    Thank you Dr. Sarah and her staff are great. Very pleasant and professional everybody. They have a very cutting edge equipment to see your eyes from every angle. Even from the inside-out.

    Hands down this is the best customer service I've experienced in my life. On top of that, the optometrist was very knowledgeable, courteous, and thorough. Dr Sarah Olmschenk was da bomb. If you are looking for a change with your optometry, I highly recommend Baseline Vision Clinic. Everyone in the office were super and helpful as well. Their optician was just as awesome!
