Welcome and thank you for choosing our practice for your obstetrical care. We want to take this opportunity to introduce all of us who will be involved in your care.

Dr. Don J. Nishiguchi, M.D. (aka. Dr. “Nish” to his patients) and Dr.Jerry K. Izu will be the physicians on the team. They will supervise and orchestrate all your care as well as deliver your baby.

We also have two other team members:

Throughout your care you will be expected to see anyone of the members of our team. However if you develop any difficulties or approaching delivery date, you will be seen by Dr. Nishiguchi or Dr. Izu. Congratulations and thank you once again for choosing our practice.
