Office Procedures:
We have several options if you should prefer not to come into our office. We would be happy to make you an appointment by a phone conference or zoom meeting rather than an in-person conference.
If you have documents you would like us to have please use one of these options:
• Scan the documents and email or upload to our secured file exchange portal
• Mail the documents
