Tom Petrizzo: Tri-County's great reputation is something to build on.

Offering Hope to the Northland

(from the 2014-15 Annual Report, by Tom Petrizzo, CEO)

I came to Tri-County as its new CEO in the middle of the worst winter on record in more than 25 years.

The weather pundits called it the Polar Vortex. In homage to one of my favorite movies, I called it The Big Chill.

In the midst of that bone-chilling cold, I found a kind and inviting workplace home called Tri-County Mental Health. I was warmly welcomed by the Tri-County board, its great team members, and community leaders.

In the seven months I have been at Tri-County I have seen first-hand –

  • Exemplary Clinical Service (Employment Services, HealthCare Home, Mental Health Liaison to name a few)

  • Great Community Impact (Hospital Diversion, Prevention Services)

  • Supportive Community (Northland Chamber, Northland Healthcare Access)

Whenever I tell someone I work at Tri-County, they say “How lucky you are. That’s a great place to work.”

With that fine reputation, comes the need to continue to strive and to achieve more for ourselves and our community.

With that in mind, we have more to create for Tri-County – a foundation, new exemplary services, and new community partners. I look forward to the future with great anticipation for Tri-County and the Northland, no matter how cold it gets...
