Words from the practices we’ve worked with

What it’s like to work with Tammy.

Across 38 years of dental practice transformations, the same themes keep surfacing in client letters: presence, persistence, the willingness to confront, the courage to teach. Here’s a curated cross-section — doctors, office managers, students, and outside observers — in their own words.

From the doctor’s chair

Dentists on the work.

Practice owners describing what changed after Tammy and David came into the office — numbers, team chemistry, leadership confidence, the quiet relief of finally being able to go home.

I have had the pleasure of working with Tammy and David for over ten years. Tammy originally worked with my practice as a Dentrix consultant and later transitioned into my practice consultant. In my thirty plus years in dentistry I have been through some difficult times and some very exciting times. I can tell you that growth and change is the only constant and it is not easy. Without Tammy and David in my life I would be lost when it comes to managing staffing and my business. They are my rock to lean on, my friends to confide in and an integral part of my team and of my success. As a friend and as a business partner I can never thank them enough for what they both have given to me and for what they have done for me. Thank you both from the bottom of my heart!

Practice Management Systems has been monumental in starting my practice. They are experts at what they do and I love that Tammy and David have surrounded themselves with an amazing team of professionals to help cover every need they anticipated we would encounter as we built Andersen Dental Center. Hiring can be very difficult, but Tammy was phenomenal at knowing how to staff my team with people that share a common vision. Because of the countless hours that Tammy puts in, I can go home at night and focus on my kids.
We saw immediate positive changes financially but even more importantly in the “emotional” health of the practice. The staff all work so well together and the laughter has returned. A true testament for the philosophy that “people don’t fail, systems do” — and we finally have the systems that succeed in place.

We experienced immediate gains in our numbers within the first month of hiring her company. With Tammy’s guidance, we continued to see these improvements in our numbers years after acquiring her services. I give Tammy and Practice Management Systems the highest of recommendations.
Our team is at another level due to the efforts of Tammy and her systems. She really cares on a personal level. Her knowledge is very valuable for all dental offices. Now I can practice dentistry instead of micromanaging.
I am an associate at an office that Tammy supports and I have seen that she makes a big impact in keeping our office moving forward and in the right direction. She has a large hand in the success of our office and in the great chemistry that has been fostered here.

Tammy and her team did an excellent job in helping me turn my business around. This was the first time I’ve ever used a dental consultant and I’m really glad I did. Professional, knowledgeable and easy to work with.
King Dental
Dr. Brad King King Dental
One of the major factors for us in choosing Tammy over other consultants was her availability IN the practice. Many others rely on a day or two of training and leave the burden of implementation to you. Tammy has been a consistent presence in our practice and I know that it has been a tremendous help in implementing the systems.
Mark Swensen North Point Dental Group
Tammy has helped us craft a vision for our practice, and has implemented systems that have improved our production, case acceptance, quality of life, and the overall patient experience. In addition, Tammy has invested in me personally and given me the confidence and skills to be a leader, even though I am less than a year out of dental school.

From the front desk & the team

Office managers, hygienists, and the people who run the day.

The people who feel the systems first — and who decide whether they stick.

Tammy was here to help us be successful from day one — even spending entire weeks with our office when we first began. She will answer the phone at any time of the day, and work miracles to come into the office that same day if she is needed. She has coached me from simple dental knowledge, dentrix software, systems for measuring treatment acceptance, as well as keeping the team happy and conflict free.

She has been an integral part to our practice growing leaps and bounds. She always sees the potential in our staff and knows how to push and encourage us to ‘work smarter, not harder.’
Amber Shin Valley Endodontics
I am so thankful to have the opportunity to work with both of them. They are very knowledgeable within all aspects of how a dental office should run. I highly recommend them if you are looking to start or make some improvements on the operation of your current practice.

She motivated me to work hard and put 110 percent into everything I did. She genuinely cares about not only success, but well-being of everyone around her, and cares enough to confront, support, and drive to success.

Tammy, with Practice Management Systems, helps us problem solve and helps us identify solutions that actually work. We were doing ok, and now we are running even smoother and more productive.
Chandra White Hollywood Family Dentistry
She is a great teacher and wonderful to have around. She looks at all offices individually and custom fits each practice. I just have to smile when I look back to see how far we have come.
Front office course graduates

Students who walked in green and walked out hired.

Tammy’s Front Office Course has trained dental admins, schedulers, and treatment coordinators across the Pacific Northwest. A few of their words.

Being a busy full-time mom of 3 and deciding to change careers, I cannot tell you how fortunate I am to be a part of Practice Management Systems. I, being someone who has no dental history background whatsoever, have learned so many things. They have given me the education, tools, and systems that has given me the confidence to go into a dental practice and show them what I can do.

Diedra Christensen Front Office Course graduate · Chapman Smiles
I made the commitment to travel 3.5 hours each way, every week from Kennewick, WA to Oregon City, to seize the opportunity to find a new career in the dental field. As my class term is coming to a close, I am anxious to apply my new skills I’ve learned from Tammy into a new adventurous career.
Jamie Taylor
Jamie Taylor Front Office Course graduate · Kennewick Dental
Tammy provides labs, workshops, and additional support for each individual student. She truly cares about dentistry and her students. Any dental office I had recently contacted was truly amazed at what I was being taught and trained on, without even stepping into a dental office.
Val Yakis
Val Yakis Front Office Course graduate · Pioneer Dental Group
Tammy makes this class fun, and more like a conversation than a class. She’s a wealth of knowledge. If you are curious about the dental field, how it functions and how to run it, then this is an ideal place to start.

Tammy is an expert. She is one of the hardest working people I know, and her methods are consistent and effective. I’ve worked with Tammy in many practices, and she always helped grow their patient counts, establish a team culture and take stress off the doctors she works so hard to support.
Mark S. Yelp Review
My dental practice would not be the success that it is today without her help. She has the knowledge to teach, the strength to lead, and the courage to confront the challenges that sometimes face our profession.
Susan W. Yelp Review
Through true caring and a sincere desire to mentor, Tammy has renewed my wife’s interest in pursuing a rewarding career. I have witnessed a huge change in my wife’s personal abilities as well — she is more confident, proud, willing to take on any challenge.
Don B. Yelp Review
Tammy comes from a coaching and HR background and she has an amazing set point where she is helpful, kind, but yet will kick your butt if you are off track. When I have talked to people that don’t like their jobs or just didn’t have direction, I’ve sent them to Practice Management Systems.
Paul H. Yelp Review
Family integrated, highest ethics and professionalism, top quality products and services, excellent customer service, outstanding results for their customers, fast growing, and fun to work with.
Scott Landis Industry partner
Practice Management Systems is filling a much needed void in the dental field by offering skilled professionals to train new people into our business. I so appreciate your willingness to invest your time, money and talent to help others.
