Dianna Aufdermauer

Fashion Design Instructor

I have been in love with fashion since my childhood. I designed my first fashion line and put my first fashion show on when I was five using the fabric scraps from my mother’s sewing projects to create clothes for my Barbies then showing them to everyone in the house. I started sewing proper at fourteen after I asked my mother to teach me how to sew. She gave me some fabric, showed me how to thread the machine, and told me to have at it. And have at it I did. I found my passion and my love in the act of creation and I never looked back. I graduated from the Art Institute of Las Vegas with a Bachelor of Art in Fashion Design and I especially love vintage fashions and circle skirts. Fashion is just one part of my life though; I am an avid learner and recently started learning how to bake sourdough bread. I also enjoy dancing, finding natural ways to take care of my family, and checking things off my bucket list. Oh, and someday I want to be a mermaid.

VaLlarey Gandy

Fashion & Sewing Assistant

Hello, my name is VaLlarey and I have been designing since I was a child. I would create outfits for my cats, much to their disappointment, and parade them in my fashion shows. I must admit they were the best-dressed cats in town.  At age 15 my mom gave me my first sewing machine and I had to learn to sew on my own.  I continued to design and sew throughout my teens making prom dresses, concert outfits, and costumes until I found the Fashion Institute of Design & Merchandising in LA. I spent my first year at FIDM and after a hiatus (becoming a wife and mother), I finished my education at the International Academy Of Design Technology in Tampa, Florida where I graduated with a Bachelor of Fine Arts. I have four amazing children who are artists and designers themselves. Every day they support my design dreams and challenge me to be a better person. I'm an adventurer and love exploring or learning new things. Currently, I am taking a hip hop dance class. When I want to relax I enjoy reading & sketching. I am also passionate about crystals & cats, which I have compared to potato chips as I can't have just one! 


Sarah Wideman

Program Director + CEO

Hello, and thank you for being here! My name is Sarah and I am the mom behind YADCA. My family moved to Las Vegas in 2017 and upon arriving I began looking for classes and activities to participate in that fit my children's interests, which included sewing and cooking. When I found very little offered that fit what we were looking for, I got the crazy idea that I might be able to create a program myself, and thus the vision for YADCA was born. 

I graduated from college in 2004 with degrees in Sociology and Music. I worked for several years with at-risk youth and homeless families, along with teaching piano and violin lessons on the side prior to becoming a full-time mom and eventually a full-time homeschooler.

Once I decided I was going to embark on the new adventure of creating YADCA, I realized I had a significant amount of work and learning to do, considering I have no background in business and am a novice on both the sewing machine and in the kitchen. I began consuming all things business and in early 2019 I completed a program in Holistic Nutrition to help provide me with a better foundation in the direction I wanted for our YADCA culinary programs. I have been very fortunate to find amazing professionals all along the way to help develop and refine our curriculum and teach our classes. YADCA officially launched in the Fall of 2019 and it has been a very educational journey, to say the least! While I have always preferred to be behind the scenes in running the business while our amazing instructors shine on the front lines, I have learned from early on the many challenges of being so dependent on others without having enough knowledge myself in the fields that YADCA teaches. This led me to begin culinary school in 2020 (with expected graduation in 2021) and I am being intensively trained by our sewing/design staff as we prepare for future classes and create our distance-learning platform. Up next will be a better foundation in technology and social media as we are still struggling to become friends!! 

I cannot express enough how grateful I am to all the people who have helped YADCA become a reality and to so many in the community who have been and continue to be so supportive and encouraging of our efforts. You have been incredibly patient and understanding while we tackle the steep learning curve of a new start-up! We will continue to work hard and improve our programs and operations to better serve your families. An extra dose of gratitude goes to my husband and children as well, who continue to be my biggest cheerleader and without whom YADCA would have never been born.

We'll see you in class!
