Our staff of clinical anaplastologists is committed to enhancing quality of life through the art of prosthetics with the highest level of respect for our patients. Our prostheses provide a high quality, customized solution to living with the long-term effects that trauma, disease, or congenital malformations often leave behind.

Will Lakey, MFA, BCO

Will Lakey, MFA, BCO is a board-certified ocularist, specialising in the production and fitting of ocular prostheses (artificial eyes). Originally from the United Kingdom, Will earned a Bachelor of Arts degree at Northbrook College of Fine Arts, in Sussex, England, before moving to Glasgow, Scotland in 2006, where he began his internship at the Tennent Institute of Ophthalmology at Gartnavel General Hospital. In 2012, after 6 years of creating custom prostheses for patients from all across Scotland, Will moved to Minneapolis to pursue a Master of Fine Arts degree at the University of Minnesota. While his primary areas of interest were drawing and painting, he discovered a passion for 3D design, 3D printing, and metal casting: experiences and skills which have proved valuable in his position at Prosthetics at Graphica Medica. Will is passionate about refining his skills, constantly seeking new and improved processes for the manufacture of ocular prosthetics. Will enjoys reading and watching science fiction, walking his rescue greyhound Sam, and of course drinking tea, but only black tea (with milk).


Graphica Medica was founded by Gillian Duncan in Homburg, Germany in 1981 as The Institute for Medical Illustration and Craniofacial Epithetics.  Gillian directed the institute in Germany for 14 years, where she introduced the “American approach” to fabricating and fitting facial prostheses.  In 1991, Gillian relocated to Rochester, MN, where she established Graphica Medica, LLC to provide medical illustrations and facial prostheses to physicians and their patients in Minnesota, and later, the 5-state region including North and South Dakotas, Iowa, Nebraska, and Wisconsin.  Today, Prosthetics at Graphica Medica provides facial and somatic prosthetic treatment to patients nationally and internationally. In 2016, Michaela Calhoun took over the practice after nearly 6 years of working with Gillian. The practice continues today in the spirit that Gillian set forth: enhancing quality of life through the art of prosthetics.
