Weight Loss Medicine (Bariatrics):

If you are looking to lose weight by participating in a medically supervised weight loss program, we would like to help you.  Please visit our sister website, for further information.  We have found that weight related problems such as diabetes, hypertension, asthma, obstructive sleep apnea, hyperlipidemia and other medical problems can be brought under control with medical weight loss therapy.  Usually, medications relating to the above conditions can be reduced and sometimes eliminated by participation in a medically supervised weight loss program. 


Our office strives to be available at times when you are able to come in.  To that end, our office offers a range of appointment times.  We have morning appointments that start as early as 7:00 am and evening appointment as late as 6:00 pm.  Our office is also open during the lunch hour on dedicated days.  To facilitate these accessible appointment times our office offers 3 different providers to meet your needs, Dr. Knopke M.D., Sheila Stephens PA-C and Lesley Laird PA-C.

We are always striving to improve our office.  Recent measures include:

  • Adoption of an Electronic Medical Records System
  • Electronic prescriptions.  Your prescriptions will often be ready at the pharmacy before you arrive.
  • New patient paperwork is available on line to save you time
  • Specific Weight loss forms can be found here.
  • Adoption of an integrated weight loss practice.  Many health problems we see are best addressed through weight and lifestyle management.  We are set up in house to help you with your weight control needs.
  • Expanded office hours with morning, lunch and evening hours available.
  • Availability of an afterhours express care. that is open until 10:00p

We look forward to serving you.  Please contact our office with any questions.  If you would like to meet Dr. Knopke before establishing care just let our office staff know and we would be more than happy to set this up for you.
