I believe that it is also my responsibility to pay attention to a couple’s emotional well-being, acting as a cheerleader if need-be to encourage a couple to keep trying when I believe we will be successful. It also means gently letting a couple know when we have done all that can be done and help those couples explore other parenting options.”

She subsequently received a Master’s degree in Andrology/Embryology from the world renowned Jones Institute in Norfolk, VA. She has experience from a variety of laboratories, including an environmental testing lab in Anchorage, Alaska, as well as a research laboratory studying antigens that cause cancer using PCR in conjunction with DNA microchip arrays here in Seattle. After coming to Overlake Reproductive Health in April of 2002, she observed that one of the main differences she has noticed between this lab and others is the patient contact.
“I greatly enjoy the patient interaction that comes with the territory here at Overlake Reproductive Health. When we meet individual patients that we are attempting to help, there is an added dimension that does not necessarily come with most research-directed laboratories. We constantly are seeing the human side of our work, which allows us to share more fully in the joys and successes of the clinicians’ daily practice.”
