Dr. Clewell is in it for each and every dollar. Today I called to get a prescription called in for some cough suppressant after having to go to a minute clinic yesterday. Because the clinic only has a nurse practitioner they are limited in what they can prescribe. I have flu diagnoses and received Tamaflu. Just needed cough syrup to sleep (can not take OTC). Wanted me to come in for office visit. Spent $100 for visit yesterday with Flu test. Willing to show them result but was refused. They wanted that office visit charge. I come in for check ups etc. POOR patient care! Smaller issues over the years as well.
