"I can't recommend Mulliken Law highly enough. Erin and Olivia were incredible throughout my case. Olivia diligently worked for eighteen months to build a strong case, and when it went to trial, Erin expertly negotiated a fair settlement after just one day. I felt fully supported by them and Murray during this challenging time. I'm happy with the resolution and confident that my rights have been protected. Thank you, Mulliken Law!"
