Testimonials

What Craig & Judy has to say

Uncommon Care, Close to Home

Craig and Judy Unger-Clark sit together smiling in a hospital waiting area with snow outside the window. Craig wears a dark sweater; Judy is in a yellow sweater and scarf.

For decades, Craig and Judy Unger-Clark of Rindge have counted on Monadnock Community Hospital for compassionate, expert care. As longtime supporters and members of the hospital community, they’ve experienced firsthand what makes MCH special.

Last year, Judy—an active member of MCH’s Patient & Family Advisory Council (PFAC)—was referred to Dr. Michael Gilbert of Monadnock Gastroenterology Associates for a colonoscopy and endoscopy. The procedures revealed a villous adenoma, a precancerous polyp that required surgery. Dr. Gilbert didn’t just deliver clinical insight—he went above and beyond. Craig recalls, “I was waiting during Judy’s surgery at Mass General, and Dr. Gilbert called me personally, to check in for an update. That kind of concern is uncommon.”

Judy adds, “He also checked in to learn about our meetings with the surgeon. We’re very pleased Dr. Gilbert returned to Monadnock Community Hospital.”

Today, Judy continues her care at MCH, including MRIs and lab work. The Unger-Clarks credit the hospital’s access to local and advanced services as vital to the region’s health. “MCH knows who to send you to,” says Craig. “That is an important part of being a great small hospital.”

The Value of Philanthropy

Craig says his commitment to Monadnock Community Hospital is rooted in his family’s values. “Growing up, my parents were always involved in our community, making donations to the local hospital every year. It’s ingrained in me.”

That legacy became personal when a trip to Colorado highlighted the importance of timely access to care. During the trip, Judy experienced a brain aneurysm. Immediate access to a CT scan saved her life.

They asked themselves, “If this had happened at home, would MCH have been able to diagnose me?” The answer was yes—but the experience inspired them to act. When they learned MCH planned to upgrade its CT scanner, they made a generous donation to support it. Their story is a reminder: giving to local healthcare can save lives.

What Don has to say

A Journey of Hope: A Story of Resilience and Collaborative Care

Don Nalette of Jaffrey has always enjoyed life’s adventures, from practicing long-range shooting and building vintage firearms to peaceful kayaking trips. After years of hauling pre-cast concrete, he was enjoying retirement—until last year, when his life took an unexpected turn.

“I admit I’d been putting off colonoscopies for years,” Don reflects. “Turns out I should have listened to my doctor.”

When Don finally scheduled a colonoscopy, Dr. Michael Gilbert of Monadnock Gastroenterology Associates discovered tumors causing a blockage. Due to the severity of his condition, Don was scheduled for surgery with Dr. Brian Kwitkin of Monadnock Surgical Associates the very next morning.

“Everything happened so fast,” Don recalls, “but I was treated so well by everyone—from the doctors to the nurses. They were all so pleasant, encouraging, and professional.”

He especially appreciated the calm and welcoming atmosphere of Monadnock Community Hospital, which allowed him to receive attentive, personal care in a private room.

After 12 challenging chemotherapy sessions under the care of Dr. Eric Bonnem in the MCH Oncology and Infusion Therapy Center, Don is making remarkable progress. Initially, doctors estimated only a 20% chance of full recovery. However, after liver surgery at Dartmouth Health, his care team is now hopeful for a full recuperation.

“I’m so grateful to the team at MCH for their care and professionalism,” Don says. “They took good care of me.”

Now, with new possibilities on the horizon, Don is looking forward to getting back to the hobbies that bring him joy.
