Sienna Winter

Legal Assistant

About me

I joined Oliver & Co as a Legal Assistant in September 2025, after finishing my A-levels. Where I particularly enjoyed studying law, which sparked my interest in pursuing a legal career.

Outside of work and studies, I love baking and spending time with friends and family. I’m a motivated and enthusiastic individual with a passion for netball both on and off the court, and like passing this on through coaching. I enjoy staying active, being part of a team, and continuously learning – qualities that I bring into everything I do.

WHAT OUR

clients say

I chose Oliver & Co because of the service they provided when first making contact with them. I had the option of using a different solicitor via an insurance scheme but I’m so glad I didn’t. I did wonder if their outstanding level of service would drop after I’d committed to them but it didn’t.

Allison Pepper and her assistant, Rebecca Kilfoyle were outstanding at every juncture. No phone calls were missed, no letters delayed or conferences postponed. They really do set the working standard that every company should aspire to. I wouldn’t hesitate to recommend them and will certainly be going back to them should I need any sort of legal service in the future.

Simply outstanding.

My solicitor Allison and her assistant, Rebecca have kept me informed every step of the way and made me feel like I have full control of what happens with my claim. They advise well and ensure all sides are happy, they work none stop to give you the best outcome possible.


The motto ‘work with us and we’ll work with you’ is perfect for this company. If you give the correct information and everyone communicates on the same level with each other it helps get the work done! I can’t thank the both of you enough!
