Nicky Dunlap, Social Media and Photography Coordinator

Nicky is passionate about bringing yoga into the lives of others and using creative ways to do so. She uses her bachelor’s degree in psychology to better understand the people around her, and she has fun thinking about how people tick and using that insight to come up with methods of engaging different types of people. With a masters degree in library and information science, she has a knack for research and digging deeper to discover new things and create new ideas. Combined with her love of writing, photography and organization, all of these skills and passions have been fused together into one when she began working for Green Heiress, promoting the studio and creating fun, inspiring ways to bring more and more people into the space to discover yoga, healing and, ultimately, themselves.


Marta Fox, Executive Assistant

Marta first became interested in yoga 20 years ago while living in Omaha, NE. The regular practice of yoga helped her both physically and mentally. In fact, she benefited from the practice so much that she decided to go through yoga teacher training in order to be able to share the love with her community. Marta completed East/West yoga teacher training in 2004 under the mentorship of Tippy Denenberg and Theresa Murphy. Marta taught yoga at One Tree Yoga in Omaha for several years before moving with her family to the Fox Chapel Area in 2008. After spending some time raising her two boys and doing community and volunteer work, Marta decided that she really wanted to go back to her yoga teaching roots. Marta is a big believer in the old Buddhist philosophy, “When the student is ready, the teacher will appear” and feels that this chance to teach yoga in this community is also an opportunity to her learn and grow with her students. Namaste!
