Mark Petersen - COO

As Chief Operating Officer at Prosperitas Financial, Mark Petersen leads the company’s business operations with a focus on technology and marketing.  As a child (who idolized MacGyver), Mark was the stereotypical engineer who was known to take items apart just to see how they worked.He has a unique talent of seeing things from a different perspective and he strives to make systems and processes more efficient and effective for the Prosperitas team.

Shortly after graduating with a bachelor’s degree in Economics from the University of California at San Diego, Mark began his career in the Life and Health insurance industry.  During his insurance career, he developed new innovative insurance benefits, helping to accelerate growth for the company while expanding benefits for consumers. With a passion for technology and marketing, Mark helped update and redesign some of the antiquated marketing material and eventually became an award winning graphic designer and the head of the marketing department.

Mark has been happily married for more than 15 years and has two sons and a daughter.  A true family man, Mark enjoys traveling/camping with his family, coaching his kids sports teams, dirt biking, cycling, and playing video games with his kids (more so before they were able to beat him).

Mark is very excited about collaborating with his talented and dedicated colleagues to bring the best service and products to Prosperitas’ wonderful clients.
