Meet the Team

Yeremi Canizales, DDS, MS


I was originally born in Caracas, Venezuela, and my family and I immigrated to the United States in the fall of 1987. As a boy, my family instilled in me the importance of education, perseverance, integrity, respect and loyalty among other values.

Fast forward thirty years and these same values continue to guide my actions and help me better serve my patients and community.

I attended Wheeling Jesuit University, where I received my Bachelor of Science. I continued on to earn a master’s in microbiology from Thomas Jefferson University. I graduated from West Virginia University School of Dentistry in 2011. Since graduating from dental school, I have acquired additional training in areas of Invisalign®, BOTOX®, implant dentistry, full-mouth rehabilitation and obstructive sleep apnea.

I am proud to say that, over the years, we have helped many patients achieve their health and aesthetic goals. It is my hope that we can be of service to you!

Amanda McPherson, DDS, MS


I am so excited about being a part of the team at Severn River Dental Health Center. I feel so amazingly blessed to have found a profession that I love and that I can share that passion with my staff and my patients. I really believe that, along with Dr. Yeremi (my hubby) and our awesome staff, we are changing the way that people experience dentistry.

Whether I am just keeping my patients healthy or helping them create a new, comfortable smile, it is truly a privilege to serve this community and all of the wonderful people of Severna Park and the surrounding area. I have been practicing here for over five years now, but I am originally from the Northern Panhandle of West Virginia.

I met my husband, Yeremi, during my first year of college and spent many years visiting Maryland. I always knew it was where I wanted to settle down, work and raise my family. When I am not providing my favorite treatments, such as custom dentures or oral appliances for sleep apnea, I am home enjoying quality time with my beautiful children — Genevieve and Graynger.
