Dr. Samantha Tolliver Becomes the First Black Woman to Serve as D.C.’s Chief Toxicologist, Championing Hard Work, Mentorship, and Representation in STEM

Breaking Barriers in Forensic Science

Dr. Samantha Tolliver just made history as Washington D.C.’s first Black woman chief toxicologist. Leading the Office of the Chief Medical Examiner’s toxicology division, she oversees a team that processed 2,300 cases last year. These included sexual assault evidence, DUIs, and post-mortem examinations.

The West Virginia native never imagined this career path early on. “My high school chemistry teacher told me I’m not a chemist,” Tolliver recalled. She started as a lab dishwasher in Miami before earning three chemistry degrees while working her way up. Now she manages D.C.’s breath alcohol program and trains law enforcement officers.

Her journey proves perseverance pays off. “Work hard, stay focused and get rid of the noise,” Tolliver advises. “Just stay focused on what your goal is, and keep moving forward.”

Building a Legacy of Mentorship and Representation

Tolliver’s office reflects her commitment to empowering women in STEM. Thirteen of her seventeen staff members are women, creating what she calls a “female-dominated” powerhouse team. “I’ll put my staff up against anyone else,” she proudly states.

She draws inspiration from pioneers like astronaut Dr. Mae Jemison. “She was this light for me that said you can do whatever you’re dreaming of,” Tolliver explained. Now she pays it forward by mentoring others. “When you reach some point, you reach back,” she emphasizes.

The toxicology field actually leads in gender equality compared to other STEM areas. “We’re about 50/50 male versus female,” Tolliver notes. She believes this supportive environment helps women thrive in forensic science careers.

Championing the Next Generation of Scientists

For young women considering STEM, Tolliver’s message is clear: “Take up the space.” She encourages persistence despite doubts or setbacks. Her own story proves that determination can overcome early discouragement.

Tolliver sees mentorship as key to building diversity in science. “Seek guidance from whoever is willing to give it,” she advises. “The future is what we make it.” She hopes to inspire others to dream “as bright as the star you see.”

As D.C.’s top toxicologist, Tolliver isn’t just analyzing evidence – she’s creating pathways for more women and minorities to succeed in forensic science. Her leadership shows how representation transforms workplaces and communities.
