Tamsin Carty

All about the girl... I believe in the power of connection. I do not like working on my own. I excel when I have other people challenge and push me to a level sometimes unknown to myself. There is something magical about building a team. Recruiting the smartest people and creating something that serves the greater purpose, not only for the Nucleus brand, but for the good of our clients alike.

One cannot replace physical human energy with online engagements exclusively, no matter how advanced and innovative we become. The key enabler and driving force in growing one's business, for me, is in connected communication. There is something special about sitting face to face with your client in a room, understanding and conquering challenges through the exemplary brilliance of people united on common goal. That's what differentiates us at Nucleus Optimized Retail Solutions. The ability to engage, listen, align, and execute. We think ahead and collaborate with clients and suppliers, knowing that the decisions we make, have benefit to business.

Fun fact - I love gardening!

Gardening demands time and patience and has taught me that both these qualities are instrumental in the workplace. Instead of getting flustered when you encounter a challenge, you are composed, and resolute in one's ability to resolve
