, alongside his desire to understand the intricacies of the human body, propelled him to the top of his class at LCCW. At graduation, he was honored with the distinctions of Summa Cum Laude and Valedictorian.

During his internship and residence at the LCCW Health Center, Dr. Levin’s abilities were recognized by the faculty, and he was asked to serve in the Radiology Department as a mentor for other interns completing their residence. He was later bestowed the 2007 Clinical Excellence Award for his work in the LCCW Health Center.

In private practice, Dr. Levin invited his colleague and business partner, Dr. Jason Miller, to join him in a detailed review of the literature pertaining to chiropractic’s validity as a noninvasive treatment for chronic disability, improving recovery rates, and pain reduction. Dr. Levin posed the question, “If you reduce a patient’s pain while also increasing their quality of life, how much more productive does that person become?”

The focus of Dr. Levin and Dr. Miller’s meta-analysis rapidly evolved to include the effects of pain and disability on the American workforce from a lost productivity time perspective. Their research culminated in the publication of Chiropractic Health Promotions, a referenced prospectus, which demonstrates that the investment of treating pain and disability with chiropractic care not only reduces lost productivity time and absenteeism but also yields substantial returns.

In practice, Dr. Levin’s clinical acumen helps many hundreds of patients each day. He is the co-clinical director of both PostureWorks, an advanced spinal and structural rehab facility that specializes in the evidence-based specialty chiropractic BioPhysics, and NutraWorks, a leading weight loss and nutritional counseling center that specializes in addressing the causes of metabolic syndrome and its component conditions.

Dr. Levin’s knowledge and ability to teach others the value of prevention and wellness-oriented healthcare practices make him a trusted and highly valued member of the San Francisco healthcare community. He considers this to be a blessing and is dedicated to being both a student and teacher for the duration of his professional career.

Scott is currently involved in an outreach program designed to teach parents and children in the San Francisco school systems about lifelong spinal health and proper musculoskeletal development.


Dr. Jason Miller

Dr. Jason Miller, co-founder of both PostureWorks and its sister health center NutraWorks, is a well-respected chiropractic clinician, a certified Chiropractic BioPhysics practitioner and instructor, a nutritional counselor, and an educator.

As a wellness and prevention-based doctor, he is dedicated to being both a teacher and a student for the rest of his professional life. Dr. Miller takes a proactive stance toward health and believes the most important aspect of treating patients is educating them about the natural and effective methods of preventing disease before it begins.

His passion for teaching others has led him to accept a part-time faculty position at Life Chiropractic College West, one of the world’s top chiropractic institutions, and he is regularly asked to lecture for the UCSF Medical Center and Medical School’s Wellness Committee.


Dr. Corey Todhunter

Dr. Corey Todhunter fell in love with chiropractic care after he suffered a compression fracture injury to his spine when he was 17 while weight training for baseball. He hardly left his bed for 3 weeks because of the spasms and pain. He sat out of all sports his junior year of highschool.

He tried many things to relieve his severe pain but didn’t have much progress. He begged his parents to try traditional chiropractic to see if it could allow him to start training for his senior year of baseball. Chiropractic care finally gave him more relief and allowed physical therapy to be more effective.

He continued his baseball career and received a scholarship to play at Colorado Mesa University. He played with the team that gave the school their first Division II College World Series appearance in 2009.

During this time, regular chiropractic care and strength training helped him through his baseball career, but unfortunately his pain condition always came back.

In order to understand more about his condition, Dr. Todhunter began pursuing Chiropractic as a career at Parker University. This is where he found Chiropractic Biophysics research and the technique, which could finally tackle his chronic spinal problem. He underwent his own CBP protocol to fix his spine and has since gone on to receive his Advanced Certificate in Chiropractic BioPhysics.

He now resides as Co-Clinical Director @postureworksSF since 2014.

He believes everyone deserves the opportunity to improve or resolve even the most complicated musculo-skeletal issues that cause limitations in people’s lives and happiness.


Dr. Jessica Lewis

Dr. Jessica Lewis received her Doctorate from Life Chiropractic College West in June of 2020. Dr. Lewis’s journey and experience with chiropractic began well before she began her Doctorate education.

As a three-sport high school student athlete Dr. Lewis benefitted from chiropractic team doctors, however at the time she did not know the difference between chiropractors and ATC or medical doctors. Beginning her Interdisciplinary undergraduate degree in Nutrition and Public Health at University of California Berkeley, she wanted to study the functionality of the body.

While at Cal she also increased her activity level and began playing rugby. Playing such a physical contact sport, Dr. Lewis found herself increasingly needing more holistic care. She found solace in Cal’s team doctor who counseled her on how to stay healthy and optimize function. This doctor was a chiropractor. Dr. Lewis’s nine-year rugby career has included selection as a USA Rugby All American, a Northern California All-Star, and she has won three USA Rugby National Titles with Life West Rugby. She attributes her health throughout her rugby successes, and her ability to continue playing rugby, to chiropractic care and methods.

Dr. Lewis knew she wanted to pursue an education in the practice that contributed to her healthy lifestyle and jumped at the opportunity to study chiropractic at Life West Chiropractic, after being offered an academic scholarship to play rugby for the college. During her time at Life West, Dr. Lewis suffered a back injury and found that the care plan that was most effective for her included CBP. Dr. Lewis found a passion for the specialized study of CBP and pursued both an internship and preceptorship in CBP.

Dr. Lewis is extremely grateful to be part of the PostureWorks team and excited to help her patients benefit from a holistic healthy lifestyle and CBP care to live their optimal life.


Dr. Negar Navid

Dr. Navid received her bachelor’s degree in genetics from Rutgers University prior to attending Life Chiropractic College West, where she completed the Doctorate of Chiropractic program at an accelerated pace.

During chiropractic school, Dr. Navid took a particular interest in applied nutrition and metabolic disorders, and to this day, she has continued to expand her understanding and mastery of this vital aspect of human health and vitality.

Dr. Navid is excited to be an integral part of the changing landscape in healthcare towards lifestyle improvement and the natural methods of avoiding or resolving many chronic illnesses. She is both a dedicated chiropractic clinician and an inspired role model to all those around her as she strives to do her best for her patients and to live a life full of health and happiness.


Dr. Jonathan Warren

Dr. Jon Warren was born and raised in Southern California, the oldest of two brothers. In his youth, he spent much of his time outdoors with friends, playing baseball, bike riding, and at the beach. This active lifestyle was very important in forming the foundation for his passions for health and wellness.

After high school, he attended Sonoma State University where his interests in health and the human body truly blossomed and he went on to earn his bachelor of science in kinesiology. As he was exploring career options near the end of his time at SSU, he discovered chiropractic and was quickly drawn towards it.

Graduate school was one of the most challenging and rewarding experiences of Jon’s life. Halfway through the curriculum upon reaching the clinic and beginning to treat patients was when the gravity of this type of care really sunk in. Making connections with his patients and watching their improvements while under his care really helped him keep his focus on the big picture while enduring the rigors of graduate school.

During Jon’s last year at LifeWest, he took a class in Chiropractic Biophysics where he was exposed to a more analytical approach to patient care. As this specialization was fully backed by research and very consistently afforded patients long term benefits, it lit a fire within him and gave him the ultimate goal of working in a CBP office so that he could help as many people as possible achieve long term health goals.

Shortly after that, before graduation in the fall of 2018, Dr Warren was offered a position as a resident doctor at PostureWorks in San Francisco and he did not hesitate at the chance to join the team that he is still apart of today
