Are these correctly punctuated?

This pleasant patient has been seen for therapy from February 2, 2005 to March 2, 2005.

This patient comes in today with many, many complaints.

This year she'll have a breast augmentation and next year she will have an abdominoplasty.

Depression, often a genetic disorder, can be safely treated with medication.

No, I do not agree with that diagnosis.

#1 -- another comma is needed after 2005.

#2 -- OK

#3 -- a compound sentence; where will you add a comma?

#4 -- OK

#5 -- OK

Looks very good to me!

However, some teachers will want a comma after "augmentation", but as it is is equally correct.

Yes, except for the last sentence, the provided sentences are correctly punctuated. Here is the breakdown of each sentence:

1. "This pleasant patient has been seen for therapy from February 2, 2005 to March 2, 2005."
- The sentence is correctly punctuated with a full stop at the end. The comma is correctly used to separate the dates ("February 2, 2005" and "March 2, 2005").

2. "This patient comes in today with many, many complaints."
- The sentence is correctly punctuated with a full stop at the end. The commas are used to indicate emphasis on "many" complaints.

3. "This year she'll have a breast augmentation and next year she will have an abdominoplasty."
- The sentence is correctly punctuated with a full stop at the end. The apostrophe is used in "she'll" to denote the contraction of "she will."

4. "Depression, often a genetic disorder, can be safely treated with medication."
- The sentence is correctly punctuated with a full stop at the end. The commas are used to set off the non-essential phrase "often a genetic disorder."

However, the last sentence "No, I do not agree with that diagnosis" is missing a full stop at the end. It should be: "No, I do not agree with that diagnosis."
