Patient Care Philosophy:

I appreciate the time to connect with each patient one and one and build a relationship where shared clinical decision-making is at the core. While I have the knowledge and expertise to drive decisions, I understand that it is only with a committed patient that the desired outcome can be achieved. I look forward to developing a rapport built on trust and know that I will lead a patient to options that will serve them best.


How I stay well:

I have been active in the cross-fit community for over 9 years. I enjoy traveling, most recently in 2023 to Dubai, S. Africa & Alaska to see the Northern Lights and locally spending time walking/running with our dog Reyna. I have lived in the Lake County area for 15 years with my husband and 2 children.
