The senior dentist has earned different diplomate and fellowship distinctions. This has also helped him connect with various dental organizations and the privilege of local hospitals.

The Lagina family had four siblings; Rick, Marianne, Marty and Teressa. The siblings were very close to each other from a young age.

All the siblings are currently married. The youngest of all, Teressa is currently married to John. This makes the Lagina family, John's in-laws. With that relationship, John is the brother-in-law of both Rick and Marty.

With this relationship, both the sons of John who have been involved in the show for a long time are the brother's nephews. And both Rick and Marty love their nephews very much.
