My first career developed into an Audit Manager position for Pattillo, Brown & Hill in Waco, TX. I was in public accounting for approximately 8 years. My audit specialty was State and Local Governments and Nonprofit entities. I also had expertise in airlines, banking and corporate holding.
My next career was Director of Finance for a large nonprofit organization, Center for Occupational Research and Development (CORD) in Waco, Texas that had a for-profit publishing manufacturing and distribution company. It was here that I chose MAS 90 (Level 1.x DOS) as the solution for this organization and performed my first implementation. I was in this position for just under 5 years.
After stabilizing the information system at CORD, I was looking for a new challenge and accepted a position with the re-seller that sold the MAS 90 system to me, MicroAccounting Solutions in Dallas, TX. They needed someone to manage their Austin, TX office and a Sales Consultant for Central and South Texas.
I left MicroAccounting in 1999 to start my own consulting company about a year after MicroAccounting was sold to a new owner. We started with no leads or clients and closed our first sale 90 days after starting. DeRosa Mangold Consulting today is a leader in Sage Intacct, Sage 100cloud, MAS 90 and MAS 200 solutions.
My goal is for our company to be the best Sage Intacct and Sage 100cloud service provider in the country, not necessarily the largest, but the most responsive that will bring all of our resources to bear, inside and outside of our company, to serve the client.

On her off time, she enjoys keeping company with her family and fostering animals (mostly kittens) who are in critical need of care.
Liz prides herself on being someone who has a wide knowledge of the software packages she uses. Succeeding expectations with her ability to go above and beyond the norm to collaborate and guide those who require assistance.

Mitzi Stockford came to DeRosa Mangold Consulting after running a Peachtree Support Center for ten years. She noticed the market changing and decided to move towards software such as Mas 90 but didn’t have the team to make that possible. After meeting Mike DeRosa 15 years ago she accepted an opportunity to join his firm and became an integral part of our team. One of the things Mitzi likes the best in this profession is the extensive variety of clients she gets to work with.

Gina Dickson joined the DeRosa Mangold Consulting team in November of 2018. She has had a successful accounting career spanning over 25 years that has crossed paths with Mike DeRosa and DeRosa Mangold Consulting over the years.
Gina’s first employment upon completing studies in accounting at Baylor University took place with Pattillo, Brown and Hill, LLP, under the supervision of Mike DeRosa. The experience as an auditor in public accounting brought about great exposure to multiple types of accounting systems and environments. Gina transitioned away from the public accounting arena by pursuing a role with CORD (Center for Occupational Research and Development). At the time, Mike DeRosa was the Controller, and offered her some flexibility in the workplace while Gina’s children were very young. This experience provided her first exposure to MAS 90 and Sage products. During the fifteen years with CORD she was promoted to Director of Finance and continued to choose MAS 90 as the solution for accounting needs.
Seeking new challenges, Gina left CORD to become Controller of PRUF Energy Solutions, a start-up LED Lighting manufacturing company. Implementing new accounting systems and procedures were tasks that provided both challenging and rewarding learning experiences. This allowed her to dive deeper into accounting as it relates to manufacturing processes and workflow. She remained in this position for seven years before taking on an adventure in the Franchising industry. As controller for Restoration 1 Franchise Holding, the fastest growing restoration franchise in the nation, the experience at PRUF Energy Solutions proved to be invaluable in understanding how to implement all new systems and procedures. The years of experience at Restoration 1 provided a greater knowledge and insight as to the changing needs and flexibility required in a fast growth accounting environment.
Gina is excited to bring years of accounting experience to DeRosa Mangold Consulting as their Client Success Manager and has a strong commitment to serve clients with the best accounting solutions to fit their individual needs.
