PDEC providers are unmatched when it comes to experience in assisting patients utilizing the latest in diabetes technology!

It hasn’t been that long since insulin injections were the only way to treat patients with diabetes.  Over the past several years technology has advanced to include not only oral and injectable medications but also devices to assist patients in monitoring their blood sugar levels.

Continuous Glucose Monitoring Systems (CGMS) & Insulin Pumps

Continuous Glucose Monitoring devices worn by patients do just as the name describes – continually monitor blood glucose levels!  Insulin pumps help eliminate the need for multiple daily injections and simplify the delivery of medications.  All PDEC providers are well versed in many brands of insulin pumps available on the market today as well as  supporting several CGMS options including Dexcom, Guardian, Libre and the new Eversense implanted CGMS system. Utilizing one of these devices along with an insulin pump has revolutionized the way patients manage their diabetes.

Type 1 Diabetes Mellitus

With deep roots in scientific research, innovation, and service, PDEC providers care for thousands of patients with type 1 diabetes, including 100+ patients living and thriving with type 1 diabetes for over 50 years!  Type 1 diabetes, also known as insulin-dependent diabetes and juvenile diabetes, can occur at any age but is most often diagnosed in children and young adults. 


Type 2 Diabetes Mellitus

Research has provided a plethora of treatment options for patients with Type 2 Diabetes. PDEC providers work with each patient to find the best and most cost-effective treatment option for them.

Pregnancy & Diabetes

Women with diabetes historically struggled to find well-educated providers to monitor their health during this exciting journey. PDEC has been here to help along the way and we continue to provide support and education throughout pregnancy.

RFA for Thyroid Nodules

RFA (Radio Frequency Ablation) is a non-surgical solution for shrinking thyroid nodules. RFA procedures are performed in the comfort of our office rather than an outside facility or surgical center. For more information on this procedure, contact our office.

Along with the various treatment options for this multi-faceted disease, our caring staff is skilled at addressing the specific needs of patients and their families.


Treatment options for osteoporosis have greatly increased in recent years. Every year PDEC providers help nearly 2,000 patients better understand what they can do to strengthen bones and decrease their risk of fracture.

When I was placed in the hands of [Dr. Bergstrom] after years of Type 1 Diabetes I was given a new life.  This man is more than knowledgeable he also takes a true role in your life as a guide, a friend and a brother.  My diabetes is what they call challenging.  I am always changing the way my disease is displayed.  I am grateful knowing I have the best there is in care and will never change my doctor as long as he is still practicing.  I have had to make insurance changes since I have Medicare and won’t give in to a cheaper plan if he isn’t on it.  I may be forced to pay a little more but if I do I won’t blink a eye.  Great service and care doesn’t have a price.  Thank you Dr. For everything!”
