Motto: Live each day as it were your last and don’t sweat the small stuff.  Love, Love, Love people!
What is the one problem you are best at solving for your clients?
Any issues with our staff, whether it be attendance, attitude, dress attire, schedules, etc…and how to make their operation run more smoothly.  I enjoy learning from them and they appreciate my feedback and learning how DMS goes above and beyond in assisting them, other than just filling a position – our services extend to overall operations and assisting the client so they run smoothly internally.
I enjoy taking care of my house/yard and coming up with organizational ideas to simplify life at home so my husband and I can enjoy doing other activities together and eventually doing more traveling together.
What most people don’t know about me?
I am a Twin!
