Biographical Note
Gretchen Wilhelmina Merkle was born in Washington, DC, in 1957. She attended Parkdale Senior High School in Riverdale, Maryland. Afterwards, Merkle began her National Park Service (NPS) career in 1976 as a clerk-typist for the National Mall Operations in the National Capital Region (NCP) during the Bicentennial celebrations in Washington, DC. She occasionally filled in as an interpretive park technician at the Washington Monument, transferring to that job full-time in 1978. The next year she was hired as a fiscal clerk in the United States Park Police (USPP). In 1980 she was qualified as a police officer and subsequently attended the Federal Law Enforcement Training Center (FLETC) in Brunswick, Georgia.After her training, Merkle became a USPP patrol officer in the Washington, DC, Metropolitan Area. She worked in a variety of assignments, ranging from undercover to foot patrol. At the same time, she was also trained in composite drawing, art utilized to identify suspects in police investigations. She graduated from a horse mounted training class in 1985, becoming only the fourth woman horse mounted officer in the USPP. She was stationed at Fort Dupont barn and stayed in this position for about three years.
In 1988 Merkle was promoted to sergeant and worked as a supervisor at Rock Creek Park (ROCR) in Washington, DC. The next year she became a detective sergeant for the Criminal Investigations Branch (CIB) and was instrumental in the creation of the USPP Asset Forfeiture Unit which specialized in identifying, investigating, and seizing property acquired or used by criminals to deter illegal activity. In 1991 Merkle was promoted to lieutenant and served as field commander in Washington, DC, as well as commander of communications. In 1993 she became the first USPP officer to attend the Federal Bureau of Investigation (FBI) National Academy.
Next, Captain Merkle took an assignment as assistant commander of the NPS San Francisco Field Office (SFFO) to establish the law enforcement force for the Presidio property which had become part of the Golden Gate National Recreation Area (GOGA). While working, she attended college and graduated with honors from the University of San Francisco with a Bachelor of Arts in Public Administration. During her time at SFFO Merkle served as assistant commander, operation commander, and administrative commander. In those roles, she was integral to the creation of a new identification technician unit, K-9 unit, and a SWAT team. In 1998 she became the commander of the SFFO and the first USPP woman to achieve the rank of major.
Merkle and four other women filed a complaint with the Equal Employment Opportunity Commission (EEOC) against the USPP for gender discrimination in 1999, which they won in 2002. Merkle was promoted to a deputy chief position. She was then ordered back to Washington, DC, to serve as commander for the Personnel and Training Division. She declined the move and instead retired on November 30, 2002.
