Meet Natalie
Meet our Team
Dr. Natalie Marshall is the founder and owner of Vitalize Physical Therapy. A proud Hoosier (but really a Boilermaker), Natalie returned to Indiana after several years away and quickly recognized the need for high-quality, hands-on physical therapy that isn’t dictated by insurance limitations. In 2016, that vision led her to create Vitalize—where personalized, holistic care empowers patients to thrive.
​
Natalie’s patients often describe her approach as intuitive, holistic, and deeply compassionate. She is committed to uncovering the root cause of both pelvic and orthopedic issues so her patients can return to the activities they love—without pain, limitations, or embarrassment. A lifelong learner, she regularly pursues continuing education and blends evidence-based research with innovative, integrative techniques. Her care philosophy brings together the best of both "east and west" in modern physical therapy.
​
Natalie earned her Doctorate of Physical Therapy from Belmont University in Nashville, TN, and her Bachelor’s degree in Movement and Sports Science from Purdue University in West Lafayette, IN.
​
Outside the clinic, Natalie loves spending time with her husband Ryan, daughters Gianna and Colette and goldendoodle Hadley, summer weekends at the lake, barefoot walks and grounding, being outside in nature, herbal tea, local restaurants, interior design, deep conversations with friends, and never misses a chance to talk about her 3 favorite topics (pee, poop, and sex)!
Dr. Katelin Koontz brings seasoned clinical expertise and a passion for whole-person care to the Vitalize Physical Therapy team. A Pennsylvania native, she earned her Doctorate in Physical Therapy from Saint Francis University, where she also met her husband, Zach. Together, they’ve lived in Dallas and Chicago before settling in Indiana—Zach’s home state—to raise their family.
​
Katelin is passionate about helping patients feel seen, heard, and truly supported in their care. She believes physical therapy should be personal, empowering, and rooted in whole-person healing—not a one-size-fits-all experience. With a compassionate approach and a focus on real results, Katelin partners with her patients to uncover the root of their concerns and guide them toward lasting relief, confidence, and vitality. She is passionate about bringing awareness around pelvic floor health and help more people access empowering, evidence-based care. Katelin believes in combining advanced clinical knowledge with a compassionate, personalized approach to support her patients through every stage of life.
​
Katelin holds several advanced certifications, including Orthopedic Clinical Specialist, Pregnancy & Postpartum Corrective Exercise Specialist, and Thriving Mama Provider. She is a lifelong learner who continues to deepen her expertise through specialty coursework and hands-on training.
​
Outside the clinic, Katelin enjoys time with her husband and their three boys—Henry, Jackson, and Waylan—whether cheering on the sidelines at sports events or relaxing at home with their two German Shorthaired Pointers. She also loves gardening, being in nature, exercising, visiting her family’s farm in Ohio, and exploring new ways to live a vibrant, balanced, and healthy life—and she’s passionate about helping others do the same.
Dr. Laura Grabowski has been a part of the Vitalize Physical Therapy family since May 2019. She followed her three older siblings to Purdue University for undergrad and then went on to Duke University where she achieved her Doctorate degree in Physical Therapy. After working in Memphis, TN for a year at a Pelvic Specialty Clinic, Laura moved back to the Indianapolis area in 2016 to best fulfill her duties as the world’s greatest aunt.
​
Her patients say she is thorough and approachable, creating an effective and safe environment for therapeutic healing. Patients are impressed with her whole body approach and ability to explain the depth and interconnected nature of the body to the mind. Laura has a drive for learning all she can about the human body so that you can feel better faster while still honoring the natural healing process. After completing multiple pelvic floor continuing education courses, she became a Board Certified Clinical Specialist in Women’s Health Physical Therapy (WCS) in July 2018. She also has training in trigger point dry needling, visceral manipulation and craniosacral therapy; providing a more complete and holistic approach to physical therapy.
During her free time, you can find Laura doing yoga, spending time outdoors, and listening to podcasts. She enjoys hiking with her husband, AJ, and their two dogs, Harvey and Poppy. She is a mom to Margo and Aiden. Laura loves learning about other cultures -- especially trying new foods! Laura’s big family and extroverted nature keeps her social calendar busy with birthday parties, weddings, and long weekend adventures.
Dr. Katye Tuyo is happy to be a part of the Vitalize Physical Therapy family, with a passion for getting to the root cause for true healing to happen. Born into a family that bleeds Black and Gold, she attended Purdue University where she graduated with a degree in Athletic Training. It was there she discovered a natural ability to feel what is happening below the skin and a love for manual therapy was born. She continued on to the University of Indianapolis where she achieved her Doctorate degree in Physical Therapy. Upon graduation from UIndy, Katye remained in the Indianapolis area treating patients with orthopedic and pelvic health conditions, continuing to grow her holistic approach to help patients heal.
Her patients say she is a good listener and uses a personalized hands-on method. She focuses on creating an optimal environment to enable the body’s innate healing process. She takes a “zoomed-out” approach in order to determine contributing factors, while simultaneously focusing on the root cause of symptoms. Katye is a lifelong learner, stays up to date on current research, and loves continuing education to learn new techniques and perfect her skills.
​
When not at the clinic, you can find Katye spending time with her dog Harvey. She enjoys traveling, going on family trips, rollerblading with her pup, advocating and educating on non-toxic personal products, and growing her own fresh veggies in the garden. On Saturday mornings you will likely find her at one of her favorite places, the farmer’s market, where she enjoys trying new foods and supporting the local community.
Kristin Vance joins the Vitalize Physical Therapy team as our Client Experience Manager. She loves being part of a team that is dedicated to helping others. She has a passion for supporting people in their journey towards positive change and a healthier life.
Kristin attended Hope College where she earned her Bachelor's degree in Psychology. She continued on to Trinity University where she achieved her Master’s degree in Counseling Psychology. She has taught and worked in college counseling centers with a collaborative focus on assisting and supporting students to navigate their college journeys and life. Most recently Kristin worked in the mental health field as a coach, combining her education with her passion for holistic healing. Patients who engage with her find her genuine and leave feeling heard, valued and encouraged.
When not at work you will find Kristin spending time with her favorite people - her husband Fred and kids Will, Sam, Calvin and Lili. With two of her children being in college she splits her time between cheering for Ball State and Purdue. She loves traveling, hiking, singing at her church, being on the beach, trying out new restaurants and cuddling with her cute Cockapoo named Obi.
Hadley Rose is our Canine Executive Officer (CEO). She's been with the Vitalize team since the beginning and is arguably the most important part of therapy. She is always happy to greet each patient with a few excited barks, proceeded by tail wags, spins, and kisses. She loves affection and “touch” is her love language. Belly rubs are her all-time favorite!
​
Once she helps patients feel welcomed, she is ready and eager to help them safely reach their treatment room. She will make sure you are comfortable at the beginning but is not afraid to sleep on the job to conserve her energy. Don’t worry, if you ever need a distraction during an awesome dry needling session - she's your girl! She has a sixth sense for needling and has trained herself to wake up when she is needed for comfort. Beware if you lock eyes with her . . . she has a way of staring deep into your soul.
​
​She enjoys playing with toys (her current favorite is a loud squeaking furry badger), hanging out and snuggling with mom, dad, Gianna and Colette, watching and interacting with dog movies, smelling and kissing babies (especially if they coo or cry), playing in creeks and lakes in the warmer months, observing squirrels and occasionally chasing them, and being the center of attention everywhere she goes (partly due to her cuteness, and partly due to the fact that she is a Leo).
