Marsha is a very polite, honest, and professional manager. My husband and I had a moving company placed our belongings at the facility, and we wanted to check on our items. The company did a terrible job loading all of our personal items into units and my husband had to find a solution to get one if the doors to lift up, but the way the movers logistically placed our items, we were having issue trying to get the door to open. Marsha was very patient and helped whatever and however she could. Once we got the door to open and did some rearrangement to avoid running into the same issue in the future, Marsha explained her process to let us know that our belongings as well as those who rented or will rent a unit from her facility are and will be secure and safe. She walked us through the process. We even watched her explain where to go and what to do with other unit renters. You can tell she takes pride of her facilty and her occupation as a manager. Thank you, Marsha!

Your positive experience with Marsha is greatly appreciated. Thank you for sharing your feedback Kim.
