25 Years of Investigations


25 Years of Private  Investigations in Jacksonville and Orlando FL

Mulholland Investigation took their first case in August, 1996, from a spare bedroom in our founder's house located in Jacksonville, Florida. Sean explains, "it is quite rewarding to look back at the journey. There are so many family members, friends, staff members and clients to thank, but the support of my wife and children has been the foundation of our success."


The world is a very different place today than it was 25 years ago. The digital age has created an explosion of new needs for cyber security and the advent of social media and cell phones has provided immeasurable opportunities for surveillance cases. Our Computer Forensics Division was initiated seventeen years ago, and today we image and analyze computers and cell phones, but conduct more social media research and forensics collection then the traditional methods combined. Our attorney, accounting and medical clients are faced with ever-increasing regulatory compliance demands which have enabled our firm to expand our offerings to offer clients Cyber Security Training and Vulnerability Assessments. We may have begun with straight-forward investigation cases, but today provide a full-service agency with experts in a variety of services:

Sean continues, "it is incredibly rewarding to see how far we have come, the staff we have grown, and the agency we can offer clients. More than 75% of our staff has been here over a decade, they believe in the work we do and our mission to be there for each and every client." 25 years, hundreds of clients, countless surveillance/ investigation scenarios and millions of dollars saved, Mulholland Investigation is proud to offer quality service nationwide and is delighted to celebrate this milestone anniversary.


Whether you have hired us before, or are considering us for your next case, we are here, we are experienced and we are eager to help. We look forward to the next ten years and will continue to provide our clients with professional investigative, computer forensic and security consulting service. Thanks to all for their support.
