My name is Yvonne Boose, I am the founder and president of Sincerity Consulting Firm formed in 2013.

I am a native of Georgia where I currently live. I was an Online Instructor at University of Phoenix for 5+ years and a Facilitator/Instructor for the Associate level FP/101 Foundations of Personal Finance class and the Bachelor level Rev/400 Introduction to Revenue Management (Financial Reporting/Accounting) class.

On campus at West Georgia Technical College I was a Continuing Education & Cooperate Training Adjunct Instructor teaching Accounting, Attitude, Bookkeeping, Intro to Computers, Excel 2007, 2010, and 2013 Level 1 & 2, QuickBooks 2007, 2008, 2009 & 2010, 2011 Level Level 1, 2, and 3, Word 2007, 2010, and 2013 Level 1, 2, and 3 classes for 5+ years.

In addition, for over 20 years, I have worked as a contractor for numerous small businesses assisting with all QuickBooks both desktop and online software, Human Resources, Payroll, and Organizational Leadership needs. My previous work experience included working within the private and government sectors as an Order Administration Manager, Accountant, Budget Analyst, and a Financial Analyst.


“Great at setting up and maintaining budgets!”

My educational background includes an Associate of Applied Science (AA) in Management and Supervisory Development, a Bachelor of Science (BA) in Finance, a Master of Business Administration (MBA) with a concentration in Accounting and Finance, and a Master of Education (M.ED) with a concentration in Organizational Leadership. I started my AA in a classroom setting with some online classes. Having experienced this classroom setting, I completed my BA and both MBA’s online. With taking the online classes, I began to see that I had a passion to become an instructor to assist students with making a difference with their education and success for life.

In 2021, we added freight services to provide cost effective transportation solutions and a variety of transportation options to our customers. Ask about our freight broker and dispatcher service today!
