Our Mission

PSR Wisconsin is an organization of health professionals and other concerned individuals who work to protect human life from the gravest threats to health and survival.

By educating ourselves and the public about these threats, we hope to prevent what we cannot cure.

About Us

PSR Wisconsin recognizes that the two biggest threats today to human survival are nuclear weapons and climate change. Our members are also deeply concerned about the health consequences of the growing contamination of our environment by toxic chemicals and radioactive isotopes. 

We rely on the medical and public health expertise of our members to prevent nuclear war, to reverse our climate change trajectory and to stop further degradation of our  environment.

  1. We call upon on our elected officials to support the United Nations Treaty on the Prohibition of Nuclear Weapons (TPNW) which calls for multilateral, verifiable nuclear disarmament.

  2. We call upon our leaders to institute immediate measures to curb greenhouse gas emissions and invest in renewable energy technologies.

  3. We call upon our leaders to act immediately to cleanup chemical and radioactive waste sites around the US, and to prevent future release into our air, water and earth of harmful toxins.

The work of PSR Wisconsin is guided by a steering committee. The committee usually meets the third Sunday of each month. The members of the steering committee are:

  • Bruce Barrett, MD, PhD;

  • Bob Block, MD;

  • Ann Behrmann, MD;

  • Mary Dougherty;

  • Claire Gervais, MD;

  • Rebecca Patterson;

  • Karin Ringler, PhD;

  • Paula Rogge, MD;

  • Amy Schulz, RN (President);

  • Melissa Stiles, MD;

  • Monica Vohmann, MD.

The committee generally meets on the third Sunday of each month.  Contact the PSR Wisconsin office if you are interested in joining the steering committee or volunteering for one of our programs, tel. 608/232-9945, Hannah Fisher, Administrative Coordinator.

PSR Wisconsin is a 501(c)3 organization and registered as a charitable organization with the State of Wisconsin.  We rely on the generosity of our members and donors to fund our work.

Our PSR Wisconsin Chapter was created in 1983 in response to the threat of nuclear annihilation.  In 1979, the Soviet Union deployed missiles in Eastern Europe and NATO prepared to deploy new Cruise and Pershing II missiles in Western Europe.  Millions of people across Europe and the U.S. took to the streets in massive protest marches to end the accelerating nuclear arms race.  The nuclear freeze movement in the U.S. led to states, cities, and towns across the country passing referenda demanding a halt to U.S. and Soviet nuclear-weapons development.

PSR WI gave countless public talks about the disastrous consequences of a single nuclear bomb being dropped on Madison or Milwaukee.  We also tried to increase trust and cooperation between the US and Russia by sponsoring exchanges between doctors from both countries. National PSR was instrumental in educating President Reagan about the consequences of using nuclear weapons.   In 1985, Russian President Mikhail Gorbachev and US President Ronald Reagan met in Reykjavik, Iceland and agreed on a “Zero Option” to eliminate all intermediate range nuclear weapons on both sides.  This is the INF Treaty that our current administration proposes to abandon.

President Trump also decided on May 8, 2018 to pull out of the Iran Nuclear Deal.  This accord between Iran and 7 other nations was one of the most successful efforts to prevent the spread of nuclear weapons. Intelligence and non-proliferation agencies are agreed that Iran is in full compliance.   The remaining 6 nations and Iran continue to honor the accord.  Trump’s withdrawal from the deal weakens international efforts towards disarmament.  Every failure of nuclear diplomacy increases the danger of war.

The role PSR played in the 1980’s was critical to the nuclear disarmament that took place over the last 3 decades. The immediate goal of our efforts is to exert pressure on the government to honor the INF Treaty and the Iran Nuclear Deal.  Our long-term goals are complete nuclear disarmament, an end to runaway climate change, and cleansing our world of environmental toxins.
