Hi @ilanD,
Welcome to the community and thank you for introducing yourself here. 
I am the Community Manager for OpenZeppelin based in Melbourne Australia. 
The OpenZeppelin team is spread around the world.
The guide Test smart contracts like a rockstar is a great overview of all things testing (OpenZeppelin Test Environment is being added to the guide too), though I assume you are aware/using these already.
I know that you are already looking at Blazing Fast Contracts Testing and OpenZeppelin Test Helpers 0.5.
The community forum is great for discussing smart contract and dapp development. I hope you can share some of the things that you are working on and your knowledge with the community.
Thanks again.
