Tiffany Holtz Real Estate

Tiffany Holtz Real Estate Group is a real estate team in Appleton that works with buyers and sellers, offering exclusive buyer agency, traditional listings on the open market, and an automated home valuation tool for homeowners who are not yet ready to sell. Tiffany Holtz leads the team, and Ryan Diedrich serves as director of operations. The team reports more than $240 million in sales in 2025.

Support staff can help with questions before a client is connected with an agent, and the team asks people to call rather than wait on the online form. The team says it serves clients across a wide region from Crivitz in the north to Fond du Lac in the south. The office is at 2830 E John St in Appleton.
