No declension
When 'Doktor' (doctor) stands as a title before a name, the word is not declined. It keeps the same form in all cases.
EXAMPLE
Wir haben mit Frau Doktor Weber gesprochen.
We spoke with Doctor Weber.
Informal use
Using 'Doktor' (doctor) for a physician is very common in everyday language. It is often used with the prepositions 'zu' and 'bei'.

Doktor vs Arzt
doctor
'Arzt' and 'Doktor' can both be used for a person you go to because of a health problem. Strictly speaking, however, 'Arzt' is the job title. 'Doktor' is actually an academic title and can also refer to people who do not work in medicine at all. In everyday speech, many people still say 'Doktor' when they mean a doctor. The words can be confusing because you often hear 'zum Doktor gehen' (to go to the doctor) in everyday language. If you are speaking clearly and factually about the profession, 'Arzt' is more precise.
Doktor
Herr Doktor Weber erklärt der Patientin die Ergebnisse.
Doctor Weber explains the results to the patient.
Arzt
Nach dem Unfall hat der Arzt mein Knie untersucht.
