top notch attorney
Kevin Costello so kindly helped me and my disabled daughter at a time we felt so vulnerable. His altruism was so unexpected and refreshing and I cannot thank him enough for all he has done for us. All involved including Drake, Robin and Kevin were true professionals and were attentive and sensitive to our needs and case. Thank you so much. I highly recommened Costello and Mains!

Exceeded expectations
Kevin Costello and his team, especially Miriam, exceeded all of our expectations. From the initial phone call, Kevin's passion and interest in our case was unwavering. His belief in our cause gave us the momentum and support necessary to fight a long established institution. He did not hesitate to reaffirm that our case was one worth fighting for. Without his knowledge and guidance showing us the way, we would not have gotten as far as we did. We are forever grateful for Kevin and his entire team!

Miracle Worker
My time was almost out to file a Labor/Employment claim. I didn’t know where to turn. Fate & faith found us Kevin Costello. His HONESTY was profound. His knowledge, ethics & professionalism while remaining just like another person with me made a difficult issue more endurable. Having had the honor of seeing Mr. Costello in action, again, I must reiterate his knowledge, ethics & professionalism during this session. His staff is always kind, knowledgeable & professional. We were Blessed to have found our way to Kevin & his Team!

The Firm is a Joke
This firm is not one of the top rated. They actually post the reviews making people think that they are and are good attorneys. Do not be fooled by the high number of people saying that they are great!!
