Theresa is one of the most authentic and creative yoga teachers I have encountered.  Her classes are always interesting, creative, and fun.  Theresa makes her classes very accessible by suggesting and demonstrating modifications.  Her careful cuing of poses makes me feel safe in all of her classes.  During her classes, she offers kernels of wisdom, many of which have impacted my life in a very positive way.  Cathy Smuk
Mama T was my introduction to yoga, and the space she cultivated was my home. I went to one of her classes at a time that I was feeling lost, and immediately felt safe and infatuated with yoga. Her classes are inspiring and her energy is contagious. She makes you feel seen, held and empowered. In her classes I was able to leave my ego at the door and fully embrace being present in my body. Her cues are beyond accurate and her flows are delicious. She’s such an amazing guide in this practice.! - Laura McKenzie 
Theresa, I wanted to take this opportunity to tell you how much you have changed my life. A friend brought me to my first class at Yoga Source many years ago and I immediately felt a connection to the wonderful space you created, a space that I’ve grown to love and always feel welcome and safe in. You are the Yoga Teacher I aspire to be; you are intuitive, genuine, knowledgeable, and kind. You Are Yoga. I’m so grateful that I chose Yoga Source for my teacher training. It truly was a life changing experience, and I will be forever grateful to you for that.- Much love, Karina Clark
Theresa's teaching has impacted my life in such a positive way. I have been coming to Theresa's classes for many years and always leave feeling inspired and motivated to better my self and areas of my life. I cannot express how grateful I am to have taken her yoga teacher training program. Coming into this program as a very shy person, having struggled with a lot of anxiety and depression, this program really made me look inward and really work on areas on myself that I needed to help myself move forward. Since finishing the program, my life has significantly changed for the better. Stacey Haskell
Theresa is a thoughtful and knowledgeable yoga instructor. She changed the way I practiced by fostering the space to truly explore what I felt in my body. Her classes always have the elements that I need: space to breathe, space to move how I need to, space to rest, space to understand a little bit more about who I am in the world and how to show up with more love. Her mentorship through all of my hours of teacher training has help mould me into the knowledgeable and intuitive instructor I am today. . Crystal McDermott
Theresa is a shining star without a doubt! When I met Theresa back in 2009, I was in need of change, I attended one class of hers, and after that I was hooked... and began practicing with her on a regular basis. Theresa offers yoga in a way that is accessible to everyone, unique and to the point! Her wisdom, free expression in class inspired me to open those same pathways within myself, and for that I would be forever grateful. Taking teacher training with Theresa was exactly what I needed to change my life for the better; and it cleared the path for me to change my life in a way that was unique to me, and inspired by Theresa's bright light! .
