We’re constantly bombarded with the next wellness craze, superfood, quick-fix, detox, and diet…it’s exhausting! Yet, the Hamptons is the ultimate ‘play ground’ for indulgence. How are we supposed to stay healthy and feel balanced while taking advantage of all that the Hamptons has to offer? Not only is it possible to reach this balance, it can actually be enjoyable too.

I’m Kiley, founder of One Healthy Hamptons and Nutritious Life Certified Nutritionist. After attaining a Master’s Degree in Clinical Social Work from Boston College and moving to the Hamptons ten years ago, I learned that I love to help people to live healthier and happier,  In addition to loving all things health and Hamptons, I’m on a mission to help you thrive.


After years of education, experimentation, and self-discovery, I discovered how health and happiness can coincide, in balance, without deprivation, rules, labels, or negativity and I’m here to empower you to do the same, because you deserve it!

My hands-on approach integrates all facets of the mind and body, starting fresh with each client. There’s no one size fits all plan, no black-and-white/good-or-bad, or counting calories. It’s about eating abundantly, feeling in control, practicing mindfulness, and happily indulging in life.

Together, we’ll set goals to fit your lifestyle, make manageable changes, taste the healthy goodness, and find your healthiest, happiest life. Email to set up your consultation today. The best is yet to come, let’s get there together.
