Counted from their Google reviews up to September 2026. Something shows here once at least 3 patients mention it. Bigger clinics get more reviews, so compare with care. Google’s rating and review total change every day, so we round them down (like 4.5+ stars or 250+ reviews) to stay accurate until our next update. See today’s reviews on Google ↗

The team listed on their website.

Dr. Mark Keresztes
Dentists
Read bio

After receiving a Bachelor’s of Science from Queen’s University (and graduating on the Dean’s honour list, with distinction), Dr. Keresztes graduated from the University of Sydney with his Doctor of Dental Medicine in 2017. Since then, he has become an Associate Fellow for the American Academy of Implant Dentistry. Dr. Keresztes is enthusiastic about continuously broadening his scope of experience; and what he loves most about his job is “a good mix of personal and professional relationship between patient and dentist. From the first meeting ongoing, it’s important to establish trust between patient and dentist. Glendale Dental Centre gives us the opportunity to work in a place where trust and familiarity between patient families, and our family at the practice, is built over time. This is the basis of a good, long-term dental relationship.”

Dr. Amanda Slamka

Dr. Slamka received her Bachelor of Science in Medical Science with First Class standings at Brock University, and graduated from the University of Sydney with her Doctor of Dental Medicine degree in 2018. Dr. Slamka is passionate about dental education and wants her patients to feel involved in their dental care + decision making process. She enjoys all areas of General Dentistry, but is specifically interested in working with family groups. She excels in making her patients feel comfortable + confident at every appointment. Having been raised in St. Catharines, Dr. Slamka is thrilled to be back in her hometown and practicing dentistry surrounded by her family and loved ones.

Dr. David Janzen graduated from Case Western Reserve University with his Doctor of Medical Dentistry degree in 2004. He joined the team at Glendale Dental Centre at that time and has been offering a commitment to treating patients with compassion and care ever since. Born and raised in Niagara, he has a strong connection with the community personally through our local music scene. Professionally, his passion for outreach in our community is fulfilled by volunteering his dental services at a local healthcare centre. Family life on a small hobby fruit farm in rural St. Catharines provides the perfect balance to his professional events and commitments.

What do you need?

Pick one to see what they offer, what patients say and what to ask.

Check-up and cleaning

Questions to ask
  • Are you taking new patients, and when is the first opening for a new-patient exam and cleaning?
  • What will the exam, X-rays and cleaning cost, and what will my insurance or the dental care plan cover?

Cost and paying

Their website doesn’t list prices or ways to pay.

Before treatment, ask
  • What’s the total, including the exam and X-rays?
  • How much will my insurance or the dental care plan cover?
  • Does anything cost more than the provincial fee guide?

They don’t post prices online. For a rough idea, see what patients across Canada said they paid.
