Ross English, ODRoss F. English, OD

Northern Hills Eye Care  would like to welcome Dr. Ross English to the practice.     Dr. English is a Black Hills native and is excited to return home to provide comprehensive eye care to Sturgis and the Northern Hills community. He is a graduate of Sturgis Brown High School. He earned his bachelor’s degree in cell biology and neuroscience from Montana State University. Following his degree from MSU, he pursued his optometry training and received his doctorate degree from Pacific University College of Optometry in Forest Grove, Oregon.

Dr. English’s optometric education included much diversity in his clinical experiences. He was trained in hospital-based optometry at the Mayo Clinic in Albert Lea, MN where he managed cataracts, glaucoma, macular degeneration, and diabetes/diabetic eye disease.   The site included an emphasis on neuro-optometry. He did a clinical rotation at the Hot Springs VA Hospital where he had vast experience working with the elderly and the specific problems of the visual system that comes with aging. Dr. English did a clinical rotation at the Norton Sound Health Corp. in Nome AK where he traveled to remote, under-served villages in the Alaskan Bush. This externship gave him the opportunity to practice full-scope optometry to a wide variety of individuals from infants to the elderly. Here he prescribed glasses and contact lenses, and he treated eye disease and infection, ocular trauma, and did vision therapy. Finally, Dr. English worked in a family practice setting at an optometric clinic in Gillette, WY. Here he practiced full-scope optometry but gained much experience working with local surgeons co-managing cataract and refractive surgery (LASIK) patients.

In their free time, Dr. English and his wife Alyssa enjoy taking in many of the outdoor activities that the beautiful Black Hills have to offer.  They have a daughter, Clara, and they love the Northern Hills Community and are looking forward to raising their family here.

Dr. English will be seeing patients Mondays, Wednesdays, and Fridays beginning April 2016!  Appointments can be made by calling our office at 605 347-2666.
