2 great experiences
Mr Zeller has represented me twice. Once in a bankruptcy case where we were owed $200k. We didn't anticipate collecting anything at all. However Mr Zeller was able to collect a significant amount of the balance. The 2nd circumstance revolved around negotiating a lease assignment, in which the landlord was being difficult. He was able to get the lease assignment completed which ultimately turned into the sale of our business. We wouldn't hesitate to use him or recommend him in the future.

Overall Outstanding Service
I had the pleasure of hiring Ryan to handle my litigation on a business transaction and I cannot emphasize enough how fortunate I was to work with him. He was more than knowledgeable to my situation, quickly responded to my inquiries, worked professionally with the other parties, and gave me a sense of peace of mind. I would not only hire him again but recommend to others as well.

Highly Recommend. Professional, Friendly and Knowledgeable
I have consulted Ryan on a couple of occasions regarding a case to help me recoup funds from an executed convertible note agreement for an Illinois business. Ryan was very helpful and motivated to assist me with my case. His expertise helped me make an educated decision of the best way to proceed based on the various factors and provisions outlined in the convertible note agreement. I highly recommend Ryan and wouldn't hesitate to contact him for any future litigation cases or consultations.

I really can't say enough
My business caters to law firm owners, so having worked with them so much I understand what makes for a great client experience. Now that I know what it's like to be on the other end, to be the client, I can say that when we come to attorneys like Ryan we are likely in a state of crisis. What matters to us is knowing that someone is paying attention, someone is on our side and on top of informing us about our decisions and how to make the best decision for us. Someone who is responsive, timely, and knows what they're doing. That is Ryan. I can't thank him and the team enough for the way in which they handled my crisis. I am confident that we found the best outcome for me based on my values, goals, and priorities. Thank you endlessly, Ryan & team.

Phenomenal Attorney.
Ryan is truly the best attorney I have dealt with. His litigation skills surpassed my expectations. Communication and response time was the same day with any questions or concerns I had. He took time to review the material I presented him and always gave me his honest opinion. He’s very professional and diligent with his work. I can’t say enough about him.

Will get back to you and take the time to help
Mr. Zeller gave me his contact info and took the time to go over the details of my case. My case might not have been much, 3 other lawyers before I contacted did not even reply to the emails or contact attempts. I was looking more of an attorney's point of view of the facts, which I received from Mr. Zeller.

Intellectual Property Infringement
My company was sent a fraudulent cease and desist and demand for damages in connection with our alleged infringing use of certain software used on our ecommerce site. The opposing intellectual property attorneys were based in California and were known intellectual property trolls trying to scare business out of money. Ryan competently and successfully handled my company's matter denying all claims of any liability.
