Billi Jo Hart was my student at Meramec STLCC in the Interior Design program in the spring of 2023. The course concentrated on Commercial Interior Design (ART 251). I can firmly recommend Billi Jo for any Interior Design position. Billi Jo's work highlights a rare combination of creativity, detail, and originality. Her work reflects a high level of research, combined with the heart to make a design truly sing. I am looking forward to seeing the positive contributions Billi Jo makes to the design community of St. Louis.

Billi Jo Hart is such a pleasure to work with and is extremely talented. She is very professional, has an eye for the best possible shots, and her lighting techniques are great. I felt more comfortable working with her than most of the photographers that I have worked with. Her work ethic and drive to capture the best possible shot are very admirable. I would highly recommend any of her various photography services to anyone. I’m looking forward to working with her again.

I turned to Billi Jo Hart Photography because I wanted gorgeous pictures done of me. As a plus size woman it is very hard for me to be the focus in a picture. Let’s not even mention being half naked in the picture as a plus size woman. I chose Billi Jo Hart Photography because her previous work showed me she knew how to create gorgeous pictures of plus women. When she sent me my sneak peek today, I sat in my car and cried for 30 mins because for the first time I had photographic proof I wasn’t just the cute big girl or pretty plus size girl but that I was gorgeous and even sexy.

For over thirty years, I have studied with all kinds of yoga teachers, including some with a great deal of training and experience, but I have seen few who are as gifted at teaching yoga as Billi Jo is. I have been attending her classes for the last several months on a regular basis, and I have found her to be consistently calm and steady in her demeanor and very skilled in her cueing...

Billi Jo is my yoga instructor at another facility in Champaign. She is an outstanding teacher! Her verbal delivery is clear and smooth. Her explanation and modeling of the poses is quite helpful, as well as the recommended accomodations she suggests for the variety of yoga levels in our class. I highly recommend her as a yoga instructor for persons of all ability levels. I know I look forward to seeing her each week for my yoga workout!

Did a 3 hour yoga photoshoot with her and got about 20 of the best photos I've ever been in. Absolutely stunning work, photography and the work she did on the pictures afterword. 10 stars.
