Meet Cristina, The Person Behind AVA
Senior Executive Assistant and Virtual Chief of Staff services built for leaders who value discretion, trust, and consistent execution.

Cristina Riddell
Founder
I know what it takes to support people at the top. For over a decade, I've worked directly with C-suite leaders, senior investment managers, and high-net-worth individuals across financial services, asset management, and professional services. I've managed the diaries, the inbox, the international travel, the board-level events, the vendor contracts, and the moments where everything needs to happen at once and none of it can go wrong.
I founded Astute Virtual Assistant because I saw a gap: executives and founders who needed senior-level support, not a generalist admin. People who needed someone who understood their world, took full ownership, and could be trusted completely. That's what AVA was built to deliver.
My background in accounting means I'm comfortable in finance-adjacent environments, from compliance paperwork to working closely with finance teams. I'm also bilingual in English and Spanish, which has been invaluable for clients with international operations or Spanish-speaking markets. I hold an IOSH health & safety qualification and Company Secretary certification, which adds another layer of usefulness for clients in regulated or multi-stakeholder environments.
As AVA has grown, so has the team behind it. I've built a curated network of vetted associate professionals, each selected for their expertise, discretion, and the standard of work they deliver. This means I can match each client not just with support, but with the right support. You always deal with me. I ensure the quality.
If you're a CEO, founder, coach, consultant, or HNWI who needs a right hand you can actually trust, I'd love to talk. Let's find out if we're a good fit.
