Russell has always been interested in technology.  He built his first computer in 1995 and started coding HTML and C shortly after.  Shortly after college he was an early team member at a small data recovery company in Austin, TX where he met co-founder Damon O’Connell.  He helped grow the company through name changes, investments, and large corporate eDiscovery cases.


When the new company decided to get out of the data recovery and forensics world, he reached back out to Damon to see if he was interested in getting back into it and the rest is history.

Russell has been responsible for streamlining the data recovery operations through the development of internal processes and tools to manage cases throughout a data recovery case. Russell began some of the first R&D on NAND flash recovery techniques in the industry back in 2005 in order for Flashback to become an industry leader with SSD and flash memory.  As the company has grown is Digital Forensics presence, Russel extended his data recovery knowledge into the forensic world and is currently a Certified Forensic Computer Examiner (CFCE) and peer review coach for the CFCE process.

Russell is former University of Texas swimmer, National Champion and former American record holder.  He currently enjoys rock climbing…

Ever since I got my first computer I became absolutely fascinated by them and how they worked.  I loved to take them apart and fix them up.  Once I got into the real world, I was given an opportunity to work in the data recovery industry.  This is an industry I did not know a lot about, but it sounded intriguing.  So, for the last 24 years I have been working in data recovery and growing my knowledge in getting clients back their data, and their peace of mind.  Having worked with over 24,000 hard drives, countless mobile phones, tablets, tapes, and dvds — you name it — I consider myself one of the top data recovery specialists in the industry.


Knowing that I am able to help people save their businesses from failing, recover pictures of a past relatives, weddings, special days, and even students’ dissertations is what keeps me doing this every day.

I started my career at Ontrack and learned everything from the basics to higher level specialties. Through the years I have continued to gain a plethora of knowledge in industry research and trying new techniques, and with spending the last 14 years at Flashback Data, the learning continues.





In the playing field of forensic digging, Matt is our captain — and he digs deep. Matt Danner started his career in 2008 as a fraud and public integrity investigator in the special investigation units of the Texas Workforce Commission and the Texas State Auditor’s Office.  During this time, Matt conducted hundreds of investigations related to complex financial schemes and coordinated investigations with federal law enforcement. If there’s one person who can get to the bottom of almost any sticky situation, it’s Matt.


His street cred speaks for itself, and so does his knowledge of computer forensics. He began his career in digital forensics in 2012 at the State Auditor’s Office in support of the investigation unit.  In 2016, Matt accepted the lead forensic position at the Flashback Data, LLC as Senior Forensic Examiner. Not only does Matt conduct forensic examinations, but he also directs the operations of the Forensics Division with Forensic Case Manager Stacy Kazmir.

As our Senior Forensic Examiner, Matt works with a wide variety of clients to include law enforcement, criminal and civil attorneys, prosecutors and defense counsels, corporations, and private citizens. His common areas of examination include intellectual property theft, criminal defense, homicide, child exploitation, vehicular accidents, fraud, and family law. If the evidence is there he’s going to find it. Matt has testified as a digital forensics expert numerous times in state, federal, and military court, and he frequently conducts presentations to various government, legal, and educational organizations.

In his spare time, Matt enjoys jogging with his labrador Major and riding his motorcycle in the hill country.
