Mark Donakowski

We make homes and businesses safe and secure by providing complete security solutions. The principal of Invincible Security, Mark Donakowski, has over 30 years’ experience in the security industry. In 1997 Mark started his own company working as an ADT authorized dealer. In order to provide a higher level of service to their customers, Invincible Security ended its relationship with ADT December of 2013. Since then we serve the community as an “independent” security company.

As an independent, Invincible Security is able to provide their customers with personal attention and custom solutions that seem less of a priority with the big name national companies. With direct involvement in the business Mark makes sure that every aspect of a customer’s experience is courteous, prompt and professional. We start by understanding our customers’ needs and serve  them with hi-tech equipment, professional installation, world class monitoring and, if desired, Smartphone access & control. Mark and his family have lived in Douglas County since 1995.
