Title IX case against UCLA, client confidential

It was such a weight off our shoulders; suddenly somebody else with a lot more experience was managing the case.

Sandeep Mander, Mander v. Royal Borough of Windsor & Maidenhead

We really thought that there was nothing that anybody could do for us. We were wrong.

Dr Celeste Kidd, Aslin et al v. University of Rochester et al

To get the result you got you must be as tough with your legal opposites as you are kind and understanding to your clients.

AOA client, confidential

Compared with other law firms I’ve worked with, no one matches the combination that McO has of experience, brilliance, ferocious fighting and deep empathy for their clients.

Dr Holly Atkinson, Atkinson et al v. Mount Sinai Health System, Inc. et al

Because my case could not bear public scrutiny, a very powerful institution used massive financial resources to try to crush me for asking for my disability rights. This was a huge mistake, as they didn’t know that I would obtain McO representation. I couldn’t ask for better representation.
