Kali Guilmet-Talbot, LCHMC, MS

Regional Clinical Director

I joined the clinical team in 2021. I work with clients living with substance use and mental health disorders, offering a trauma-informed model of care that incorporates cognitive behavioral therapy, motivational interviewing, narrative therapy, and family therapy. In using an eclectic approach, my goal is to develop a collaborative treatment team, providing a supportive recovery environment for our participants.

I have 25+ years’ experience implementing clinical care and program management within behavioral health systems. My areas of expertise are substance use, persistent behavioral health needs, trauma, families, and the military community. I am passionate about recovery that is truly person-centered. I aim to develop programming that is collaborative and creative.
I love the work and continue to find myself excited about opportunities to grow and learn. I find it very important to work in a system that resonates with my core values, including person-centered care. When I speak with the leadership and staff at programming, I am excited to be with like-minded people. There is a passion for excellence, continued growth, and dignity in the recovery process that made me want to work here.

What drives your passion to work in this field?

I have always enjoyed being in a helping role and watching people overcome addiction and mental health disorders. When working with substance misuse clients, my goal is to help clients learn the needed tools for recovery and to hopefully preserve a life. I am grateful to receive a paycheck helping others, but also to learn and grow as much as possible. I hope to give my clients the very best care in the short time I am with them so they can once again lead a productive and sober life.

What makes TruHealing’s programs stand out?

The thought of having a program that genuinely cares about people who made “bad” choices. and wants to see them live and be successful, satisfies me to no end. We offer detox to several drop-down options once people are on the road to recovery, which leaves no client left behind and ensures a client can be successful in sobriety. I want clients to overcome and be well and TruHealing allows me to help do that with these folks every day.

What is the most rewarding part of working at New Hampshire Detox?

I enjoy the newness of NH Detox and working alongside colleagues who have the same agenda of helping clients overcome addictions and lead successful, sober lives. It doesn’t take much energy to do a job you love, and to watch clients successfully complete treatment and prepare them for the next stage of recovery.

What clinical areas of expertise do you have and enjoy working with most?

I have over 30 years of administrative and program development and clinical care experience and have supervised behavioral health programs for both non-profit and for-profit organizations. My expertise encompasses substance misuse, behavioral health, trauma, and persistent mental illness for teenagers and adults. I utilize a person-centered approach by promoting the use of evidence-based practices.

I have worked with children, youth, and families since I was a senior in high school. I watched my parents, who were licensed independent clinical social workers, work their whole lives to assist those who were suffering. I have that same gene and receive personal satisfaction knowing I tried to make a person’s life better.

It is extremely rewarding to work with clients from admission to discharge, and to help them reach goals for discharge and aftercare.

Laura DeManche

Operations Manager

My job is to oversee the day-to-day operations of the facility. I make sure we are providing the best care we can to our clients. I assist in many ways to keep our staff and clients happy and safe.

My passion for working in recovery comes from wanting to help others find a new way to live. I am in recovery myself, and I know how important it is to connect with others who share the same experience.

My favorite part of my job is to provide that light in someone’s darkness. When I was at my lowest point in my own life, I didn’t believe I deserved more or that I was worth anything. If it wasn’t for someone else seeing something inside me that I was unable to see in myself, I would have struggled to keep pushing forward at times. I never could have imagined my life being where it is today. I am truly grateful for this company and all the support I have been given to help me succeed in my own life.

Laura DeManche is the Operations Manager at NH Detox in Bethlehem, NH.. She was born in Massachusetts and grew up all over the state of Maine. DeManche moved to New Hamphire as an adult.
