Undergraduate Education: Worcester Polytechnic Institute; Bachelor of Science, Electrical Engineering. Optometry School: New England College of Optometry, 2008. Professional Achievements and Associations: American Optometric Association; New Hampshire Optometric Association. Clinical Certifications and Specialties: Dry eye specialist. The reason I became an optometrist is: I became interested in vision after doing a research project involving a protein like rhodopsin, a visual pigment molecule that ultimately helps us to see. Additionally, my father was a dentist. Having a parent in the health professions ultimately led me to consider optometry. My favorite part of helping my patients is: I really enjoy prescribing glasses or contact lenses for first-time wearers. That's when I feel that I have the greatest impact on the quality of their lives. By helping them to see, I can truly make a difference, especially with kids. I also enjoy helping to connect patients with other eyecare providers who provide services beyond just glasses and contacts. This includes referring in-house @ MED to optometrists who specialize in binocular vision disorders or specialty contact lenses, or even referring outside of MED to ophthalmology for cataract surgery. Ultimately, my job is to ensure that not only do my patients see their best, but for them to understand how ocular health impacts their vision. As primary care optometrists, we have a broad scope of practice that allows us to prescribe therapeutic pharmaceutical agents (TPAs) for several ocular conditions. It is our job to educate our patients about these conditions and prescribe when appropriate. In my spare time, I enjoy: spending time with my 2 year old daughter; reading; biking; traveling.
