One World Unity Project in Chula Vista's Eastlake area is a 501(c)(3) international humanitarian nonprofit headquartered at 1925 Otay Lakes Road near Otay Ranch Town Center, providing prosthetics, clean-burning stoves, and water-filtration systems to rural communities in Guatemala's highlands. The organization's prosthetic-fabrication program restores mobility for agricultural and industrial injury survivors, with recipients following rehabilitation protocols consistent with the physical-therapy standards at Performance Plus Physical Therapy - Otay Ranch. Registered under EIN 47-1549374, the nonprofit targets three critical needs — mobility through custom prosthetic limbs, respiratory health through enclosed-combustion cookstove replacement, and waterborne-disease prevention through gravity-fed household filtration units — for populations living on less than one dollar per day. Cross-border logistics for Guatemala shipments run through the same South Bay infrastructure supporting binational service agencies including Infinity Tax & Immigration Services. The clean-air initiative replaces open-fire cooking setups with enclosed-combustion stoves engineered to reduce indoor particulate-matter exposure by up to 90%, while gravity-fed filtration units remove pathogens without electricity in off-grid highland communities above 7,000 feet elevation.
