Professional Statement

I care for patients with obstructive sleep apnea (OSA) and am currently working toward Diplomat status with the American Academy of Dental Sleep Medicine, a certification for dentists who treat OSA with oral appliance therapy. I also collaborate with sleep physicians to identify the best treatment for each patient.


My patients’ overall oral health is my priority. While I love all aspects of general dentistry, I have a special interest in treating obstructive sleep apnea, Orthodontia, and restorative dentistry, including dental implants. I’m committed to lifelong education to ensure my patients receive the highest level of care.

I’ve taken numerous postgraduate education courses on advanced restorative dentistry, including an intensive dental implant program, and the medical model of collaborating with sleep physicians in treating obstructive sleep apnea. On a more cosmetic note, I have training in porcelain veneers and invisible braces, allowing me to offer my patients a noninvasive way to straighten and beautify their teeth.

As an active member of my community, I am fortunate to be able to volunteer my time and services to the Donated Dental Services Program and the Minnesota Dental Association’s Mission of Mercy. I’m very active with the St. Paul District of the Minnesota Dental Association (past president) and in 2003 was honored with the statewide Dentist Leadership Award.

I was a little surprised at the briefness of the visit as a new patient but perhaps it was because this was more of a cleaning appointment.

I was in for a tooth cleaning but Dr. Harrison always takes time to check in with me even though the hygienist was the person I had the appointment with. Everyone at this location is helpful, caring and cheerful.

I have been a patient of Dr. Harrison and the hygienist since Dr. Harrison began practice in St. Anthony Park. I am obviously more than satisfied with all the people in his office.

Time with the doctor is always very limited. I did not have time to formulate many of my questions regarding his recommendation for treatment for one concern mentioned at this visit. I would have appreciated a chance to ask about alternative treatments, time frame, etc. I don't really know this physician very well, with the limited time exposure over several visits, and I've never had him work on my teeth in the past.

I was called the day of the appointment to see if I could come earlier. I was able to but not told the reason why. The planned 2 visit crown procedure became a single visit for over 2 hours. I wasn't told about the increase in the visit time.

No treatment was needed. Time with dentist was short - I'm not sure if there was something going on that needed more of his time. I don't remember being asked by the dentist if I had any questions or concerns. I did, however.

Dr William Harrison is fantastic and his entire staff; everyone! I had not seen a dentist in years due to fear and the entire staff was efficient and understanding. Because of their excellent understanding and proper care I feel confident to return to them and get back on the right path of visits to the dentist!

Dentist and hygienist recognized that I have a unique condition. This is the FIRST time anyone had ever noticed (or mentioned) to me. However, once I got home and had the opportunity to look up more information -- I was so stunned that it had not come up before! Learning about the condition has explained some odd things that have cropped up over the years. The condition may offer an explanation for the gingivitis diagnosis and tissue grafts I underwent in high school. If the condition ever worsens, I now know where to seek help and what can be done about it. Thank you.

Dr. Bill is the best dentist I have visited to date. I was in no discomfort during the procedure, and felt very at ease. He thoroughly explained the procedure and multiple times asked if I had questions. Additionally, he did not make me feel that I had doomed myself by not seeing the dentist sooner--rather, he took care of my teeth without making me feel bad. He is the reason that I chose to return to Park Dental. I would recommend Dr. Bill and Park Dental to absolutely anyone.

The crown is much better than my temporary filling but more care could have bee n taken in regards to fitting the crown. My new crown sits too high and the rest of my teeth do not contact due to the incorrect crown fitting.

Dr. Harrison spent maybe 2 minutes with me after my cleaning was complete. He seemed very busy, and although it was my first time in, he didn't talk through anything with me in terms of my overall dental health or my xrays. I don't have a big issue with this because I don't have any current dental concerns, but I was expecting at least a general discussion about my dental history and current oral health.

I was a little surprised that the doctor didn't have any commentary for me on my overall dental health - the only areas we discussed were a filling I will need to have, and then quite a bit of time on recommending elective invisiline treatment. It made it seem like his primary focus was on selling additional treatment (which may just be my perception)

Good overall, but I wished I was better informed of exactly what was needed in terms of my cleaning. Being told that I needed a "Deep cleaning" on four separate operations was quite the shock. I understand that the dental office staff are pretty used to terms and procedure but taking more time to be sensitive to a client's understanding could be a great improvement.
