EPSO was founded in order to meet a more specialized demand from customers. EPSO is not simply the largest boutique in the Outaouais region, it is the most specialized in this field and gets the highest satisfaction rate in the region. EPSO also relies on the diver community by partnering with the region's largest diving club, Eau Zone. EPSO has a very high standard of quality for all services. We are the only shop in the Outaouais region to certify(and display) the air quality of our compressor.
