Jameson is an advocate, artist, entrepreneur, yoga-meditation practitioner and student. He is founder of FABUM Inc., a nonprofit arts organization, and has helped develop two technology startups.

He has written, produced and directed several theatrical works and has performed in diverse productions and venues in Washington, DC, New York City and Philadelphia. He serves on the Board of Governors of the Arts Club of Washington, where he chairs the organization's Drama and Programs Committees.

Inspired by BP’s oil spill in the Gulf of Mexico, as part of the CETAB (Cleaner Environment Through Accountability in Bankruptcy) advocacy campaign, he lobbied Congress in 2010 to amend the U.S. Bankruptcy Code to prevent corporate environmental clean up costs (such as from the Deepwater Horizon oil spill) being passed on to U.S. tax payers. 

He launched and stewards the Diplomats of Dance Society, which supports the cultural diplomacy of the internationally acclaimed Dana Tai Soon Burgess Dance Company. A classical ballet dancer growing up, Jameson and his husband, choreographer Dana Tai Soon Burgess, established a fund to nurture dance education at the University of New Mexico. 

Jameson offers a free weekly restorative yoga class, as well as other meditation and awareness practice (from nature baths to events with Tibetan singing bowls) in the Washington, DC metro area.

He holds a 300-hour yoga teacher certification from the Swami Krishnananda Yoga Vidyapeeth Ashram outside Mysore, India, and studied under Dr. Ashutosh Agarwal, disciple of Swami Krishnananda Saraswati, as well as under Hatha Yoga teacher and gold medalist Yogacharya Kadambari CP. He is currently enrolled in a two-year Karuna Training certification, a contemplative psychology program under Archaya Melissa Moore, PhD., student of Chögyam Trungpa, Buddhist meditation master and founder of the Vajradhatu and Naropa University, as well as the Shambhala Training Method.
