Aaron grew up outside Lewistown and graduated from Highland High School. He graduated from Truman State University before attending Kansas City University, where he earned his medical degree. While in medical school, he also completed an MBA in Healthcare Leadership at Rockhurst University, followed by Family Medicine residency at the University of Missouri-Kansas City.

Aaron’s early career was spent in rural emergency rooms throughout Missouri and Iowa. Those years taught him a lot about taking care of people on their worst days, but they also shaped the way he thinks about primary care. Many of the problems he saw in the ER could have been prevented, caught earlier, or managed better if patients had easier access to someone who knew them.

Two years ago, Dr. Neisen returned to the clinic and hospital setting, bringing with him a wealth of diverse experience to provide comprehensive, patient-centered care. His broad skill set and dedication to serving rural communities continue to guide his practice as he balances his roles in clinical, inpatient, and emergency medicine.

That idea eventually helped lead to Healthspan. Aaron wanted to practice medicine in a way that gave him time to know his patients, answer their questions, and focus on keeping them healthy instead of only treating them when something went wrong. Although, he continues to work in both clinic and hospital medicine, primary care gives him something other settings can’t: the chance to care for people over years instead of hours.

Outside of medicine, Aaron and his wife, Steph, are raising their three boys. He enjoys reading, traveling, golfing, and probably spends more time than necessary thinking about fantasy football. He believes there is something worth preserving about small-town medicine: knowing your patients, being available when they need you, and taking care of the community you call home.

Steph grew up outside La Grange and graduated from Highland High School before attending the University of Missouri, where she earned a degree in Business Administration with an emphasis in finance. After college, she moved to Kansas City and began her career in commercial real estate banking. While working full-time, she earned her MBA from Rockhurst University.

After becoming a mom, Steph eventually stepped away from the corporate world to stay home and focus on raising her family. During those years, she continued managing their family’s businesses and discovered that she really loved building things – businesses, systems, teams, and eventually Healthspan.

After 12 years away, Steph and Aaron made the decision to move their family back to northeast Missouri. Healthspan became part of that. Today, Steph works mostly behind the scenes, overseeing the business side of the practice and helping turn a lot of big ideas into things that work. From finances and operations to staff, community partnerships, events, and the details most people never see, her job is a little bit of everything.

Outside of work, Steph is a wife and mom to three boys, a Taekwondo student, an avid reader, a LEGO fan, and loves to travel. She is passionate about finding ways to make the community she and her family call home a better place to live, work, and raise a family.

Matt’s interest in healthcare started in anatomy class at Highland, although basketball was still a pretty big part of the plan at the time. After graduating from Highland High School, he went on to Culver-Stockton College, where he played basketball for the Wildcats while earning his nursing degree. The NBA never called, but healthcare turned out to be a pretty good plan B.

Matt graduated just as the COVID-19 pandemic began and started his nursing career caring for acutely ill patients in the hospital. It was an unusual introduction to healthcare and one that taught him a tremendous amount about caring for people when they are sick. It also made him increasingly interested in what happens before someone reaches that point.

That interest lead Matt back to school to become a Family Nurse Practitioner. It also made the idea behind Healthspan especially appealing. Instead of rushing from one patient to the next, Matt wanted the opportunity to slow down, know the people he was caring for, and help them work on their health before a problem became a crisis.
As one of Healthspan’s founders, Matt has helped build that approach from the beginning. He enjoys the variety of family medicine and the relationships that come with caring for individuals and families over time.

Outside of work, Matt spends much of his time with his wife, Lexi, and their families. Lexi has become an important part of Healthspan, too, rarely missing an event and always willing to volunteer or make another trip to Design It for Steph’s ever-growing collection of Healthspan merch. Matt’s parents, brother, and extended family are regulars at Healthspan events as well, often walking in parades and pitching in wherever they’re needed.

Stacia is a lifelong Clark County resident, but Lewis County is where she began her career as a Family Nurse Practitioner and spent the first 10 years of her career caring for patients and families in the community.

She earned her nursing degree from Blessing-Rieman College of Nursing in 2002 and her Master of Science in Nursing from Saint Louis University in 2008. After beginning her practice in Lewis County, she spent the next eight years caring for patients closer to home in Clark County. Now, with nearly 18 years of experience as a nurse practitioner, she is returning to Lewis County as part of the Healthspan team.

Stacia especially enjoys the opportunity primary care gives her to know her patients beyond the reason they walked through the door that day. She has a particular interest in disease prevention, healthy lifestyles, and helping people make realistic changes that allow them to stay healthy and feel their best. She believes good healthcare works best as a partnership. With patients having the time to ask questions, understand their options, and be involved in decisions about their health.

Her connection to Lewis County is personal, too. Her husband, Clint, grew up here, and together they have two children. Away from the clinic, Stacia enjoys hiking, gardening, spending time outdoors, and finding ways to serve her community.

After nearly two decades in healthcare, she is excited to once again care for patients and families in a community that was an important part of the beginning of her career.

Adrienn grew up in Lewis County and graduated from Highland High School before earning her nursing degree from Truman State University in 2014. While at Truman, she was commissioned into the Army Reserve through ROTC. Her experiences growing up in a rural community and seeing how difficult it could be to access specialized women’s healthcare helped shape her career.

She went on to Vanderbilt University, earning her Master of Science in Nursing with a specialty in Women’s Health in 2016. Since then, Adrienn has cared for women through just about every stage of life, with experience in fertility and IVF, family planning, birth control, PCOS, routine gynecologic care, sexual health, and the transitions of perimenopause and menopause.

One of Adrienn’s biggest passions is education. After realizing she was answering many of the same questions for women every day, she created No Awkward Questions, an online women’s health resource where she shares practical, straightforward information and encourages women to ask the questions they might otherwise be uncomfortable bringing up. That same philosophy carries into the exam room: there really are no awkward questions.

Adrienn has stayed connected to the community through her work with Healthspan. She returns to the clinic quarterly to see patients in person and provides virtual appointments between visits, giving women in the area access to specialized women’s healthcare that can otherwise be difficult to find in a rural community.

Outside of work, Adrienn enjoys running, spending time with her family, and has a well-documented appreciation for coffee.

Born and raised in Lewis County, Hannah graduated from Highland High School – although plenty of people around here may remember her as Hannah Collier. She earned a degree in psychology from Culver-Stockton College in 2015 before completing her nursing degree at Blessing-Rieman College of Nursing in 2020.

Since then, Hannah’s nursing experience has included emergency medicine and care management, giving her the opportunity to care for people both during some of their most urgent moments and as they navigate their health over time.

Hannah has a particular interest in women’s health, gut health, hormones, nutrition, and the everyday habits that affect how people feel. She has also completed health coach training, which fits naturally with the way she approaches patient care: listening, looking at the whole picture, and helping people find changes that actually work in real life.

Being able to do that work in the community where she grew up is especially meaningful to Hannah. She enjoys getting to know patients over time and helping them better understand their health rather than simply handing them a list of things to do.

Outside the clinic, Hannah is a busy mom to two young boys. She loves going for walks, spending time outdoors, and being with her family. And anyone who knows her knows there is a very good chance a Diet Coke isn’t too far away.

Shannon didn’t grow up knowing she wanted to be a nurse. As her grandmother grew older, she encouraged Shannon to consider nursing because of the way she cared for her. Around the same time, a close friend told her that her personality was exactly what people needed during some of the hardest moments of their lives. They saw something in Shannon before she saw it in herself, and eventually they were right.

Shannon earned her Associate of Science degree from Hannibal-LaGrange University before completing her Bachelor of Science in Nursing through Western Governors University. Her nursing career began at Hannibal Regional Hospital, where she worked in medical-surgical nursing and inpatient rehabilitation. She then spent nine years in home health, caring for people where they were most comfortable: in their own homes.

Those years shaped the kind of nurse Shannon wants to be. She loves getting to know people, hearing their stories, and making sure they never feel embarrassed to ask a question. She has seen how frustrating healthcare can be when people feel rushed, unheard, or unsure about what comes next. She especially enjoys taking complicated medical information and turning it into something people can actually understand and use.

Her philosophy is simple: meet people where they are, be honest when you don’t know something, and figure it out together. If patients remember one thing about being cared for by Shannon, she hopes it’s that she listened and made them feel heard.

Outside of Healthspan, Shannon spends most of her time with her husband and son. She practices Taekwondo, loves scattering flower seeds and seeing what comes up, enjoys making their house feel like home, and is always happy when good food is involved – even if she’d rather eat it than cook it.

Katherine brings a rich and varied background to Healthspan, shaped by decades of experience in education, crisis care, and mental health counseling. She began her professional journey teaching at the North Dakota School for the Deaf after earning her Bachelor of Arts in Elementary and Deaf Education from the University of Northern Colorado. But it was her deep care for people and their emotional well-being that eventually led her to complete a Master of Arts in Mental Health Counseling at Colorado Christian University.

Since 2015, Katherine has worked as a self-employed licensed professional counselor, offering clients a compassionate and grounded space to process life’s challenges. Her work has included serving as a program coordinator for the crisis stabilization unit at North Range Behavioral Health, where she supported individuals navigating acute mental health needs. Katherine is also a certified equine therapist through the Gestalt Equine Institute of the Rockies and has a special interest in combining traditional counseling with the healing presence of horses.

Whether she’s working one-on-one with clients or connecting with families, Katherine is known for her warmth, wisdom, and calm presence. She’s excited to bring her passion for mental health to Healthspan as part of our expanding commitment to whole-person care.
