Goertzen was born on June 12, 1969^[5] in Winnipeg, Manitoba^{[citation needed]} but was raised in Steinbach, Manitoba. He attended public school in Steinbach and graduated high school from the Steinbach Regional Secondary School in June 1987. Goertzen obtained a Bachelor of Arts, majoring in Economics, a Bachelor of Commerce and a Bachelor of Law each from the University of Manitoba. While attending Robson Hall law school at the University of Manitoba, Goertzen was awarded more than a dozen academic prizes and was the school's top student during his second year of law studies.^{[citation needed]}

Goertzen served for two years as the Vice-President of the Steinbach Arts Council and served as Vice-President of the Southeast Helping Hands Food Bank in Steinbach for seven years. He has been involved as a participant and fundraiser in a number of community related causes including the Mennonite Heritage Village Museum and the Steinbach Association for Community Living. He is a member of the South East Rotary Club.

In June 2007, Goertzen was awarded the "HOPE" medal by the Lions Club Foundation of Manitoba and Northwestern Ontario for his community service work helping those less fortunate in Manitoba ^{[citation needed]}. In 2012 he was awarded the Queen Elizabeth II Diamond Jubilee Medal in recognition of community service by Governor General of Canada David Johnson.

Goertzen became involved in political activities while attending high school, serving as an early organizer for the Reform Party of Canada. In 1995, Goertzen was hired as an intern at the Manitoba Legislature serving with the Progressive Conservative Caucus. Following the internship, he served in the Manitoba Department of Culture, Heritage and Citizenship and subsequently worked as an Executive Assistant to MLAs Jim Penner and Albert Driedger. Following the 2000 federal election, Goertzen also worked as an advisor to Provencher Member of Parliament Vic Toews and was a key local organizer for Toews in the 2000, 2004 and 2006 federal elections. In 2003, he participated in a public protest against the legalization of same-sex marriage in Canada.

Prior to seeking elected office himself, Goertzen also served as the President of the Steinbach Progressive Conservative Association, as a Regional Director on the Board of the Manitoba Progressive Conservative Party and as a member of the Management Committee of the Manitoba Progressive Conservative Party.

One week prior to the calling of the 2003 provincial election, Steinbach MLA Jim Penner announced he had been diagnosed with pancreatic cancer and would not be seeking re-election.^[6] After the election was called a short nomination process occurred. Some critics suggested Goertzen's service as local association President gave him an advantage in the short nomination time frame. The sudden events had no impact on the election result, however. Steinbach is one of the Manitoba PCs' safest seats, and Goertzen was elected with over 74% of the popular vote despite the poor showing of PC candidates elsewhere in the province. Goertzen became the youngest MLA ever elected from Steinbach since its creation in 1990, as well as the first Manitoba Legislative Intern to be elected to the Manitoba Legislature.

After his election to the Manitoba Legislature, Goertzen was promoted to the shadow cabinet as Chief Justice Critic and in 2005 was also appointed Deputy House Leader. As Justice Critic, Goertzen called for increased police resources, stronger laws against organized crime, electronic monitoring of sex offenders and a drug treatment court to assist individuals addicted to drugs and alcohol. In 2005-2006, Goertzen held a series of informational meetings across Manitoba about Crystal Meth and lobbied for new legislation to allow parents of drug addicted teenagers to place their children in drug treatment. The NDP government accepted that suggestion and legislation was passed June 13, 2006.

Goertzen was a strong supporter of Opposition Leader Stuart Murray and refused to participate in internal Caucus dissent that ultimately led to the end of Murray's leadership in November 2005.

Goertzen was among the first MLAs to endorse the provincial PC leadership campaign of Hugh McFadyen who eventually won the leadership. McFadyen reappointed Goertzen as Justice Critic after his leadership election and also appointed him the PC House Leader. Goertzen was again nominated the provincial PC candidate for Steinbach on September 8, 2006. On May 22, 2007 Goertzen was re-elected with 83% of the vote, the largest victory in the history of the riding.

In February 2010, Goertzen was named Deputy Leader of the Progressive Conservative Party of Manitoba, and hence Deputy Leader of the Opposition. On October 4, 2011, Goertzen was re-elected in Steinbach by another large majority, although the PC's once again lost the election to the NDP. With the resignation of McFayden as party leader after the election, there was some speculation in the local media that Goertzen may be a candidate for the position.

Following the 2011 election and selection of Brian Pallister as leader of the Manitoba Progressive Conservative Party, Goertzen was again appointed House Leader and Justice Critic for the PC Caucus. In 2013 he led a filibuster in the Manitoba Legislature to protest the increase of the provincial sales tax (PST) by the NDP government.

In 2013, despite widespread media speculation, he declined to run for the Conservative Party of Canada in the federal riding of Provencher, centered on Steinbach, following the resignation of MP Vic Toews.

Following the Progressive Conservative victory in the 2016 provincial election, newly-elected premier Pallister named Goertzen as a member of the new cabinet, assigning him the office of Health, Seniors and Active Living.^[7]

In May 2018, Goertzen was strongly criticized for speaking at an anti-abortion rally in Steinbach, and for constant deferral of questions related to women's reproductive matters, including abortion, to Rochelle Squires, minister of the status of women.^[8]

In September 2020, Goertzen made a Facebook post emphasizing the right to refuse vaccination, which received widespread condemnation by the public and which many medical experts considered to be problematic coming from an education minister and previous health minister.^[9]

Goertzen married his wife Kimberley Hiebert in 1997. They live in Steinbach, Manitoba and have one son.^[5]

Goertzen has published several articles related to law and politics including in the Asper Review of International Business and Trade Law (Volume 3- 2003) and Underneath the Golden Boy (Volume 3-2004). In November 2006, he published a book on the life of Jim Penner, his predecessor in the Legislature, entitled A Life Well Lived: The Story of Jim Penner and Penner Foods (National Library of Canada ISBN 0-9781405-0-8).
