Live since August 9, 2026 Mosaic

Shape where you belong.

We're a collective of Jewish young adults in San Diego, ages 25 to 40. Shabbat dinners, hikes and beach days, pickleball, game nights, holiday gatherings, and talks that actually go somewhere. You find all of it, and each other, in one app on your phone.

How It Works

Mosaic lives on your phone's home screen, not in the app store. Three steps and you're in.

  1. Open mosaicsandiego.org

    On your phone, go to mosaicsandiego.org and become a member.

  2. Add it to your home screen

    On iPhone, tap Share in Safari, then Add to Home Screen. On Android, open the Chrome menu and tap Add to Home screen. From then on it opens like any other app.

  3. Find a gathering

    The app has four tabs: Home, Gatherings, Community and Me. Open Gatherings, pick what fits your week, and RSVP.

The Kinds of Gatherings We Have

Some are around a table, some are outside, some go deeper, and some are just for fun. Members host plenty of them too.

Built by Us

Mosaic is only as good as what we bring to it. If you have an idea for a gathering, you can host it. If something could work better, say so. Both go straight to Shoshana Rice, who leads Mosaic.

Host a gathering

Tell Shoshana what you have in mind, who it's for, and roughly when. We'll work out the rest together.

Email Shoshana

Give feedback

A gathering you loved, one that fell flat, or something you wish the app did. Write it down and send it over.
