About Us

501c3 non-profit organization 

Our Founder

“Because of my personal experience of having a missing family member, I am passionate about helping others find their loved ones to regain some hope or closure. Since 2006 I dedicated my life to working directly with Aquatic Ops and Missing Children’s International Ministries to accomplish this.

I started the organization Guardians for the Missing in hopes of bringing more attention to the missing persons cold cases. I am certified by the State of Florida, the National Association of State Boating Law Administrators and the U.S. Coast Guard in Boat Safety. Also a member of the U.S. Coast Guard Auxilary.”

– Alison McManus

What is Guardians for the missing?

Guardians for the Missing is a 501c3 non-profit organization based in South Florida. We provide services to the families of the missing to bring them closure.  

Our main focus is underwater searches for cases of the missing with their vehicles in bodies of water. We work with the families, law enforcement, and other agencies upon request and as needed. We do not offer any legal counsel nor do we charge fees for our services. During our searches, we use our boat with a side scan sonar accompanied with certified divers that are trained in search rescue. Our team of volunteers with law enforcement experience and trained divers will join your family in search of your loved one.

Florida is surrounded by water and full of swap grounds, rivers, and lakes. This increases the risk of elderly and impaired drivers. When all other options have been exhausted and your family is in need of additional resources, Guardians for the Missing will continue the search; cold cases included.
