“This is just the beginning. I highly recommend Margali and Flynn Designs. It has been a pleasure to work with everyone on the team especially Keri Flynn, who is a very talented designer. Keri pays great attention to detail and is always responsive, flexible and extremely helpful in the decision-making process.”
- Manhasset 1 - Decorating
“Keri has designed both my home and my daughter’s, and I can’t recommend her enough. She is one of the most professional, committed, and hardworking individuals I have ever met. Keri is proficient in all design genres and doesn’t rest until the job is complete. Her dedicated team complements her work beautifully. I highly recommend enlisting her early in the process, even before finalizing with an architect. Keri is a true find, and I would hire her for any design project.”
