Mr. Grutman discussed collecting at the couple’s home, a Miami Beach bi-level where they live with their two children, Kaia, 2, and Vida, 9 months, as well as two dogs and two cats.

These are edited excerpts from the conversation.

When did your love of art start?

Art has appealed to me for a long time because I’m a creative guy, but Miami’s Wynwood Arts District inspired me to start buying my own works. I was going there more than 10 years ago before there was much development in the neighborhood and thought the arts movement happening there was really cool. It made me want to a build a collection I loved.

I became so obsessed with Wynwood that I proposed to Isabela there, and we got married inside Wynwood Walls [an outdoor gallery featuring international graffiti artists].

Where do you find your art?

Luckily, I live in Miami where Art Basel happens and discover tons of artists there who I have become friendly with. Many of them come over when they’re in town for the fair.
