Great Business Attorney
I would very highly recommend Lexern Law Group for your legal needs. Oleg is very thoughtful and caring, very professional, respectful, and pleasant. He explained everything clearly as possible to me, and I understood it very well. I am grateful for him and will use him again if I have any questions.

More than a business lawyer -- a trusted partner and advisor
Oleg Feldman really sets a high bar for other business and employment attorneys because he is so proactive, thorough and compassionate. He has been our company's exclusive legal advisor since our incorporation, and has helped us with issues related to employees and contractors, business structure and partnerships, risk prevention and litigation avoidance, and even the day-to-day operations infrastructure components like the creation of a robust contract/agreement between our firm and our independent contractors. I used to think that a business attorney was someone you called when you found yourself in trouble; Oleg has taught me that a great business attorney will help you anticipate challenges as your business evolves and that you never need to experience "trouble" at all. I could not more highly recommend Oleg Feldman for small to mid-sized businesses in Wisconsin and Illinois. I trust him; I am continually impressed by his knowledge and experience; and, what's more, I really like him. If you represent a company that doesn't have inside counsel, you really need to create a relationship with Oleg. It's a strategic move, and one you'll always be glad you made.
