Dr. Irene Londer

Dr. Irene Londer has been committed to helping her patients live healthier lives for 25 years. Her passion for helping people break free of pain & return to optimal function and performance at work and home, started at an early age. Volunteering at Coney Island Hospital in NY, local nursing homes and pain management practices triggered her interest in working on the human body to restore health utilizing natural holistic therapies. After graduating from Temple University, she went on to Pennsylvania Chiropractic College, graduating Cum Laude in 1995. Dr. Londer is an active member of the Pennsylvania Chiropractic Association & American Chiropractic Association and has served communities in South Philadelphia, King of Prussia and Devon Pa. Dr. Londer lives in Collegeville, Pa with her husband and children.

My philosophy of care is based on the belief that my patient’s needs and goals for health is of the utmost importance. Listening to their healthcare concerns is important in working as a team to provide the optimal acute care treatment protocol and then continued wellness care plans. By utilizing specialty techniques focusing on soft tissue and gentle manipulation of the spine, I strive to restore health and optimal function in the quickest and safest way possible. I promise to guide and educate my patients on ways to lead a healthy lifestyle while respecting the body’s natural healing abilities. While the treatment at our office is priority to reduce restriction in motion, spinal misalignments and postural asymmetry, maintaining the progress requires home instruction on not only functional daily stretches and strengthening exercises but proper nutritional habits as well. Providing our patients with the tools to live their lives without interference is what helps us strive to provide our community with the best care.

I am excited to bring to SCHC a knowledge base and treatment protocols to help patients identify dysfunctional patterns in their musculoskeletal system that is holding them in the pain cycle and keeping them from optimal performance.
