T&K Therapy Team

Tristy Carroll Founder and Speech Therapist

Tristy Carroll, Founder and Speech Therapist

Hi! My name is Tristy Carroll. I have been a speech-language pathologist for over 27 years. I graduated with my Bachelor's Degree from San Diego State University and obtained my Master's in Communication Disorders from the University of Oregon. I hold my Certificate of Clinical Competence from ASHA, our national organization, and am licensed in North Dakota to practice speech therapy.


I have a passion for working with young children. My favorite working moments are related to helping a child say their first words. Nothing is better than witnessing a child say mama or dada or love you for the first time to their parents. I strongly believe that parents should be a part of therapy; we are on the journey together. I want parents to enjoy being with their children and feel "speech homework" should be a natural part of a family's day.

My recent coursework includes working with children with verbal apraxia, tongue and lip ties, early intervention, feeding, phonological delays, SOS feeding approach, and autism.


In my spare time, I love to read and spend time on the beach somewhere. My favorite place has been Jamaica--but there are many more adventures to come.

Kristy Lorenz founder of T&K Pediatric Therapy founder and speech therapist

Kristy Lorenz, Founder and Speech Therapist


Hi. My name is Kristy Lorenz. I have been a practicing speech-language pathologist since 2001.  I completed my undergraduate degree in Speech-Language Hearing Sciences at Moorhead State University in 1999 and went on to receive my master of science in Communication Disorders in 2001. I am licensed by the North Dakota State Board of Examiners as well as nationally through the American Speech Language Hearing Association (ASHA). 

I became a speech therapist because someone very dear to me has been a lifetime stutterer and it sparked my interest in helping others with communication disorders.   I saw firsthand how a communication disorder can impact an individual's life and I want to help all children that I see to develop strong communication skills.  All individuals should have a voice! 

I feel that speech therapy services provide a ripple effect, throughout the lives of our clients.  The achievements my clients make in their speech therapy program will not only impact them now but will continue with them so they can reach their highest potential.  I enjoy working alongside families to help them encourage their children to meet goals and make use of the skills we are working on in therapy.  The relationships built with the families are a key component to a successful speech therapy program. 


Some of the topics I have received additional training in are as follows: apraxia, stuttering, feeding, tongue tie identification and treatment, and orofacial myology. 


When I am not working, I enjoy spending time with my family and friends.  Our family likes to be outside and often camp, hike and kayak. 

Carly Stoehr MS CCC-SLP Speech Language Pathologist
Carly Stoehr, MS, CCC-SLP,
Speech-Language Pathologist

Hi! My name is Carly Stoehr. I have been a speech-language pathologist (SLP) since 2016. I graduated with my Bachelor's and Master's degrees from the University of North Dakota. I hold my Certificate of Clinical Competence from ASHA, our national organization and am licensed in North Dakota to practice speech therapy.

One of my favorite things about being an SLP is helping children to communicate and be understood by others through all means of communication. I love learning and finding new ways to help my clients and their families. We will work together as a team to help your child learn and be successful as possible.

I have taken additional education courses on the oral-motor mechanism, including tethered oral tissues and PROMPT

therapy which focuses on using touch cues to help treat children with severe motor speech impairments.


In my spare time, I love to read and online shop. I also enjoy spending time with my husband, daughter and our dog.

Kayla Dockter Speech Therapist

Kayla Dockter, Speech Therapist





My name is Kayla Dockter. I graduated from Minnesota State University Moorhead with my Bachelors in speech language hearing sciences in 2009 and Masters in Audiology and Speech-Language Pathology in 2011. I hold my Certificate of Clinical Competence from ASHA, our national organization and am licensed in North Dakota to practice speech therapy. I have worked with children ages birth to 5 for the last 9 years in Wyoming prior to moving back to North Dakota to be closer to family. 

I enjoy working with children and building relationships with the whole family. Watching a child start out frustrated and unable to express themselves and then build confidence while becoming a successful communicator is the reason why I work in the Speech Language Pathology field. I have completed the Greenspan floortime training as well as Picture Exchange Communication (PECS) training to broaden my skill set. 

In my spare time I enjoy spending time with my family and watching my 4 children grow in various activities. I also like to go golfing and do anything on or near water. 

Occupational Therapy

Amanda Mindt NBCOT Occupational Therapist

Amanda Mindt, NBCOT
Occupational Therapist




Hello! My name is Amanda Mindt. I have been an Occupational Therapist for 7 years. I graduated with a degree of Master of Science in Occupational Therapy from University of Mary in Bismarck, ND. I hold my Certificate for Occupational Therapy through the National Board for Certification in Occupational Therapy (NBCOT) and I am licensed in North Dakota in Occupational Therapy.

I have a passion working with kids and helping them reach their highest potential in their everyday lives. I am a huge advocate for educating and teaching families techniques to adapt a skill that is harder for the child to accomplish. I love to problem solve and come up with solutions. It is very rewarding to help come up with a solution and to see a child succeed and become that more self-confident in themselves.

I have worked in a variety of settings as an Occupational Therapist. I have worked and currently work in a pediatric private practice along with working in a nursing home setting and in the school system. 

I have taken an array of continuing education courses that include topics on sensory, social skills, feeding/oral motor, school-based Occupational Therapy, reflex integration, challenging behaviors, approaches on how to treat children with varying disabilities, etc.


In my spare time, I love to spend time with my family. I am a proud mom and auntie. I also love to craft and try new recipes on pinterest. I love to go thrift store shopping and go to antique stores to find hidden treasures! I also live in the country and raise chickens with my husband.

Kenady Waldie Physical Therapist

Kenady Waldie, Physical Therapist



Hi! My name is Kenady Waldie. I have been a licensed physical therapist in North Dakota since November of 2022. I have graduated from the University of Jamestown twice. Go Jimmies! In my 7 years there, I earned my Bachelor’s degree in Exercise Science in 2019 and obtained my Doctor of Physical Therapy degree in 2022.

I have always loved working with kids. Not only are they the most funny and genuine small human beings, I am astonished every day at how determined and resilient they are through their countless battles. There are many activities and skills that may seem small to adults, and they are things that we take for granted. Enjoying sports and games with their peers, navigating their schools and homes, and exploring their environment are all so crucial to their development. I believe that this will look different for every child, and my favorite part of physical therapy practice

is finding ways to maximize their movement potential according to their individual strengths and needs. 

My recent coursework has included Pelvic Floor Level I Rehabilitation through the Herman and Wallace institute, pediatric spine conditions, and early intervention. In my free time, you can find me crocheting and crafting, playing guitar with my husband, or taking my dog Koda on walks.

Hello!  I'm Brita Goss and I am a licensed mental health counselor (LAPC).  I graduated with a BA from Concordia College in Moorhead, MN and then pursued a MS degree in Clinical Mental Health from Capella University in 2023.  I have taken courses on implementing play therapy into sessions and have additional training in suicide prevention.  I have also received a level 1 certificate from CCEF  for biblical counseling. 


I have pursued this career because I have always had a passion for working with children.   We have all experienced bumps in our path of life, and I want to be used as a tool to help combat these negative childhood experiences so that the child and family are equipped for future life successes. 

In my free time, I enjoy being with my family and pets.  I also enjoy flower and vegetable gardening and reading books when the weather isn't favorable.

Childhood matters, and experiences in the younger years are building blocks for the future. My passion is to help children and families work through difficult events and understand each other better so that they might have the resources they need to work through whatever life throws their way.   

When not working, I like spending time with family and friends. You’ll find me outside as much as possible when the sun is shining and indoors making myself as warm as possible in the winter.

what inspired her career path of Early Intervention. When her brother was one year of age, he started on his journey of early intervention. It was the individuals that provided services in the home which made an impression on Heather to pursue her career. They helped him learn to talk and so much more, but it was the relationships those professionals created over the years with her family that made the difference.

Lacie Walker Early Intervention Executive Assistant ​
Lacie Walker
Early Intervention Executive Assistant

Hi my name is Lacie- IE. I have always had the passion for working with kids for as long as I can remember, whether babysitting my sister or all the neighbor kids. I attended Fort Ransom-Lisbon School and graduated from Jamestown in 2006.  Right after graduation I began working with individuals with developmental disabilities or delays. Looking to add to my experiences I took a job with an Early Education program for children birth to 5 years old in 2011, where I worked for 11 years. I started as a Teacher’s Assistant and 5 years later was ready to take the role of a Teacher. I acquired my 0-5 Child Development Associate and was ready to try something more. After the birth of our one and only beautiful rainbow baby, I took a position as The Family Service Provider which quickly transitioned into 0-3 Supervisor. I enjoyed my years with this program but was ready to learn some new skills while still working with children and their families. I accepted the position as Early

Intervention Executive Assistant with T & K Pediatric Services in February of 2022 and have loved every minute of my career change.


I currently live in Jamestown with my Husband Brent,  our daughter Avaleigh and our 2 dogs Nila & Mayah. I enjoy being happy, making people laugh or smile, going to the post office in the morning, being outside, fishing, camping, attempting to garden, crafting and thrifting. I especially enjoy trips to South Dakota in hopes to someday live there.

Hi! My name is Kari Archambeau. I have been the Billing and Credentialing Specialist for T & K since 2022.

Before coming to T & K, I worked as an Office Assistant in the Business Office at South Central Human Service Center. I am thankful everyday for the opportunity to work with the wonderful people here at T & K and to be able to witness the growth of all the kids that are seen here. 


In my spare time I enjoy spending time with family (telling “dad jokes” to my niece and nephew is my favorite), reading (Stephen King, Dan Brown, and Victoria Schwab), watching movies (horror is my favorite genre), and relaxing with my two cats, Salem and Koda.
