Meet our mascot, ESPiN! You may see ESPiN at local sporting or community events meeting and greeting people. Snap a selfie with ESPiN and give our mascot a high five! Hugs are welcome, too. BIETSCH Orthodontics wouldn't be the same without our smiling, spirited friend. ESPiN loves to see patients of all ages with brilliant new smiles and is available in the office for patients when they may need a little encouragement during their treatment.
