I like to use Google Search and it is the most popular method or service used. Today over 90% of all search traffic comes from Google. If you search for many terms like local CPA, or CPA near me, the results you will see first after or sometimes even before an ad is called the map pack. A map pack result starts on the main search page, showing the top 3 listed providers in the area closest to your location. Visit their Google My Business listings that power these map pack results, then also visit their website.
It's important to make sure the person you find is actually a Certified Public Accountant. When searching, you'll want to make sure the person you find serves clients in your area. Some CPA firms are smaller local firms, and others offer national or even global services.
