Center for Happy-NESSS
About
The Center for Happy-NESSS is a functional medicine practice in Crystal Lake, Illinois, that treats hypermobility spectrum disorder, hypermobile Ehlers-Danlos syndrome, and overlapping conditions common in connective tissue patients, including autonomic nervous system dysfunction, autoimmunity, and mast cell activation syndrome. The clinic takes a "treatment over labels" stance, combining clinical evaluation, genetic testing for connective tissue disorders, and a lifestyle-forward care model that addresses nutrition, movement, sleep, stress, and social relationships. Joint protection is prioritized over surgical intervention, and patients are typically connected with a broader team that includes physical therapy, occupational therapy, and orthotic specialists. Movement recommendations draw on Pilates, Feldenkrais, yoga, and meditation, with dietary guidance framed around "Food as Medicine" principles. The practice operates as a cash-based functional medicine clinic.
