Partnering with You for the Health of Your Patients – Our Goals


To make referral as easy and time efficient as possible. Referrals can be made in several ways.

  • Give the patient one of our business cards and ask them to call us and schedule.
  • Fax the patient demographics and reason for request, and we will call the family to schedule an appointment.
  • Call us during business hours and we will give you an appointment time that you can give to the patient.
  • For next day or Hospital follow-up, call our office any time. If it is outside business hours, our answering service will contact us so that we can arrange a time for the patient to be seen.



To keep routine new patient consult wait time to 2 weeks or less. Still if the scheduled appointment time is too distant, or for special requests, please feel free to contact our office. We will do what we can to accommodate the schedule you feel is appropriate.




To visit local offices in person to advise them of our services and policy. Also to get any way that we can service you better. I will be leaving business cards that you can use at your convenience. Please let us know if you do not receive a visit and would like one or would like a supply of cards.



Follow up with you promptly regarding the status of your patient. We will send you
consultation notes by USPS mail within one week of your patent’s visit.
