30+ Years of Sage & NetSuite Implementations

The Right ERP Partner for Modernizing Your Business Systems with Sage and NetSuite

Founders Story

Our business began in 1991, when Oasis Solutions’ founders envisioned a company that would help local businesses when they outgrew QuickBooks, spreadsheets and Excel. Our goal was to help businesses get the most out of their software solutions and their business by utilizing MAS90 (now Sage 100).

Armed with floppy discs and a dream, Annette Manias and the founding employees lugged heavy computer equipment from client to client, demoing software. Software has changed dramatically since then, but our philosophy has not: putting the people and the process first.
Today, we support Sage 100, Sage Intacct and NetSuite ERP for over 600 clients across the United States.

Meet Our Leadership Team


Aaron Rosenberg

Partner/CEO

Aaron began his career at Oasis Solutions in June 2015 as Director of Business Development and quickly advanced to SVP of Business Development. The leadership team knew he brought a lot more to the table than sales knowledge and brought him on as partner in 2017. In January 2023, Aaron transitioned into the role of CEO.



William Schlageter

Partner/CIO

William came to Oasis in 2002 from a career as Director of Development and joined the Oasis leadership team as partner in 2008. William has a very straight-forward, practical approach that makes him a go-to person for team members as well as customers.



Karen Roberson

Partner/Director of Employee Development

As Oasis’s first employee and partner from the beginning, Karen has played a major role in our success. Karen began her career as a programmer with a couple of Louisville companies. However, Oasis saw another side to Karen, other than a “geeky” programmer. She is skilled in conversation and has a wonderful way of putting you at ease. Her innate ability to listen and make recommendations is an asset to all.



Patrick Johnson

Partner/COO

Patrick joined the Oasis team in December 2015 during our busiest season! With 10+ years of software consulting experience, he jumped right in assisting customers and other team members. In August 2018, Patrick was appointed Director of Operations and just a year later, Patrick was named partner.
