Meet the Team at Southside Dental Center


At Southside Dental Care, we are committed to offering you the most comfortable dental experience possible. Our dedicated team doesn't just offer high quality care that improves your oral health – we practice dentistry that is completely personalized to address any problem or concern. We can do this so effectively because each member of our team takes time to get to know you so we can better understand your needs, desires, and priorities. When you speak, we listen!

Our dedicated team understands the value of great oral health, and we do everything possible to help you understand it, too. We like nothing better than seeing our satisfied patients leave our office with a happy, healthy smile. We're happy to share that this year we were recognized by Monticello Times for Best Dentist in Monticello. Please take a moment to get to know us!


Dr. Derek Abramowski

Dr. Derek Abramowski attended the University of Wisconsin-Madison, where he received a Bachelor of Science degree in Microbiology. He received his Doctor of Dental Surgery (DDS) degree from the University of Illinois College of Dentistry. Dr. Abramowski grew up in Buffalo, MN, and always knew that he wanted to return to this area to practice dentistry and serve his community. He is an active member of the Monticello chapter of the Rotary Club, a charity and volunteer organization that regularly participates in programs which benefit the community.

In his free time, Dr. Abramowski enjoys spending time with family and friends. Dr. Abramowski is an avid outdoorsman and often found camping and hiking with his dog, Finn. Much of his winter is spent ice fishing with his wife, son and dog on lakes all over Minnesota.

“I love working with people and having the ability to change their lives. A person's smile is closely tied to their self-esteem, and few other careers offer an opportunity to provide such a drastic and dramatic change as making over someone's smile. I love to work with the new, constantly changing technology in the dental field, and my goal is to make going to the dentist easier and less scary for everyone.” – Dr. Abramowski
