Our Team

Dr. Wiessner is a longtime optometrist in Walla Walla, known for his steady, patient-centered approach to eye care.

He enjoys building lasting relationships with patients and helping them maintain healthy vision through every stage of life.

A Walla Walla native, Dr. Wiessner grew up in a German-speaking household after his parents immigrated to the United States in 1954. He first learned English when he began kindergarten, and went on to attend local schools before studying at Whitman College. He later completed his Doctor of Optometry degree at Pacific University College of Optometry.

Outside the clinic, Dr. Wiessner has a deep love of music. He is an accomplished pianist and church organist, and music has long been a central part of family life. His wife, Becky, is a violin teacher and performs with the Walla Walla Symphony. Together, they enjoy making music with family and participating in local bluegrass groups.

Dr. Wiessner and his wife have two sons, both of whom followed careers in optometry – one practicing locally at Vision Source Walla Walla, and the other practicing in Ireland.

Dr. Danny provides comprehensive eye care with an emphasis on practical, personalized solutions for patients of all ages.

He enjoys helping people not only see clearly and live well, but also better understand their eye health and the options available to them — whether that’s glasses, contact lenses, or medical treatment.

He earned his Bachelor of Science in Biology before completing his Doctor of Optometry degree at Pacific University, and has been practicing in Walla Walla since 2014. At Vision Source Walla Walla, he works alongside a dedicated team to deliver efficient, thoughtful care in a welcoming environment.

Dr. Wiessner has a strong interest in blending medical eye care with everyday visual needs, and values using technology and clear communication to make visits straightforward and comfortable.

Outside the clinic, he enjoys spending time with his wife and four children. His interests include music, video games, and creative projects involving digital art and design.

Dr. Judy Quach grew up in Gilbert, Arizona, and earned her undergraduate degree in Ecology and Evolutionary Biology from the University of Arizona.

Although she initially explored interests in art, veterinary medicine, and research in animal behavior, she was ultimately drawn to optometry by her interest in healthcare, her love of helping people, and the opportunity to make a difference in patients’ daily lives.

She received her Doctor of Optometry degree from the Southern California College of Optometry in 2018. Her clinical training included vision therapy in San Diego, as well as rotations at a VA hospital in Long Beach and an Indian Health Service site in New Mexico. Dr. Judy enjoys creating a comfortable, easygoing experience for her patients while helping them feel informed and well cared for during their visits. She has a special interest in myopia control and binocular vision dysfunction.

During optometry school, she met her husband, Jason (thanks to Pokémon Go!), and they quickly bonded over their shared love of music, gaming, and travel. Outside the clinic, Dr. Judy enjoys spending time with her husband, Jason and their son, Wren. She’s an avid gamer who often spends her weekends playing online with friends, but she also enjoys getting outdoors to hike or tend to her garden. In her free time, she likes drawing/sculpting, taking on DIY projects, attending concerts, and going to video game conventions whenever she can.
