I am a Licensed Clinical Social Worker with a passion for supporting children and families. My work is grounded in attachment theory, and I am trained in the DIR/Floortime approach as well as the PLAY Project, which allows me to meet children where they are developmentally and build meaningful connections through responsive, relationship-based care. I also offer Circle of Security Parenting courses for families who want to deepen their understanding of attachment and strengthen their everyday interactions with their children. I integrate play-based techniques into all aspects of my practice, creating a safe, engaging, and supportive environment for growth and healing. Outside of work, you can usually find me exploring the outdoors with my partner and our three young children. We love camping, hiking, and enjoying all the beauty that Montana has to offer.

Hi, my name is Drew. I am originally from the east coast but moved to Missoula as soon as I feasibly could. My style as an occupational therapist is flexible, fun, and goal-centered. I mainly work with pediatrics but see some adult clients as well. Occupational therapy has an indelible place in human development and I remain in awe of its potential to foster neuroplasticity. I have an advanced certification in DIR/Floortime and use its unique and impactful theoretical framework to guide the bulk of my clinical work. In addition, I am trained in Interactive Metronome, Therapeutic Listening, Foodtime and Astronaut Training. I have Master's degrees in Occupational Therapy and Liberal Studies and consider myself a lifelong learner. When I am not at work, I am likely bagging peaks, petting cats, splitboarding, barbequing, traveling or at a live music event. Thanks for reading.

As a pediatric Speech-Language Pathologist, I work with children from 18 months through 18 years of age. I’m passionate about play-based therapy and specialize in speech sound development, acquisition skills, developmental disabilities and delays, and Autism Spectrum Disorder. I also support literacy development, with a particular focus on children diagnosed with, or suspected of having a diagnosis of Dyslexia. Having been diagnosed with Dyslexia at a young age myself, I understand firsthand the challenges it can create for children and their families. I love building meaningful connections with my patients and watching their skills and self-confidence grow. Outside the clinic, you can usually find me spending time with my family, baking, or enjoying anything involving water. Originally from Glasgow, MT, I studied Communicative Sciences and Disorders at the University of Montana and earned my master’s degree from Midwestern University in Glendale, AZ.

Hi, my name is Mickey LaPan. I am a Speech-Language Pathologist with a strong commitment to providing empathetic, functional, and client-centered care. I completed my undergraduate degree in Child Development and Early Education at Colby-Sawyer College in New Hampshire. My professional path has been shaped by a desire to pursue meaningful educational opportunities in places that also offer a sense of adventure and connection to the outdoors. My clinical work focuses on early intervention, executive functioning, and cognitive-communication treatment, with an emphasis on practical strategies that support participation in everyday life. Outside of the clinic, I enjoy spending time outdoors hiking, rock hounding, paddling, snowboarding, and playing disc golf. I also enjoy traveling to concerts and live music events with my musician husband.

I grew up in St. Ignatius, MT at the base of the Mission Mountain Range. After graduating from the University of Montana, I found a passion for occupational therapy while working as an inpatient rehab aide in a hospital. In 2021, I graduated from the University of Mary with my Doctorate in Occupational Therapy. While mainly specializing in pediatric clients, I’ve also found a niche in helping young adults transition into adulthood. When not in the clinic, you can find me outside fly fishing, canoeing, gardening, hiking, traveling, or hanging out with my two mischievous cats!

Born and raised in Livingston, MT I came to the University of Montana for college and have never left. My work passion is helping clients (and their families) of any age who have neurological impairments from various accidents and medical conditions. I love helping them tackle their daily life problems and find solutions that help them get back to the lives they enjoy. My home passion is my husband, our three daughters and one son-in-law.
