Mattern CPA has been our accountant for 3 years. During this time Clint and his staff have been very friendly, knowledgeable, and professional in guiding us with both our personal and business accounting needs. It is very comforting to have an accountant we can trust who has also become our friend.

Clint has been our auditor at Training Toward Self Reliance, Inc. for the past 7 years, and throughout that timespan, he has proven to be a tremendous auditor of the agency. Clint's' attention to detail, and insightful knowledge of the auditing process, ensures that our Agency is held to the highest standard in accordance with the auditing guidelines that he follows. Clint has tested our internal controls which has helped us strengthen our controls if anything is determined to be needed, tested our reconciled accounts, tested bills and invoices, and many more things that were critical to the agency. Clint tested in great detail the significant volume of our transactions, and Clint''s vigilant attention to all items related to the financials of the agency has been nothing short of impressive and extremely meticulous. In addition to the above mentioned, Clint was consistent and has high quality audit reports. Myself and the agency's Board of Directors are continually updated on the validity and processing of transactions, findings of audit reports, and he always remained ahead of schedule and worked quickly to identify strengths and weaknesses in our financial department. Clint has been a huge contributor as our auditor and he comes with the highest recommendation.
