Sarah Kellner



Sarah Kellner advocates for clients to achieve favorable outcomes for their real estate projects and disputes. She focuses on complex real estate advocacy, including land use, real property tax appeals, landlord-tenant litigation, and condemnation, bringing her significant litigation experience to the table to help her clients achieve favorable results in their real estate matters.

Eminent Domain

In her eminent domain work, Sarah counsels both condemnor and landowner clients. For condemnors, she oversees projects and negotiations from inception (including during the planning and engineering phases) through acquisition. She also represents developer and individual landowners, utility and energy companies, companies with nationwide property portfolios, and retail centers in challenging eminent domain actions and achieving maximum just compensation awards.

Property Tax Appeals

Sarah also helps companies challenge their real property tax assessments and valuations. With significant valuation experience, she advocates for her clients at all levels of the tax appeal process, including proceedings before the Colorado Board of Assessment Appeals (BAA) and through the abatement process.

Land Use

In her land use work, Sarah assists clients through development hurdles and works with municipalities and other government entities to get favorable project results for her clients. She works with landowners through the approval process when roadblocks arise, helping position them for potential litigation if their land use approvals are denied. Her advocacy on behalf of her clients includes work at both the local level as well as in court proceedings, including Rule 106 and declaratory judgment actions.
