Entrust Accounting & Advisory Services


Meet our Principal.

Unlike many small business accounting firms, we provide a holistic business approach to understanding your small business accounting, tax, and finance requirements as our focus is not just on your historic results. Through our advisory services, you can learn to better manage, control and plan so you can improve your forward-looking long-term results.  


Giving a Presentation


  • Having hands-on working experience working not only within businesses as well as in an advisory capacity provides a unique set of skills. In addition, that experience and expertise include other areas outside of finance and accounting including engineering, manufacturing & operations, and sales and marketing.

In 2001, we moved to Toronto where I worked for telecommunications, financial, and software as a service  (SaaS)  providers such as Sprint Canada, Rogers Communications, and Everlink Payment Services, where I held executive roles in Marketing, Product Management, IT Professional Services, and Sales.

In 2010, became a partner in RK Fischer & Associates, which is a business coaching and consulting firm that focused on helping small businesses solve business problems while delivering value and creating growth through solutions that help businesses move forward and become profitable.

In 2012, under RK Fischer & Associates, I took on Accounting and Finance roles for small to medium businesses in Ontario. In addition, I worked as a delivery consultant for the Business Development Bank of Canada where Iprovided financial management and financial performance improvement engagements.


In 2016, I attended and become certified under the Certified Value Builder™  program that provides consulting professionals with the know-how to guide business owners in practices that will help them increase the value of their business.

In 2017, returned to Sarnia, where I have continued consulting and coaching as a partner of RK Fischer & Associates as well as taking on several controller roles for companies in Southwestern Ontario.  In addition, I taught courses in business at both Lambton College and Fanshawe College.

In 2020, I started Entrust Accounting and Advisory Services so I am able to offer compilations and tax services to the public which was not possible under RK Fischer & Associates, as it is not a CPA firm.
