Renowned sculptor Margot McMahon relied on hiking and biking to stay in shape for her physically demanding work. But when her knee gave out during a hike—just months before leading the Ragdale Tree Project in Lake Forest, IL—she knew she needed a solution fast. Margot chose Dr. Berger for knee replacement, confident in his minimally invasive approach and quick recovery time. Just three months post-surgery, Margot was back to climbing scaffolding, wielding chainsaws, and sanding pain-free as she brought the “Diversity of Birds” tree sculpture to life. Now on display in Lake Forest, her work is a testament to the power of resilience and expert care.
