Expert knowledge, attentive, responsive

I moved out of an apartment recently and checked all of the normal, necessary boxes in doing so. However, the building management company tried to sneak in more month of rent under my nose by lengthening the lease on the digital lease renewal the year earlier, notifying me that I still needed to pay ...one more month of rent even after I had already left. This was sneaky on the part of the management, but what was I to do? Enter John Brennock! He called me back immediately after I contacted him and asked for all the documents he would need to make an informed decision about how to proceed. The end result? I was out of my lease by the end of the workday and the management company never tried to contact me again.

Best Lawyer I Have Ever Hired

I called around to get a price quote from various lawyers in town to review my 13-paged, 36-point rental lease. (I'm a landlord.) Mr. Brennock's quoted price was beyond reasonable; it was awesome. I was also pleasantly surprised by the level of details he went into while reviewing my lease. He was... smart, knowledgeable, and generous. I made multiple changes to my lease based on his recommendation and emailed him a final revised version of the lease for him to take a look, half expecting he would not reply since it was beyond the time I had paid him. But a couple days later, he replied and fixed a few more things for me. This is a great lawyer. Best money I've ever spent.

Excellent, honest, generous attorney

My wife and I got to know John through his father, Mike, who is a long-established Chicago attorney. Mike had helped us with a few real estate closings. We later hired John to help us with some legal issues related to our commercial rental property. John reviewed the lease, detailed our options, and... represented us in court. We were able to get satisfaction on some back payments that the tenant owed. John Brennock is a smart and professional young attorney. He is thorough and spends as much time as needed to get to know the case and understand the legal issues in depth. He is responsive, swift to return calls or emails. We strongly recommend John as an attorney who is competent, generous, and has strong convictions.

John made lease termination so easy

John is very responsive and knows very well about tenant rights. I talked to him over the phone about my dispute with landlord then he asked me to email him my lease. Five minutes later, he called me and told me that I could terminate the lease early without any penalty. During my first visit to his ...office, he showed me the problems in the lease in details and explained to me what I could do. He drafted a letter to the landlord on my behalf and the dispute was settled immediately. Highly recommend John to anyone who needs a lawyer .

Lease Termination

At very short notice and without previously working with John, John talked me through over the phone, the different circumstances my lease could potentially be terminated without incurring financial penalties for breaking the lease. Within the same morning of me forwarding the actual lease to John..., he was able to determine a condition under which my lease could be terminated, drafted the the termination letter on my behalf and later the same day, get agreement from my landlord's lawyers that I could legally terminate the lease. I was in situation where I had no choice but to terminate the lease and prior to talking to John, it appeared that I was going to be stuck with a large financial penalty for terminating the lease. However, John was able to find the remotest of reasons why I could legally terminate the lease without incurring any financial penalties John was personable, knowledgeable, attentive and very responsive to my situation and requests
