    Victoria from bio-one of havredegrace MD was outstanding. She is a caring, sweet, hardworking, person. She went into this job thinking of her clients needs, and feelings. Explaining every step of the way, to get approval, to clean out 3 floors of ‘living’ space. It is now very livable. She also works with the animals in the house, to insure their safety. She also stopped at the store to purchase items that my cousin needed, and couldn’t get out to get. She checks up and stops by the house, to make sure everything is still fine, and if anything else is needed. She truly is ‘Gods angel’ on earth.
