I moved to Bartlesville after being medically retired from the military and had to look in Owasso for a climate-controlled storage unit. Ms. Joy, the manager, was really amazing. She is very courteous, professional, and personable. She let me know what she had available for what I needed, and we took care of everything over the phone and through e-mail. It was so seamless! Also, this was my first experience with having climate-controlled storage...I stopped by different times throughout the year putting things in and taking things out...the temperature inside was always perfect. I never had to worry about my belongings being damaged. The coded entry always made me feel more secure as well. Outside and inside the facility was always very clean and well-kept. You can tell they take pride in their business and care about their customers. They also have military discount and auto payments!
