I called this company to get some questions answered, not to use their services. The young lady, Catrina, was extremely helpful, pleasant and one could tell she enjoyed her job. Most places, if you are not going to employ them, would just be curt. I am sure that Catrina's attitude represents the attitude of all their employees. If you live in Northern or Central Calif., use these folks for your hazardous waste disposal. Her advice saved us money. Thanks from Carol Figone and Joan E Teunissen Oakdale, Ca
