Dr. Evan Osar
Dr. Osar is a co-founder of Chicago Integrative Movement Specialists and the co-developer of the Integrative Movement System™ — the lens that shapes how our team works with every client who walks through the door.
A chiropractic physician by training, Dr. Osar spent more than two decades synthesizing what he was learning across chiropractic, physical rehabilitation, sports medicine, and exercise science. What he kept noticing was the same gap from each direction. There were no practical, principle-based resources for the people who needed them most: baby boomers, post-surgical clients, people carrying chronic tightness or discomfort, and the ones discharged from physical therapy still feeling like something was not finished. The Integrative Movement System came out of that gap. It is built on three principles — alignment, breathing, and control — that give us a way to see the client in front of us rather than apply a protocol to a body that does not quite fit.
At CIMS, that lens shows up in every session. Whether you are recovering from surgery, working through an injury, or trying to get back to activities you have struggled to do for years, Dr. Osar and the CIMS team meet you where your body actually is — and give you the strategies to move forward from there.
Dr. Osar is the author of Corrective Exercise Solutions to Common Hip and Shoulder Dysfunction, the Amazon #1 best seller The Psoas Solution, and the co-author of Functional Anatomy of the Pilates Core. He also teaches health and fitness professionals worldwide through the Integrative Movement Institute, the educational company he co-founded alongside his clinical practice.
What clients consistently say about working with Dr. Osar is the same thing practitioners say: he takes information that has felt out of reach for a long time and makes it usable — in your next workout, your next walk, your next ordinary day.
Licensed in Texas and Illinois, Dr. Osar also consults patients worldwide via virtual visits.Â
Jenice Mattek
Jenice Mattek specializes in post-surgery manual therapy and wellness for women and men whose bodies still carry the effects of surgery — often years, even decades, after the fact. Her clients come to her after Cesareans, hysterectomies, mastectomies, hernia and appendectomy repairs, joint replacements, and other procedures, frequently surprised to learn that the pain, restriction, or "off" feeling they've been living with traces back to scar tissue and the under-recognized changes surgery leaves behind.
Jenice's work is about seeing the unseen — the quiet compensations, the restricted tissue, the subtle shifts in how a body moves and breathes that rarely show up on a scan but shape daily life in profound ways. Her path into this work began in occupational therapy, deepened through massage therapy, and has spanned more than 25 years of hands-on practice helping clients return to the activities they need, want, and love to do — whether that's running, lifting grandchildren, traveling without pain, or simply taking a full breath again.
She is the co-author of What Lies Beneath: The Under-Realized Effects of Breast, Abdominal & Pelvic Surgeries, a book written to give patients and practitioners alike the language and strategies they've been missing. As co-owner of Chicago Integrative Movement Specialists and owner of the Integrative Movement Institute, she also teaches massage therapists and health and fitness professionals around the world through conferences, workshops, and her Integrative Movement Specialist Certification.
At CIMS, Jenice's focus is simple: help you see what's been hiding in plain sight, give you the strategies to move beyond it, and get you back to your life.
Sara Fisher
Dedicated in her study of the body, Sara began her professional career as a dancer and continued on to receive her personal training certification in 2002 from the American Council on Exercise. Since then she has furthered her study of the body with a certification in perinatal fitness and a certification as an Integrative Movement Specialist in 2009. As of late, much of her continuing education has included emerging research on hypermobility spectrum disorders and perimenopause/menopause.
Early in her career she co-founded Woman Centered Fitness where she designed and taught several fitness classes for women. Since then, she has been published in various books and newsletters on the topic of posture and movement, and in March of 2017, she and Jenice Mattek released their first book What Lies Beneath: the Under-realized Effects of Breast, Abdominal, & Pelvic Surgeries; How They Affect You; & What You Can Do About ItÂ
Recently, she created a line of pre-recorded movement and exercises products, titled A Joint Effort in Strength Building: from the Ground, Up, where each product focuses on one specific joint region while progressively incorporating a full body workout.
Sara works closely with Dr. Evan Osar, Jenice Mattek, and other healthcare professionals to aid clients in moving beyond their posture, movement, and exercise challenges, thereby bridging their “need” activities with their “want” and “love” activities.
Currently, she sees private clients in their Chicago & Lincolnwood clinics and assists Dr. Osar and Jenice Mattek in teaching other health and fitness professionals in the Chicago area and abroad about the Integrative Movement System approach to identifying, addressing, and changing the suboptimal posture and movement patterns that contribute to a person’s tightness, pain, and/or decreased performance. Whether teaching group classes or working one-on-one, she helps her clients meet their health and fitness goals through customized stabilization and movement strategies. When she’s not doing that, Sara enjoys time with her husband, 2 boys, and the family’s fur baby.
