Experienced but delays in response

I worked with Hélène Deschamps Marquis on a data privacy compliance matter, and I was impressed by her deep knowledge of Information Technology Law. Her expertise was evident in how she navigated the complexities of our case, particularly around GDPR compliance and data security protocols. However, I did find that communication could be sporadic at times, and there were longer-than-expected wait times between responses. While I had no doubts about her competence, especially given her recognition in Privacy and Data Security Law, the lack of timely updates made the process a bit more stressful than necessary. Overall, she delivered solid legal guidance, but I hope future interactions see improved responsiveness.
