EXCELLENT Based on 8 reviews Posted on Darci PrattTrustindex verifies that the original source of the review is Google. State had to dismiss charges!Posted on Elect Blake Joseph CampaignTrustindex verifies that the original source of the review is Google. Privileging experience from a critic who has multiple lawyers on different legal fronts, Greg Sperlich sticks out amongst the fray. With a a pragmatic knowledge in law, and most importantly practiced, Greg lays out the ethos and pathos of what it takes to be a litigator in the state of South Dakota. Straight shooter is a cliché when it comes to describing Greg however, if you look it up in the dictionary, there would be his law office and name in bold. Thank you for your professionalism and care on my legal matter. If you read the end, know having Greg represent me made all the difference in this case.Posted on Nicholas McMahanTrustindex verifies that the original source of the review is Google.
