I was a patient of Dr. Guerin but transferred to Dr. Douglass when he joined the office and I am so glad I did. Dr. Douglass never seems rushed and he listens to you. Most importantly, he explains everything in detail and is always polite and courteous.

Doctor Douglass was very through with he's explanation of my blood work everytime I've seen him. He also takes my healthy lifestyle into account when making his recomendations for what to do next. It took awhile to be able to see him because he was booked out but I was very happy when I did.

Crappy office staff, cobwebs abundant in filthy office, did not honor scheduled appointment that was verified by email. I do not recommend.

Dr Douglas is fine however I have had problems with office. Perhaps it is the phone system and fax system.problem. I have called them regarding a fax from my pharmacy twice each time they say they have no record. My pharmacy has faxed there number 3 times with no response. Today a working day I have called the office since a little after 2 pm to talk again with them. There is no answer have many repeated tries. The phone just rings and rings to voice mail then again as I try to get through
