a word from a valued client
David Jones
Perfexia Inc.

We started working with Clarke Starke & Diegel LLP in late 1999, just prior to our purchase of a small manufacturing company. The firm assisted us with some initial analysis, the due diligence and guided us through the acquisition process right through to closing the transaction. They have acted as our external accountants ever since. In addition to our year ends and tax returns, have always been able to assist with strategic tax advice and all general accounting questions we had. Over the last 18+ years, Clarke Starke & Diegel LLP has also assisted the company with several real estate transactions, amalgamations, a company valuation as well as some shareholder transactions. I can very confidently Clarke Starke & Diegel LLP as professional accountants.
