Dr_SpahlAfter having been an orthodontic functional appliance design consultant for the members of the Ohlendorf team for over 30 years, I can heartily attest that there is no laboratory in the country that projects a higher level of skill, knowledge and personal service as the great and historic Ohlendorf Appliance Lab of St. Louis, Missouri.

The members of the extensive Ohlendorf team possess a most impressive and veteran background of knowledge and experience of all types and techniques of orthodontics and appliance therapy, both fixed and removable. The extent of their knowledge of both the diagnosis and treatment of any type of malocclusion never ceases to amaze me. They listen to every orthodontic speaker, read every orthodontic text book, and see the work that comes into their laboratories from orthodontists, TMJ experts (their splints are fabulous), as well as the orthodontic work of general practitioners from all over the country. As a result, they have an unfathomably vast experience in knowing what works and what doesn’t work! They will do anything to help you on difficult cases, (even to the point of telling you that your might be making a mistake if you actually are).

They want you to do well, so that in turn they can do well. They have diagnostic experts with 80 years of experience “in the trenches”. They deserve to be highly respected as the “go to” laboratory for anyone involved in orthodontics and/or “TMJ” endeavors. They have what it takes to be a leader in this field. Quite frankly, they are among the most sincere, friendly, knowledgeable, and “stand up” people I know in this business. They earn the highest “Marks,” (and Kevin and Al are no “slouches” either)! I am more than pleased to give them my highest recommendation!
