I would love to know if this was a custom made table too! Any info would be appreciated.

Check out IKEA they have work tables.

This is custom made - tho Pottery Barn and Ballard Designs have components that can be used as such, they probably won't be any less expensive.

How do you get a custom made table? Who do you contact?

Hire an architect or designer to design it for you, then have a cabinetshop or woodworker build it

Yes, it's a custom design I did for the client.

Love this clean simple white look. I am designing my sewing studio and am interested in the taller open shelving against the wall ?
Are the shelves adjustable ? Did you custom design these ? ~Thanks for your time.

The owner bought those from a home organizer store called "More Space Place" here in Austin.
