- Yeah. Triplets. Always a headache with triplets. Just glad they're your patients, not mine.
- — Dr. K. in The Right Thing to Do
Dr. Nathan Katowsky was Rebecca's OB while giving birth to the triplets.
He substituted for Rebecca's OB, and even though at first they found him odd, they grew fond of him pretty quickly. He even helped Jack and Rebecca when Randall didn't want to breastfeed at the beginning.
He lost his wife a year before he met the Pearsons, and found it difficult to go on with his life without his wife.
