Dr. Berg – Retired

John Woell

I am honored to have so many loyal patients to care for in our community. Our dental practice has many multi-generational families who entrust their oral health to our team.

I believe in treating people with a vision of maintaining each individual’s oral health for an entire lifetime. This requires a comprehensive approach which includes assessing one’s medical, periodontal, orthodontic, and restorative needs. I trained early in my career to diagnose and treat people having malocclusion problems by utilizing orthodontic therapy. Then the reconstructive dentistry is done.

As a native of Morris, I began my undergraduate studies at the University of Minnesota Morris and then continued to the University of Minnesota School of Dentistry. I am an ongoing member of the Seattle Study Club whose educational objective is to use a multidisciplinary approach in treating complex dental conditions. I am also a member of the American Dental Association, the Minnesota Dental Association and the St. Paul District Dental Society.

The profession of dentistry gives many opportunities for volunteering, one of which is to participate at the Hope Dental Clinic (formerly the Union Gospel Mission in St. Paul.) I have also been fortunate to be a team member of Programa San Francisco De Asis Sonrisa on the cleft palate team for over 10 years, along with my wife Marcia. This medical team has treated more than 6,000 cleft lip/palate children in Peru. One other area of mission is to provide preventive dental care for children and adults on an annual basis at the St. Rose School in the Gris Gris community of Haiti.

In addition to my passion for dentistry, I enjoy traveling, cycling, skiing, and all family activities with my wife and our 4 children/spouses and 6 grandchildren.

Elizabeth Woell Rhode

I am fortunate to be a part of the team at Dental Health Care Center. I have had several great mentors in dentistry, and am privileged to work alongside one, my father, Dr. Woell. I find practicing dentistry to be invigorating, and that the real joy of dentistry comes from building relationships with our patients and helping people live healthier lives each day. It is my goal to provide comprehensive care that is suited to each person’s individual wants and needs.

I studied Biology and French at the College of St. Benedict. I moved from Blazer/Johnnie red to Gopher maroon and gold at the University of Minnesota School of Dentistry. I am an active member of the American Dental Association, Minnesota Dental Association, Minneapolis District Dental Society, Academy of General Dentistry, and Spear Study Club. I truly enjoy staying active in continuing education especially through interactive courses.

Outside of dentistry, I love spending time with my husband, Rick, and our two young children. I also have a love of the outdoors and enjoy hiking, yoga, and reading.

Simona Awiszus

As dentists, we give patients back their ability to eat, speak and smile with confidence. Educating patients about prevention and the connection between oral and general health, while delivering a positive and comfortable experience is my main focus. The most rewarding experience is the relationship that develops with our patients.

I am passionate about treating children, starting good oral habits at a young age, and the early diagnostic/correction of sleep-disordered breathing; which reduces the impact of snoring and hyperactivity disorder in children. Early orthodontic treatment also provides better dental alignment and facial development.

Originally from Romania, I came to the University of Minnesota in 2000 to attend a dental graduate program and a Master’s degree. In addition to my 20+ years of practicing in St. Paul, I have studied and received advanced certifications involving new technologies and approaches that will broaden the services offered to our patients.

Outside of work, I enjoy spending time with my husband, our family and friends, traveling, reading, swimming, and skiing. My dearest cause is animal protection and I am a member of several animal rights organizations. I love being the mom of an active teenaged daughter who is an honor student and a passionate competitive dancer.

Long Thao

Born, raised and still residing in Minneapolis, I believe in building trust and relationships with the people of my community and providing comprehensive dental care. I keep a well rounded approach to the types of treatment I provide, which include preventive care, fillings, crowns/bridges, root canals, dentures and extractions. I am currently enrolled in a comprehensive Orthodontics (braces) course and look forward to helping patients achieve the smile they desire!

I knew dentistry was right for me the moment I began shadowing dental offices during my undergraduate years at the University of Wisconsin – Madison. This ultimately led to a degree from the University of Minnesota School of Dentistry. Being a dentist is the perfect blend of working with people and applying three subjects I have always enjoyed: engineering, art and science.

I am a member of the American Dental Association, Minnesota Dental Association and Academy of GP Orthodontics. I have worked with patients ranging from 6 months of age all the way to 102 years old. I truly appreciate dentistry in its entirety.

Outside of dentistry, I enjoy spending time with my wonderful wife (May) and daughter (Harper), fishing, watching football and playing disc golf. I am a proud Eagle Scout of Troop 100, where I currently serve as Committee Chairman.
