Pam Wiens and Sandy BarberPam Wiens and Sandy Barber

Pam and Sandy each began working in the eye care field in 1988. They have a wide variety of clinical experience from working in many different areas.  Pam began working for Grene Laser in 2002, and Sandy started in 2003.  You will meet each of them on the day of your evaluation.  Pam will start the process by taking you through eye testing prior to meeting with Dr. Kesler.  Sandy and Dr. Kesler will discuss the results of the eye testing and evaluate your ocular health. If it is determined that you are a good candidate for a refractive procedure, you will meet up with Pam and Sandy again on the day of your procedure.  Sandy works with you on preparation for the procedure, making sure you feel comfortable.  After the procedure, she insures that you have your post op instructions.  Pam is in the surgical suite during the procedure.  She programs each patient's individualized plans, chosen by Dr. Wellemeyer, into each laser, and insures the process runs smoothly.  She will be the familiar voice during the procedure.  Post operative care is continued with Pam, Sandy, and Dr. Kesler.  They each have a vital role during your entire experience with Grene Vision and look forward to making it a great experience for every patient.
