About Wyoming Medical Associates

Telehealth — or telemedicine — is a healthcare solution that allows you to meet with your doctor virtually instead of going to the office. Our 100% HIPAA-compliant system uses a two-way, high definition video, so we can talk face-to-face as if we’re in the same room together.
With Telehealth, you can also:
  • Submit your medication list, allergies, ID cards, and medical history in advance
  • Chat or share photos describing your symptoms
  • Have prescriptions electronically sent to your pharmacy
  • Securely pay online for your virtual visit
This streamlined approach originally evolved to help expand medical care to men, women, and children living in remote areas. Today, 76% of hospitals use Telehealth technology, and US employers could save as much as $6 billion a year by making telemedicine technology available to their employees. But the advantages of Telehealth go far beyond financial savings.

What Our Patients Say

Testimonials
  • 5 star review  There was an unforeseen difficulty with my procedure. Rather than taking the chance of injuring me, Dr. Rinker referred me to a surgeon in another location where it could be performed in a safer manner. I respect him for taking that action. Trish, the APRN in this practice, is very competent and easy to work with. I would recommend this practice highly.

    5 star review  Dr. Rinker took the time to explain my vein condition to ensure I understood what was going on. He explained the processes available for treating it, answering my questions along the way, explaining during procedures what was happening at particular intervals. His staff have been incredibly helpful and friendly, and being able to have vein procedures and follow-up ultrasounds in one practice has made the process very smooth. I've been pleased overall with my experience.
