Uh, I had to do some thinking there. My brain isn't exactly working along haha. 
If I make her 30, they couldn't have met in 2005. Because she would be too young. 
Unless they met when she wasn't in uniform yet. 

From what I read, police training in the UK takes 2 years. In 2005 she'd be 16. She would start police training 2 years later. 
What if... - and I'm just thinking out loud - Ransom inspired her to join the police force/start the academy? Because she had a bit of a rebellious youth. Would make sense if she's a Klaustreich or Yaguaraté. They would have to meet somewhere in 2005/6?

OK, so they met in 2005. HE would have been in police training at that time. Which is fine. Maybe she worked in a diner? or restaurant. He struck up a conversation with her and she admitted she was thinking about being a Po-Po too. So he gave her advice on how to get in. She may have joined right after graduating secondary school, which would put her in uniform at age 20 and they could have worked together for one year (2009 - 2010). The kicker is, it would be another year, after he left uniformed duty that his abilities as a Grimm materialized. So she didn't know he was a Grimm and he didn't know she was a Klaustreich.

By the time our story begins, maybe they had worked on a case together in Winchester? He came out to give her a hand or maybe they don't work again until our story begins? Then the surprise for both of them at this next encounter is of their Wesen identities. This could actually work out well for us if they don't know before this story begins. :)
