Since being invested with Celebrity status from her win, Machamer has been invited to a number of culinary events. She and the 2007 Hell's Kitchen winner Rock Harper competed in a cookoff and both will be among those presenting at the 2009 Scottsdale Culinary Festival in Arizona. After Gordon Ramsay at The London West Hollywood was sold back to LXR hotels, Machamer traveled to Napa to study wine at CIA Greystone in St. Helena, California. Shortly after, she returned to Los Angeles as part of the opening team at Bouchon in Beverly Hills for celebrated chef, Thomas Keller.

Machamer, the daughter of Rick and Leasa Machamer, was born and raised in St. Louis, and began working in restaurants at age 16. She graduated from Lafayette High School in 2000 and after some time in college, she dropped out of pre-law and decided that cooking was her calling in life. After an apprenticeship with chef Larry Forgione at An American Place, she began her formal training at Forest Park Community College in 2003. She moved on to The Culinary Institute of America in Hyde Park, in the spring of 2006 and graduated on February 29, 2008.

In January 2009, she was featured as a host at the St. Louis Food & Wine Experience.

In 2011, she relocated to the Napa Valley, where she has found a new niche bridging the gap between food and wine at the much celebrated B Cellars, in Calistoga, California.

She also appeared in the 11th season of Hell's Kitchen (in 2013) as part of a brigade consisting of past Hell's Kitchen winners in order to compete against the final 5 contestants.

Machamer briefly appeared in the 16th-season premiere (in 2016) as a guest with Season 12 winner Scott Commings during the red team's challenge reward (dinner with Ramsay). She gave the women several tips about working under pressure in Hell's Kitchen.
