Why MPS Security is regarded as the top Professional Security Services & Executive Protection in the nation. 

Extremely professional security group, definitely recommended for security protection. I met a supervisor named Solstad, who represented the company. With their knowledge and background during our risk assessment, we hired them and couldn't be more pleased with their staff and all of our interactions.

Albert Junior Owner

I've worked for many security companies in the past, and MPS is the most organized, giving employees specific direction without micromanaging. Tally Flotron is excellent! She is by the books but always helpful and fair.

Clara Jepsen CEO

All of my interactions with this company have been professional and high quality. I recommend them for all of your security needs. They have operations in multiple states.
