Meet the Dentists:


Dr. James P. Thomas, Jr.

james-p-thomass-ddsI have met some wonderful people practicing dentistry in this community, and they all have something different to share. My mission is always to break down the wall of fear and create a bond of trust that will last the rest of their lives. Modern dentistry has improved in so many ways, and I love that I am able to bring these advancements to my patients.

Our office is blessed to have so many wonderful patients and we make every effort to provide quality, conscientious dentistry.

I grew up locally, attended Rochester Adams High School, and received both my Bachelor of Science and Master of Science degrees in Biological Science from Michigan State University. I completed my Doctorate degree in Dental Surgery, with distinction, from the University of Detroit-Mercy.

I have furthered my education by completing post-graduate training in dental implants and surgery, veneers and cosmetic restorations, laser therapy, and Invisalign. I take a special interest in providing a comfortable dental experience for my patients and am constantly taking continuing education courses. I take special interest in providing a comfortable dental experience for my patients and enjoy constant continuing education.

Dr. Derek Roos

As a native Michigander, I am thrilled to be back home and practicing in Michigan.  My focus is to create an environment where your entire family can feel at ease with dental treatment.  My goal is to create a comfortable setting to work with you and your family to optimize your oral health in a fun educational environment.

I earned my D.M.D. at Tufts University School of Dental Medicine in Boston, Massachusetts. During my time there I was actively involved in community outreach programs, school-based dental care, and providing care to homeless and high-risk youth in the Boston area.  Prior to dentistry, I worked in corporate finance for General Electric after earning a degree in Finance from Michigan State University.  Currently, my focus is furthering my education and technological advancement in dentistry through training in cosmetic dentistry, endodontics, implants and Invisalign therapy.

My wife Jill and I recently welcomed our first son Brendan and look forward to raising our family in Metro Detroit  I enjoy hockey, football, golf, wakeboarding and running with my golden retriever Summer.  My wife and I share a passion for travel and continually look forward to planning our next adventure.

Meet the Team:

Jamie- Dental Hygienist

I graduated from Baker College of Auburn Hills and have been a Registered Dental Hygienist for 5 years now.  I am licensed in nitrous oxide/local anesthesia administration and I thoroughly enjoy what I do.  My job is even more enjoyable due to the fact that I work with a wonderful group of people at Rochester Hills Family Dentistry.

My goal in the workplace is to educate patients on oral health as well as create a comfortable experience during dental cleanings.  Aside from being an RDH, I am a mother to a beautiful daughter and two feisty chihuahuas.  My husband and I love living in Rochester Hills and look forward to a long, happy future here!

Amanda-Dental Hygienist

When I became part of Dr. Thomas’ clinical staff in 2014, I immediately knew it was exactly the place I’d been looking for.  I am a Registered Dental Hygienist and I enjoy treating patients from differing demographics from healthy to severely diseased.  I can be confident in receiving my dental care in office and also bringing my family and friends in for treatment.  In my time away from work I enjoy spending it with my husband of 12 years, my 9 year old son and two dogs.  We spend our time together swimming, visiting parks and traveling.  I also enjoy volunteering my time as a hygienist and also as a mom in my sons school.

In June 2016 I relocated to Michigan and found my career home with Rochester Hills Family Dentistry.  I have been in the dental industry for 15 years, having worked in all aspects of the dental field; I love everything about what I do, but mostly I enjoy bringing confidence back to people’s smiles and comforting their fears.  I received my certification through DANB and Nova South Eastern University. I served 6 years in the US Army as a Health Care Specialist, serving in Military Hospitals through out the U.S.  In my free time, I enjoy spending time with my husband and three rambunctious children.
