Admitted to the Virginia bar, by 1830 Camden partnered with
John J. Allen, a lawyer who became a U.S. congressman and later a Virginia judge (of the 17th Circuit; and for 25 years of Virginia's
Court of Appeals including through the American Civil War). Camden invested heavily in real estate, as well as worked to develop roads, railroads and energy resources in western Virginia, including as President of the
Northwestern Turnpike. Meanwhile, in 1828 Camden won his first political office, elected as a
Whig as one of Lewis County's delegates in the Virginia House of Delegates and serving alongside Thomas Bland. His brother John S. Camden would also later win election for a term in the House of Delegates for a term (1845-1846). Meanwhile, Gideon Camden developed a legal practice extending (as did his personal investments) between several mountain counties. He became Commonwealth Attorney for Randolph County in 1837. Gideon Camden later won election as a delegate to the
Virginia Constitutional Convention of 1850, representing Doddridge, Wetzel, Harrison, Tyler, Wood and Ritchie counties alongside fellow lawyers and investors

John F. Snodgrass and
Peter G. Van Winkle. From 1843 to 1852,
Jonathan M. Bennett became Gideon Camden's law partner as well as a part-time legislator. Legislators elected Gideon Camden as judge of Virginia's 21st circuit in May 1852, and re-elected him to another 8-year term in 1860. During the 1850s, a grand jury under the guidance of Judge Hall and prosecutor Benjamin Wilson indicted
Horace Greeley of New York for violating Virginia's prohibition against distribution of incendiary newspapers, in addition to his two subscribers in the county, William P. Hall and Ira Hart, but the case never came to trial. In the 1850 federal census, Camden owned 7 enslaved people in Harrison county: black men aged 35 and 20, black boys aged 12 and 8 years old, and a 35 year old black woman and girls aged 14 and 3 years old. All told, Harrison County that year had 346 "bondsmen": 161 male and 185 females. In the 1860 federal census, Camden owned two black men, aged 45 and 26 in Harrison County.
