Amanda Ramirez
I sought Sean Griffin's expertise for an appellate case in Indianapolis, and while his legal knowledge clearly shone through, there were areas where the experience fell short. Griffin's background in appellate practice, particularly his recognition in administrative and public law, was evident in the way he structured our arguments. However, communication could have been more timely—emails often took a day or two to receive a response, which added unnecessary stress. The wait times between updates were also slightly longer than I expected, given his proven track record. That said, Griffin's dedication to the case was apparent, and his arguments were well-researched and persuasive. If you're looking for a competent attorney with strong appellate experience, Griffin is a solid choice, but be prepared for a slightly slower pace in communication and updates.

Sean Griffin demonstrated a strong grasp of Appellate Practice law, which was evident in the way he handled my case. His expertise in administrative and public law was particularly helpful in navigating the complexities of my appeal. However, I found the communication to be somewhat inconsistent—there were delays in responses that could have been more timely. While Griffin’s professional background and recognition as a Lawyer of the Year in Montréal suggest a high level of competence, the overall experience felt somewhat impersonal. The results were satisfactory, but I had hoped for more proactive updates on the case progress. Overall, a capable attorney, but there’s room for improvement in client communication and managing expectations.
