COVID-19 Updates

(updated 1/3/22)

We are pleased to welcome all patients back into the office starting 5/3/21.  We are following CDC guidelines, including wearing masks and social distancing in the office.  It is important that we see patients in the office to monitor things that were not able to be measured virtually, such as blood pressure, weight, and physical exam findings.  We will try to keep some appointments for virtual visits available moving forward, for your convenience.  This will need to be arranged in advance with our office.   Please note that we may need to pivot back to virtual visits in the event of worsening COVID-19 infections or staffing shortages.  Please be patient with this process.  We will contact if our strategy for seeing patients changes.  We are looking forward to having you back in the office.  For new patients, please arrive 30 minutes prior to your scheduled appointment for registration and paperwork.  If you are an established patient, please arrive 15 minutes prior to your scheduled appointment time and bring your driver's license and insurance card as they will need to be scanned into our new electronic health record.  If you have questions regarding this change, please call the office at 727-477-1039 or email us back at

Please do NOT come to the office and please call us if you are ill (have a fever, cough, shortness of breath, diarrhea, vomiting, etc.), had exposure to someone who has been sick, or have recently traveled and come down with illness.  Please find the latest COVID-19 updates here.

For new patients, please go to our Healow patient portal website (click the link) to fill out your new patient paperwork well in advance of your appointment.  Please click the link in the bottom right to pre-register if you do not yet have an appointment and we will call you to set one up as you enter your demographics.  Please also fill out the new patient intake questionnaire with your health information.  This will help us to gather the necessary information and save you time at check-in as you arrive for your new patient appointment.  Again, we are seeing new patients in the office with appropriate cleaning before and after each patient and social distancing.  We ask that you arrive to the office 30 minutes prior to your scheduled new patient appointment to ensure we have adequate time for paperwork and computer input.  We also require that you bring a face covering of some sort to your visit (mask or cloth) to be seen.  We will also be performing temperature checks prior to seeing you for safety.

For new and estabilshed patients with diabetes, please keep a logbook of your glucose values over the last 2 weeks and email them to me prior to your live or virtual / telehealth visit: You may also send them through the patient portal if that is easier for you. I have included a glucose logsheet for your convenience. Please click the link for it. Please fill it out and email it to us prior to the visit (or take a picture of it with your phone and email it if you are unable to scan the document after it is filled out).  

For established patients on Medtronic insulin pumps, it would be immensely beneficial if you could upload 2 weeks of data from your pump at home on your computer prior to your visit.  The instructions are available on this link to assist you in this process: Medtronic Carelink pump uploading.

I have also included a large number of resources to help with the cost of your medications and insulins under the "For Patients" tab.  Please check it out for direct links to assist you in this difficult time. 

I look forward to seeing you soon and will continue to strive to deliver the best endocrine care possible.

Thank you for being a patient at Lake Endocrinology and Diabetes, PLLC. Please stay safe and let me know if there is anything that you need during this trying time.
