Dr. Bill BerkDr Bill Berk

William Berk, OD, Diplomate of the American Board of Optometry, is accomplished with resolving contact lens challenges. He also has a special interest in glaucoma diagnosis and management, as well as finding solutions for binocular vision problems that may have been previously over-looked.

Dr. Bill grew up in Nevada, and moved to Oregon to attend Pacific University College of Optometry, where he met his wife, Dr. Anne. In 1985, they established the Eastside Vision Source practice. They expanded the practice to the Sunnyside Vision Source location in 1991.

Patients with eye disease or corneal distortion that prevents good vision with spectacles require a high level of expertise and experience in contact lens fitting. Dr. Bill has enormous patience and skill, and works tirelessly to design the contact lens and/or spectacle system which will produce that best comfort and visual acuity possible for each patient.

Dr. Berk also takes excellent care of the glaucoma patients in the practice. He diagnosed his father with early-onset glaucoma in the 1980s, and worked diligently to learn all that he could about diagnosing and managing the disease since that time. He has continued to monitor all of the latest research, diagnostic equipment, and treatment options. His skill and care with each patient, treating the whole person and not just the eye, has earned him loyal and appreciative patients.

His interest in optics led to a hobby in photography that became a sideline in recent years. The photographs in the office were created by Dr. Bill. He is fascinated by light, and how the camera sees images differently than the eye.

Dr. Bill became a Diplomate to the American Board of Optometry in March 2014, after rigorous study, evaluation, and testing. This effort exemplifies his determination to stay on top of his profession, re-affirm his love for the discipline of optometry, and continually strive for better knowledge to serve his patients.

Dr. Anne Berk

Anne Berk, OD, Diplomate of the American Board of Optometry, is a problem-solver by nature. If a patient has a difficulty with an aspect of their vision or eye health, she enjoys finding the cause and determining the proper course of action. Dr. Anne takes an interest in her patients’ comfort and appearance, as well as their visual function. She is concerned with the whole patient, not just the eyes.

Dr. Anne is especially interested in the diagnosis and treatment of Ocular Surface Disease (OSD), otherwise known as “dry eye”. Controlling OSD can be difficult, and Dr. Anne is dedicated to educating patients on their options, and working with them to reduce symptoms in the easiest ways possible.

A history of migraines makes Dr. Anne especially empathetic to patients who suffer from headaches. She has expertise in determining whether there is a visual component to headaches, and whether eyestrain or ocular disease plays a role in creating them.

Dr. Anne attended Milwaukie High School, Lewis and Clark College, and Pacific University College of Optometery. She enjoys practicing optometry in the community in which she was raised.

Dr. Anne has achieved national recognition as a knitting instructor/designer. She was certified as a TKGA Master Hand Knitter in 2003. She has created 2 DVDs for Interweave Knits (“Inside Intarsia”, “Intarsia InDepth”), had designs published in magazines such as Piecework, Interweave Knits, and the e-mag “Sockupied”. She travels several times a year to knitting conventions, where she teaches classes on techniques from Argyle socks to Zipper insertion into hand-knits, and is an instructor for Her book, “Annetarsia Knits”, was published in Summer of 2014.

Dr. Nancy BusetDr Nancy garden (1)

Dr. Nancy Buset joined our practice right after graduating from optometry school in 2001. She specializes in pediatric optometry and vision therapy, and she’s been with us long enough to watch some of her patients grow from pre-schoolers to college students!

As a participant in the InfantSEE program (, a nation-wide network of volunteer optometrists providing free exams for babies, Dr. Nancy has done exams on patients as young as two weeks old. She loves to see kids of any age on her schedule, including those who are “only young at heart.” Dr. Nancy comes from a family of teachers, and educating her patients about their eyes and vision is her favorite part of her job.

Healthy Infants

At age 8, Dr. Nancy was already significantly near-sighted, and she remembers the amazement of seeing clearly through her first pair of glasses. In high school and college, Dr. Nancy wore contact lenses. As an adult, she had Lasik surgery ( for more information) to correct her vision. She loves to help her patients explore the pros and cons of all these options, so they can determine which type of correction will best suit their own lifestyle.

Dr. Buset especially enjoys working with students and adults with functional vision problems, such as trouble focusing or aiming their eyes. Vision therapy is like physical therapy for the eyes; it is a powerful tool for resolving many learning-related vision issues, and the results can be very rewarding for both doctor and patient ( for more information).

Dr. Nancy attended Central College in Pella, Iowa, where she majored in biology and minored in French. Through Central’s study-abroad program, she spent a semester in London, studying Shakespeare, art, and architecture. She also took her first step toward a career in optometry there, working one day a week at an optical shop near Buckingham Palace.

As a student at Northeastern State University College of Optometry in Tahlequah, Oklahoma, Dr. Buset was privileged to take part in the campaign to expand optometrists’ scope of practice in that state. After watching the Oklahoma state legislature vote to allow optometrists to perform certain types of laser procedures, she and her classmates put the new law into practice in the optometry college clinic facility, performing advanced techniques that had previously been provided only by ophthalmologists.

Another highlight of Dr. Buset’s optometric education was her senior research project on ocular dominance and its impact on certain types of contact lens fittings. Today, she still uses the techniques she and her research partner developed, when fitting contact lenses for patients over age 40 in our practice.

As a child growing up in Kansas, Dr. Nancy loved to vacation with her family in the National Parks and Forests, particularly out west. In high school, she spent a summer volunteering for the Student Conservation Association, building new trails in the backcountry of Yellowstone National Park. Her love of the outdoors and her wonder at the majesty of nature are what drew her to Oregon, and she hasn’t been disappointed! She enjoys hiking in the Mt. Hood area.

 Dr. Jade Himmelsbach2015 jade Dr profile

Dr. Jade Himmelsbach started working at Sunnyside Vision Source in 2005 as a student at Clackamas High School. For her senior project she taught a class of elementary students about eyes and vision, and was awarded an honors grade for her assignment. She gained experience as an optometric technician and also as an optician working in our clinics.

After PSU, Dr. Jade moved to Forest Grove to attend Pacific University College of Optometry.  While at Pacific Dr. Jade was an active member of AMIGOS, a volunteer group dedicated to provide free vision care and eye health screenings for individuals in third world countries. She visited Costa Rica her second year of optometry school, and loved it so much she lead the trip the following year. Many of the vision screenings were for school children so poor that many of them did not have shoes to wear. Dr. Jade also volunteered on a trip to Guatemala in which the team stayed in a convent and was able to see over 1,000 patients in five days of clinic. Some of Dr. Jade’s best memories in optometry school were on these volunteer trips, and she looks forward to attending more as a doctor.

Specialties of Dr. Jade include diabetic eye health examinations and post-operative cataract evaluations. While on optometric rotations Dr. Jade performed over 800 cataract post-operative evaluations, and received a high pass for her work as an intern at Barnet Dulaney Perkins Eye Center in Mesa, Arizona. She enjoys educating patients on what to expect after cataract surgery, and welcomes all questions from drop dosages to reading glasses.

Another area of interest for Dr. Jade is ocular disease diagnosis and treatment. She has performed specialty testing as a technician at Sunnyside Vision Source for several years, and utilizes her experience collaborating with Dr. Bill on management of ocular diseases.

When not at the office, Dr. Jade enjoys spending time with her husband and her family. A few of her favorite past times include Karaoke and bowling.
