Our History

Allegheny Orthodontic Associates is an orthodontic practice that was founded in 1956 by Dr. Dalton Blough. There are three offices located in, Johnstown, Altoona, and Somerset, PA.  The practice has been cared for over the years by Dr. Blough, Dr. Faber Little, and Dr. Scott Little. Dr. Matthew Radkowski joined the practice in 2006, and assumed leadership of the practice in 2012.  Allegheny Orthodontic Associates has always been a part of the communities where we have served thousands of Western Pennsylvania children and adults. For decades, we have stayed committed to our tradition of emphasizing personalized patient care, coupled with the incorporation of advances in the arts and science of orthodontic treatment.  To go along with our traditional method of braces treatment to achieve beautiful smiles, our fully digital office is the area's leader for Invisalign treatment for teens and adults.  AOA is also a member of the prestigious Schulman Group, a select national orthodontic organization for top practices to collaborate and share ideas.

Exceptionally pleased with my 2-year orthodontic treatment at Allegheny Orthodontic Associates! The staff feels like family and are always helpful explaining care regimens and conveniently scheduling appointments. Through the uncertain challenges they faced during the COVID19 pandemic they continued to provide top notch care and a spotless facility as usual! I’m enamored with the results of my smile and have no doubt it was due to all of the diligent care and precise work of Dr. Radkowski and his team! I can not say Thank you enough!

"I recently was seen at this orthodontist office, and I can honestly say they're the nicest people ever. They were so genuine, and had spoken to me as if I had been going there for years. Their facility is so big and clean. I absolutely love all of the people that work there because they make you feel so welcomed. I would highly recommend anyone to go to Allegheny Orthodontic Associates. Very satisfying place! "

"All 3 of my children have been through orthodontic treatment at Allegheny and we couldn't be happier with the results. The staff were friendly and accommodating. Each child completed their treatment earlier than anticipated, and have beautiful smiles that will last a lifetime! I have recommended this office to many of my friends."
