Totally Random, Totally Wonderful Milwaukee

Milwaukee is the city built on beer and brewing that is also an Old Fashioneds oasis and Bloody Mary metropolis. It is America’s Third Coast with the flying Milwaukee Art Museum on Lake Michigan and the home base of Harley-Davidson. Milwaukee is the community of culinary convergences from traditional fare like cheese curds and bratwurst to cuisine created by James Beard-recognized chefs. The city is the site of the tavern that pedals on the pavement and paddles on the water. All of it is totally random, totally wonderful, and totally Milwaukee.

Diversity and Inclusion

At MCW and within the Department of Pediatrics, we have several programs and resources focused on fostering a diverse and inclusive environment. Our departmental and institutional focus is confronting negative perceptions and welcoming our community. Below is just a sampling of the efforts across our institutions to embed the principles of diversity and inclusion into our culture.

  • DOP Diversity, Equity and Inclusion Council | Our Diversity Council, led by Dr. Mike Levas, the DOP Vice Chair for Diversity and Inclusion, and comprised of faculty, staff, administration, and trainees, is focused on connecting with partners across our system and within the community to ensure the DOP is a diverse, equitable and inclusive employer.
  • DOP Fellowship and Residency Diversity and Inclusion Committees | In a city filled with its own diversity and rich cultural history, our fellows and residents recognize the importance of addressing diversity, health equity, and inclusion within our programs. As such, the program is proud to recognize the presence and work of its Committee for Diversity, Equity, and Inclusion.
  • DOP Unconscious Bias Training | The AAMC has partnered with Cook Ross, Inc., a leading consulting firm, to create training focused on the science behind unconscious bias to help academic medical staff and faculty mitigate disparities. Seven members of our team have earned a certification as unconscious bias trainers through Cook Ross. These trainers have translated what they’ve learned into a two-hour training for our faculty and staff. By learning how to identify and confront unconscious bias, it is possible to mitigate the impact and promote respect for all groups.
  • Trauma-Informed Workplace Training | This committee has undertaken actions including a department-wide survey and the creation of four online training modules sharing the principles of trauma-informed approach and how to recognize signs and symptoms of trauma in ourselves and others. This group started as part of Fostering Futures, a state-wide initiative aimed at infusing a trauma-informed approach into all the systems and organizations that touch the lives of Wisconsin citizens with the goal of expanding across the state to make Wisconsin the first trauma-informed state in the nation.
  • Office of Diversity and Inclusion | Established in March 2016, the MCW Office of Diversity and Inclusion (ODI) partners within MCW and with community partners to foster and drive inclusion excellence as an effective, empowering enabler of MCW mission and strategic goals.
  • Spring Festival of Cultures | The annual Spring Festival of Cultures encourages an increased awareness and celebration of the visible and non-visible identities among our MCW community. This three-day event is an opportunity to promote the fostering of diversity, inclusion and unity at MCW.
  • President’s Diversity and Inclusion Award | MCW’s President's Diversity and Inclusion Award recognizes the accomplishments of faculty, staff, students, residents, trainees, and community members in contributing to diversity and inclusion through exemplary leadership.
  • Institute of Health and Equity | The Institute for Health & Equity is focused on researching the root causes of health disparities in our communities, and advancing the best ideas to foster health equity throughout the world. We target populations with abnormally high rates of disease and injury – urban and rural alike – and then we find out why. Partnering with community health collaborators who live and work closest to the most vulnerable populations, we are making an impact on reducing those disparities, one community at a time.
  • GMF-MCW Partnership | Through their overall partnership, MCW and GMF will bring complementary expertise on a range of strategies to invest in the health, equity and economic well-being of people across Milwaukee, beginning with the neighborhoods adjacent to the new development. Guided by community priorities and data, the GMF-MCW Partnership will be a catalyst for additional investment and community impact. Together, the partners will:
    • Engage resident and community partnerships
    • Improve social determinants of health
    • Catalyze change that leverages resources and investment

I was geographically limited to Chicago due to my husband’s job. I came to MCW because of the proximity to Chicago. I did not expect much as I knew this was a new program and I was the first fellow. I was blown away by the individual attention from everyone. From faculty to staff members including research coordinator, nurses and administration. I was invited to participate in all the procedures like biopsies and acute dialysis. Not only did it offer a fulfilling clinical and educational experience, it was also an incredible research experience. I was equipped with both clinical and basic science research tools. I was very fortunate to have opportunities to learn from mentors in physiology and internal medicine/nephrology.  Graduating from the pediatric nephrology program I was a very confident, well equipped clinician. Milwaukee was also great place to live and start a new family. It offered great food, outdoor activities and we made lifelong friendships.

-Shireen Hashmat, MD

MCW combines excellent clinical training with vast research opportunities. Having a strong CICU, PICU, neonatology and urology program along with diverse patient population gives nephrology fellows the opportunity to see the length and breadth of the renal disease spectrum. MCW also has a strong liver and renal transplant program and fellows are involved in every stage of decision making and care of their patients. Along with multidisciplinary didactics and conferences, fellows are given the opportunity to choose their own research mentors and projects. There is a good mix of both basic, clinical and translational science research to choose from. Besides, Milwaukee is a great family friendly city. From food to arts, music to sports, there is something here for everyone!
