4x founder. Relentless experimenter. Father.

I’ve spent the last 15 years building businesses and testing every health protocol I can find. I’m here to share the raw lessons from the trenches.

(No, the sauna isn't on for the little guy... he’s just here for the board meeting)

The slowest decisions I've ever made were also the worst ones; the needle-moving, life-changing decisions came from fast gut decisions. Gut decisions aren't random; they're a product of all your experience compressed into a feeling. The longer you sit on a decision, the more you replace that signal with noise from other people's opinions. So, the best decisions of your life will probably feel too fast... that's the point.

Most entrepreneurs work on 14 things. The great ones work on 3. I am admittedly working on this; busy is what happens when you're bad at saying no. I think the most important productivity decision you'll make today isn't your task list, it is your project list.

8. Akari (Williamsburg): Akari is an ode to Japanese sentōs and onsens, built as a membership model so you can use the sauna and cold plunge as many times as you want for a flat fee. Warm, intimate space that leads to a back garden. Recently updated with a larger plunge pool and a quiet seating area, making it a genuine escape from the city.

7. SAA (Williamsburg): A members' co-working club that put the spa on the top floor. Panoramic skyline views. Former warehouse turned into a recovery space with dramatic green marble to line the sauna, steam room, hammam, cold plunge pool, and warm bathing pool. There's also a set of smaller wood-lined sauna pods positioned on the roof.
