About Me

Couples struggling to get pregnant can feel stressed and isolated and the choices they face can seem overwhelming. That is why it is essential to me that couples have a thorough understanding of the options available to optimize the man's fertility before embarking upon a reproductive plan. Each couple is unique and I work hand-in-hand with our female reproductive specialists to help couples realize their goals. I think it is important to honor the couple's decision and it has been my privilege to help thousands of couples on their journey to grow their families. I have over two decades of experience in microsurgery and I use surgical, medical, and lifestyle approaches in my practice.
