Experience

Tammera R. Diehm is a shareholder at Winthrop & Weinstine with extensive expertise in complex real estate and leasing matters. In her practice, Tami has represented local and national clients of all types and sizes in real estate transactions involving multiple levels of government approvals, environmental challenges and various forms of public and private financing. Tami regularly appears before local governments and regulatory agencies on behalf of clients seeking land use and permitting approvals, and works with clients to find creative solutions to complex projects.  Tami served as city attorney for a first ring suburb for eight years, and is currently serving her third term as an elected city council member for Columbia Heights, which is where she lives.  Her knowledge of both the legal and political aspects of land use and zoning issues bring a fresh perspective to real estate development projects.  

In addition to land use, environmental and real estate development, Tami has experience representing both for-profit and tax-exempt organizations on a variety of issues including formation, tax and general governance. She has assisted organizations with compliance matters involving the Internal Revenue Service, the Minnesota Attorney General’s office, the Minnesota Campaign Finance and Public Disclosure Board and the Federal Election Commission. Tami provides general counsel services to a number of for-profit and non-profit clients of varying sizes throughout the Twin Cities area, and is a frequent speaker on issues related to lobbying and corporate political involvement.    

Prior to joining the firm, Tami served as a judicial extern for Federal Magistrate Judge Jonathan Lebedoff (2003) and clerked for the Honorable Russell A. Anderson, Minnesota Supreme Court, 2003-2004. Tami lives in Columbia Heights where she is an elected member of the City Council as well as a member of the Economic Development Authority and the Chair of the Housing and Redevelopment Authority. Tami is an appointed member of the Metropolitan Council’s Land Use Advisory Committee and served as a policy member of the Minneapolis Nicollet-Central Policy Advisory Committee. Tami has been recognized by her peers with honors including Rising Star, 2007-2012; inclusion in The Best Lawyers in America® in the areas of Municipal Law and Land Use Zoning, 2010-2014; a Forty Under Forty honoree and the MSBA North Star Lawyer recognition (2013-2014).
