Meet the Doctors
Dr. Allison Begley
I grew up in Omaha, Nebraska, and attended Creighton University for both my undergraduate and dental degree. I studied exercise science and sociology before attending Creighton Dental School where I graduated in 2025.
I knew I wanted to be involved in healthcare from a young age, but it wasn’t until I spent time shadowing and talking with my childhood dentist that I realized dentistry was the perfect fit. I love building relationships with patients, helping them feel confident and healthy, and being part of their long-term care. Dentistry gives me the chance to work one-on-one with people and make a real difference in how they feel about their smiles.
Outside of the office, I love spending time outdoors with my fiancé, Jacob, and our dog, Sully. We’re always on the hunt for new hiking or walking trails to explore. I was a competitive baton twirler for nearly 15 years, and still teach lessons in my free time! I also come from a big Creighton family — I have three sisters, and all of us went to Creighton, so it’s safe to say… we bleed blue. You’ll definitely find me cheering on the Jays at every Creighton basketball game!
I’m so excited to be part of the Plattsmouth community and can’t wait to meet you all.

Dr. James Landholm
I grew up in Columbus, Nebraska and attended Nebraska Wesleyan University for my undergraduate degree. I studied biology, chemistry and business, and played baseball for the Prairie Wolves. I earned my dental degree from Creighton University Dental School in May 2018.
I hope to develop relationships with my patients that can last a lifetime. My path to dentistry started when I would go to my family dentist in Columbus and see generations of families still coming to him from cities all across Nebraska after years of moving away. Getting to know patients while delivering a healthy smile people can be proud of has always been my goal.
When I’m not in the office I enjoy golfing, discovering new places to eat, spending time with my wife, Ali, and trying to keep up with my two nephews. I bleed Cornhusker red and have grown to be a classic Jaysker after spending four years attending Creighton basketball games. I look forward to practicing in Plattsmouth as I’ve missed the people and atmosphere you get in a smaller community. I can’t wait to meet the patients with a smile and a helping hand.

Dr. Alex Mayhan
I grew up in Omaha, NE and attended the University of Nebraska – Lincoln for my undergraduate degree, and studied biology and psychology. I earned my dental degree from the University of Nebraska Medical Center College of Dentistry in 2016.
My path to dentistry started through experiences with my dentists, oral surgeons, and orthodontist that cared for me when I was growing up. I spent years in braces and had to have jaw surgery, so I was in the dental office a lot. For something that would have been traumatic for many, this was intriguing to me and sparked my interest in the field. I would not have been able to have such an experience if it weren’t for the compassionate and empathetic people that cared for me along the way. I have heard countless stories from my patients of the bad experiences that they have had in the past, which has prevented them from coming to the dentist and has created a life-long fear. My mission is to provide a safe, comfortable, and enjoyable experience and build long-lasting relationships with my patients, as well as delivering top-quality dental work.
Outside of the dental office I enjoy traveling when I can, golfing, cooking and eating as much food as possible, and spending time with family and friends. I have been practicing in Plattsmouth since 2022 and have thoroughly enjoyed getting to know the community and people. I look forward to meeting more and more kind patients and continue to strengthen existing relationships.
